This calculator allows you to convert from Joule to Watt-hour and in a reverse direction. To convert from Joule to Watt-hour, enter the amount of Joule into the first input and to convert from Watt-hour to Joule, enter the amount of Watt-hour into the second input.
20 Joule = 0.0055555555555556 Watt-hour
Joule to Btu (IT) | Joule to Kilojoule | Joule to Calorie (IT) | Joule to Erg | Joule to Watt-second |20 Joule equal 0.0055555555555556 Watt-hour.
Every 1 Joule = 0.00027777777777778 Watt-hour and so, 20 Joule = 20 multiplied by 0.00027777777777778 = 0.0055555555555556 Watt-hour.
