Kilocalories to gigawatt-hour Conversion
1 kilocalories (kcal) is equal to 0.000000001162222222 gigawatt-hour (GW⋅hr).
1 kcal = 0.000000001162222222 GW⋅hr
or
1 GW⋅hr = 860420650.1 kcal
Formula
To convert a energy from kilocalories (kcal) to gigawatt-hour (GW⋅hr), divide the energy in kilocalories by 860420650.1
e(GW⋅hr) = e(kcal) / 860420650.1
Examples:
Convert 10 kilocalories to gigawatt-hour:
e(GW⋅hr) = 10kcal / 860420650.1 = 0.00000001162222222 GW⋅hr
