About Kilowatt-hour (thermal)
Kilowatt-hour (thermal) is shown as a thermal-energy label and uses the same joule definition as kWh (3.6 MJ).
About Calorie
The small calorie (cal) is 4.184 J in this converter (thermochemical). Do not confuse with the dietary kilocalorie (kcal).
How to convert kilowatt-hour (thermal) to calories
1 kilowatt-hour (thermal) is equal to 860420.65009560226463 calorie when both are expressed in joule-equivalents:
1 kwh_th = (3,600,000 J ÷ 4.184 J) cal = 860420.65009560226463 cal
Each kilowatt-hour (thermal) is defined as 3,600,000 J and each calorie as 4.184 J in this tool, so one kwh_th equals 3,600,000 ÷ 4.184 cal = 860420.65009560226463 cal.
Let d(kwh_th) be the numeric amount in Kilowatt-hour (thermal) (kwh_th), and d(cal) the amount in Calorie (cal). Then:
d(cal) = d(kwh_th) × (3,600,000 / 4.184)
Equivalently, divide by how many kwh_th fit into one cal (joules per cal divided by joules per kwh_th):
d(cal) = d(kwh_th) ÷ 0.00000116222222
Or: calorie = kilowatt-hour (thermal) ÷ 0.00000116222222
Examples
Example #1: Convert 1 kwh_th to calorie
1 kwh_th = 1 kwh_th × (3,600,000/4.184) cal = 860420.6500960001 cal
1 kwh_th = 1 kwh_th ÷ 0.00000116222222 = 860420.6500960001 cal
Example #2: Convert 10 kwh_th to calorie
10 kwh_th = 10 kwh_th × (3,600,000/4.184) cal = 8604206.5009599999 cal
10 kwh_th = 10 kwh_th ÷ 0.00000116222222 = 8604206.5009599999 cal
Summary
To convert Kilowatt-hour (thermal) to Calorie, multiply the value in kwh_th by the ratio of joules per kwh_th divided by joules per cal. Equivalently: value_cal = value_kwh_th × (3600000 / 4.184). Numerically, 1 kwh_th equals 860420.6500956023 cal.
Relationship context
You are converting between electrical energy (watt-hours) (Kilowatt-hour (thermal)) and food / nutrition energy (calories) (Calories). All values are mapped through joules first. The numeric factor is 8.604207e+5.
