## KWh And MW

*posted by ***Michael:**

kW h (Kilowatt Hour) is a unit of ENERGY, which means energy used in an hour. MW (megawatt) is a unit of POWER, which is energy per unit of time.

- A unit for
**kW h** is kilo joules. - A unit for
**kW** is kilo joules/sec.

To convert between these 2 different units, you therefore need to have an extra dimension (time).

## The Missing Link

*posted by ***Psudo:**

If you're looking to convert from kWh to MW or visa-versa, the confusing bit is that you are assuming average or consistent energy consumption over time. You have to make that assumption explicit before the formula makes any sense.

1 MW * 1 h = 1,000 kWh

1,000 kWh/yr = 114.077116 W
