The **Power Conversion Calculator** will *convert* among different units of power including *Watt, kW, MW, GW, hp, BTU and calories*.

**convert**between the following

**units of power**:

*gigawatts, megawatts, kilowatts, watts, milliwatts, horsepower, horsepower (metric), BTU/h, calorie/h.*

- Gigawatt (GW) converter
- Megawatt (MW) converter
- Kilowatt (kW) converter
- Watt (W) converter
- Milliwatt (mW) converter
- Horsepower (hp) converter
- Horsepower (metric) (hpm) converter
- BTU/h (BTU/h) converter
- Calorie/h (cal/h) converter

## How shall I use the Power Unit Converter?

Select the unit of power you want to convert from, then the unit you want to convert to. Next, enter the power value you want to convert. The power unit conversion happens immediately. Our **Power Conversion Calculator** works in *both directions*: If you enter a value in the other field, it can also change the unit back from it. You can also decide how many decimal places you would like to see in the result.

## How shall I convert between units of power?

**Conversion between power units usually involves a simple multiplication or division**. You only have to know the correct conversion rate. This piece of information is enough to be able to convert 1 mile to km. Let’s take a simple example!

Let’s say that you want to find out how many kilowatts are 200 horsepower. We know that 1 horsepower (hp) = 0.7457 kilowatts (kW) (so this is the conversion rate between horsepower and kilowatt). So if you want to calculate how many kilowatts 200 horsepower are, you need to do the following:

- You only have to multiply 200 with the conversion rate (i.e. with 0.7457).
- The result 149.14, so 200 horsepower (hp) = 149.14 kilowatt (kW).

OK, but what if you want to make a power conversion in the opposite direction? If you want to convert from kilowatts to horsepower, you have to use the conversion rate mentioned above. Yet, this is the opposite direction, so instead of multiplication, we use the conversion rate for division. In this example it means:

You would like to know how many horsepowers 149.14 kilowatts are.

- Divide 149.14 by 0.7457.
- The result is 200 (g).
