About Kilocalorie
The kilocalorie (kcal) is 1,000 calories in the nutrition sense—often labeled “Calorie” on food packaging. Here 1 kcal = 4,184 J (thermochemical calorie definition used in this tool).
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).
How to convert kilocalories to kilowatt-hour (thermal)
1 kilocalorie is equal to 0.00116222222222 kilowatt-hour (thermal) when both are expressed in joule-equivalents:
1 kcal = (4,184 J ÷ 3,600,000 J) kwh_th = 0.00116222222222 kwh_th
Each kilocalorie is defined as 4,184 J and each kilowatt-hour (thermal) as 3,600,000 J in this tool, so one kcal equals 4,184 ÷ 3,600,000 kwh_th = 0.00116222222222 kwh_th.
Let d(kcal) be the numeric amount in Kilocalorie (kcal), and d(kwh_th) the amount in Kilowatt-hour (thermal) (kwh_th). Then:
d(kwh_th) = d(kcal) × (4,184 / 3,600,000)
Equivalently, divide by how many kcal fit into one kwh_th (joules per kwh_th divided by joules per kcal):
d(kwh_th) = d(kcal) ÷ 860.42065009560224
Or: kilowatt-hour (thermal) = kilocalorie ÷ 860.42065009560224
Examples
Example #1: Convert 1 kcal to kilowatt-hour (thermal)
1 kcal = 1 kcal × (4,184/3,600,000) kwh_th = 0.0011622222 kwh_th
1 kcal = 1 kcal ÷ 860.42065009560224 = 0.0011622222 kwh_th
Example #2: Convert 10 kcal to kilowatt-hour (thermal)
10 kcal = 10 kcal × (4,184/3,600,000) kwh_th = 0.0116222222 kwh_th
10 kcal = 10 kcal ÷ 860.42065009560224 = 0.0116222222 kwh_th
Summary
To convert Kilocalorie to Kilowatt-hour (thermal), multiply the value in kcal by the ratio of joules per kcal divided by joules per kwh_th. Equivalently: value_kwh_th = value_kcal × (4184 / 3600000). Numerically, 1 kcal equals 0.0011622222222222223 kwh_th.
Relationship context
You are converting between food / nutrition energy (calories) (Kilocalories) and electrical energy (watt-hours) (Kilowatt-hour (thermal)). All values are mapped through joules first. The numeric factor is 1.162222e-3.
