How to Convert Volts to Watts (V to W)

Converting volts to watts is easy — you just need to know the current in amps. To convert volts to watts, simply multiply volts times amps.

Formula: watts = volts × amps

Abbreviated: W = V × A

Occasionally, you may also see watts abbreviated as P instead of W and amps abbreviated as I instead of A. The conversion formula remains the same.

Alternate abbreviation: P = V × I


Here’s a simple example illustrating how to convert volts to watts.

Let’s assume you have own the following solar panel that is rated at 18.6 volts and 5.38 amps.

To calculate the watts produced by the panel in full sun, you would multiply volts times amps.

18.6 volts × 5.38 amps = 100.07 watts

It turns out your panel is a 100 watt solar panel.

Why Convert Volts to Watts?

Knowing a devices wattage is necessary for estimating how much power it’s using at a given moment, as well as how much energy it consumes overall.

For example, let’s say you have this portable 12 volt fridge.

You look at its product specifications and see that it has a max current of 5 amps. To estimate its max power consumption in watts, you multiply its voltage by its amperage.

12 V × 5 A = 60 W

So, in this example, your 12 volt fridge uses a max of 60 watts.

It’s important to know that the current rating listed on a device is usually its max current rating. In other words, the device may not be always using that much current. Fridges, for instance, enter a cooling cycle when the internal temperature gets too high. During a cooling cycle, a fridge is using much more energy than when it’s simply insulating.

Knowing the wattage of your devices helps you do three main things when it comes to DIY solar power:

  1. Size an inverter
  2. Estimate energy usage
  3. Size a battery bank
1. Sizing an Inverter

Inverters are rated in watts. If you know the wattage of all your devices, you can sum them together to get your system’s total power draw. This is the total watts being used if all your devices were running at peak power simultaneously.

For instance, let’s say you plan to run a 200 watt fridge and a 75 watt fan off your inverter. You’d find your system’s max power draw by summing the wattage of these two devices.

200 W + 75 W = 275 W

Your inverter needs to have a watt rating higher than this total. So a 250 watt inverter would be insufficient, but a 500 watt inverter would work.

2. Estimating Energy Usage

Power is rated in watts, but energy is rated in watt hours or kilowatt hours. To estimate energy usage of your house or DIY electrical system, you need to convert watts to watt hours (or watts to kilowatt hours).

To do so, you need to know the wattage of all your devices as well as how many hours per day each one will run on average.

If you have a 75 watt TV that runs for 2 hours each day, for instance, you can estimate its watt hours (Wh) by multiplying watts by hours.

75 W × 2 hrs = 150 Wh

Each day, your TV uses about 150 watt hours of energy.

3. Sizing a Battery Bank

The amount of energy a battery stores can also be expressed in watt hours or kilowatt hours. (Though often it is expressed in amp hours, which must be converted to watt hours or kilowatt hours.) So, if you know your estimated energy usage, you can use that number to size your battery bank.

For example, let’s say you’re designing a small off-grid solar power system. All together, you expect your devices to consume 200 watt hours per day. You want your battery to last for up to 3 days without recharging, so you could size your battery bank by multiplying the two numbers together to get the total energy usage of your system over the course of 3 days.

200 Wh/day × 3 days = 600 Wh

In this simplified example, your battery bank needs to have a capacity of at least 600 watt hours to meet your energy requirements.

How to Convert Watts to Volts (W to V)

To convert watts to volts, divide watts by amps.

Formula: volts = watts ÷ amps

Abbreviated: V = W ÷ A

Alternate abbreviation: V = P ÷ I


For example, let’s say you have a 300 watt solar panel that is also rated at 12.5 amps. You want the panel’s voltage. Simply divide watts by amps to get volts.

300 watts ÷ 12.5 amps = 24 volts

Turns out your panel is a 24 volt solar panel.

How to Convert Amps to Watts (A to W)

To convert amps to watts, multiply amps times volts.

Formula: watts = amps × volts

Abbreviated: W = A × V

Alternate abbreviation: P = I × V


Let’s say you have a portable travel oven you want to use while on a road trip in your campervan. The oven is rated at 12 volts and 10.8 amps.

You calculate the maximum watts used by the oven by multiplying amps times volts.

10.8 amps × 12 volts  = 129.6 watts

«220 V» or «230 V» — standard voltage in Russia?

And so the question is: “ What voltage should be in our network 220V or 230V? » At first glance, a very simple question. And a very simple answer: «There must be 220V in the network.» Indeed, since childhood we know that there are 220 volts in the socket and this is life-threatening. At the plant, factory and office, each outlet must be labeled «220V». On the door of the transformer box: “Don’t get in — it will kill you! 220V/380V».

