Kilowatt-hour conversions

A kilowatt-hour converts directly into the other units of energy. 1 kWh equals 1000 Wh, 0.001 MWh, 3600000 J and 3600 kJ.

In British thermal units, 1 kWh equals 3412.14163312794 BTU (IT) and 3.41214163312794 kBTU. Conversely, with Energy: 1 and Unit: BTU (IT) (BTU), the kilowatt-hour card reads 0.000293071070172222 kWh.

Worked conversions

Entering Energy: 0.1 with Unit: Kilowatt-hour (kWh) returns cards including Watt-hour: 100 Wh, Megawatt-hour: 0.0001 MWh, BTU (IT): 341.214163312794 BTU and Joule: 360000 J.

Entering Energy: 10 with Unit: Kilowatt-hour (kWh) returns cards including Watt-hour: 10000 Wh, Megawatt-hour: 0.01 MWh, BTU (IT): 34121.4163312794 BTU and Joule: 36000000 J.

Starting from other units works the same way: 1 Wh gives 0.001 kWh and 0.000001 MWh, while 1 MWh gives 1000000 Wh and 1000 kWh.
