This calculator allows you to convert from Watt to Joule/hour and in a reverse direction. To convert from Watt to Joule/hour, enter the amount of Watt into the first input and to convert from Joule/hour to Watt, enter the amount of Joule/hour into the second input.
20 Watt = 72000 Joule/hour
Watt to Erg/second | Watt to Horsepower | Watt to Pferdestarke (ps) | Watt to Foot pound-force/minute | Watt to Kilocalorie (th)/hour | Watt to Btu (IT)/hour |20 Watt equal 72000 Joule/hour.
