# Power conversion

Power conversion is a free online calculator for converting metric and imperial units of power. Conversion between watt, kilowatt, horsepower, joule/second, Btu/hour, calorie/second ...

joule/second (j/s) - unit of power. 1 j/s means 1 joule of energy is produced in 1 second

joule/minute (j/m) - unit of power. 1 j/m means 1 joule of energy is produced in 1 minute

joule/hour (j/h) - unit of power. 1 j/h means 1 joule of energy is produced in 1 hour

watt (W) - most used unit of power that is equal to 1 joule/second. Unit is named after James Watt

kilowatt (kW) - unit of power. Kilo prefix is a SI prefix and means thousand.

megawatt (mW) - unit of power. Mega prefix is a SI prefix, and means million.

gigawatt (gW) - unit of power. Giga prefix is a SI prefix, and means 10

^{9}.Btu/second - unit of power. Today is Btu/second replaced with joule/second.

Btu/minute - unit of power. Today is Btu/minute replaced with joule/minute.

Btu/hour - unit of power. Today is Btu/hour replaced with joule/hour.