However, this is not a completely correct answer. Currently, in Russia, the standard voltage in the network is 230V, but 220V is valid for electricity suppliers. Indeed, earlier in the Soviet Union the standard voltage was 220V, but later decisions were made to switch to the pan-European standard — 230V. According to the requirements of the interstate standard GOST 29322-92, the mains voltage should be 230V at a frequency of 50 Hz. The transition to this voltage standard was to be completed in 2003. GOST 30804.4.30-2013 also mentions the need for measurements at a standard voltage of 230V. GOST 29322-2014 defines a standard voltage of 230V with the option to use 220V. Power grids supply electricity in accordance with the current GOST 32144-2013, which establishes a voltage of 220V.

A change in the standard voltage value has been made to fully comply with European power quality standards. Of all the former republics of the USSR, Russia, Ukraine, and the Baltic countries have switched to the 230V standard.

At the same time, it should be understood that electrical equipment manufactured in Russia and for Russia should work normally both at a voltage of 220V and at a voltage of 230V. For devices, as a rule, the voltage range is set from -15% to +10% of the nominal voltage.

Geography of countries with standard voltages: 100V, 110V, 115V, 120V, 127V, 220V, 230V, 240V

Different countries around the world have adopted different mains voltage standards. You can meet the following standards:

  • 100V Japan
  • 110V in Jamaica, Haiti, Honduras, Cuba
  • 115B in Barbados, El Salvador, Trinidad
  • 120V in USA, Canada, Venezuela, Ecuador
  • 127V in Bonaire, Mexico,
  • 220V in many Asian and African countries
  • 230V in many European countries and parts of Asia
  • 240V in Afghanistan, Guyana, Gibraltar, Qatar, Kenya, Kuwait, Lebanon, Nigeria, Fiji.

What voltage is suitable for electrical appliances 220V or 230V

We managed to find out that the standard voltage in Russia today is 230V. In practice, of course, the voltage in the network is constantly changing and depends on many factors. What voltage is satisfactory for electrical appliances used in our home? There is no single answer to this question. The range of permissible voltages for each device is determined by the technical data of the product passport. Often the allowable voltage range is indicated on the back of the product or on the electrical plug of the device. So modern computers can operate at a voltage of 140 to 240 volts, a phone charger from 110 volts to 250 volts. The most demanding on the quality of the power supply are devices that have electric motors (refrigerators, air conditioners, washing machines, heating boilers, pumps).
It is clear that for any devices used in Russia and voltage 220V and voltage 230V is good.

What are the deviations in the quality of electricity

It is well known that our networks often have significant deviations from power quality standards. And the voltage can be much lower than 220V or much higher than 230V . The reasons for this phenomenon are also known: aging of existing electrical networks, poor maintenance of networks, high wear and tear of network equipment, errors in network planning, a large increase in electricity consumption. Network problems include: low and low voltage, high and high voltage, power surges. voltage dips, overvoltage, current frequency change.

Current to Watt Calculator

Current to Watt Calculator

To independently calculate the ratio of Amp / Watt or W / A, you need to use the well-known Ohm’s law. Power is numerically equal to the product of the current flowing through the load and the voltage applied to it. It is determined by one of three equalities: P \u003d I * U \u003d R * I² \u003d U² / R.
Therefore, to determine the power of the source of energy consumption, when the current strength in the network is known, you need to use the formula: W (watts) \u003d A (amps) x I (volts). And in order to make the reverse conversion, it is necessary to convert the power in watts to the power of current consumption in amperes: Watt / Volt. When we are dealing with a 3-phase network, we will also have to take into account the coefficient 1.73 for the current strength in each phase.

How many watts in 1 ampere and amperes in watt?

Permissible discharge of a car battery up to 30% of its original capacity (voltage not lower than 11.8V). Note that at this level, you can start the engine only at positive temperatures. In winter, do not allow even 50% discharge percentage (12.1V).

The square root of three is approximately 1.73.

That is, in one watt 4.5 mAm (1A = 1000mAm) at a voltage of 220 volts and 0.083 Am at 12 volts.
When it is necessary to convert current into power (find out how many watts are in 1 ampere), then apply the formula: 380 V.
So, if we are dealing with a 12 volt car network, then 1 ampere is 12 watts, and in a 220 V household electrical network, such a current will be in an electrical appliance with a power of 220 W (0. 22 kW). In industrial equipment powered by 380 volts, as many as 657 watts.

To convert Watts to Amps at AC or DC voltage, you need the formula:
I \u003d P / U, where
I is the current strength in amperes; P — power in watts; U — voltage in volts, if the network is three-phase, then I \u003d P / (√3xU), since you need to take into account the voltage in each of the phases.

Why you need a calculator

The online calculator allows you to quickly convert current into power. It allows you to recalculate the current consumption of 1 Ampere into Watts of power, of any consumer at a voltage of 12 or 220 and 380 Volts.

Such a power transfer is used both when selecting a generator for current consumers in a 12-volt DC car’s on-board network, and in consumer electronics, when laying wiring.

Therefore, a calculator for converting power into amperes or current into watts will be required by absolutely all electricians or those who are engaged in it and want to quickly convert these units.
