20 Watt-hour = 2.0E-8 Gigawatt-hour
Watt-hour to Joule | Watt-hour to Btu (IT) | Watt-hour to Kilojoule | Watt-hour to Calorie (IT) | Watt-hour to Erg | Watt-hour to Watt-second |20 Watt-hour equal 2.0E-8 Gigawatt-hour.
Every 1 Watt-hour = 1.0E-9 Gigawatt-hour and so, 20 Watt-hour = 20 multiplied by 1.0E-9 = 2.0E-8 Gigawatt-hour.
