Energy
Convert calorie (cal) to kilowatt-hour (kWh). Energy is the capacity to do work or transfer heat — the currency of every heat and material balance.
1 cal = 1.1622e-6 kWh
To convert calorie to kilowatt-hour, multiply the cal value by 1.1622e-6. To go the other way, divide by 1.1622e-6 (or multiply by 860420.7).
| cal | kWh |
|---|---|
| 1 | 1.1622e-6 |
| 2 | 2.3244e-6 |
| 5 | 5.8111e-6 |
| 10 | 1.1622e-5 |
| 25 | 2.9056e-5 |
| 50 | 5.8111e-5 |

Heat duties integrate to energy in kJ, MJ, or BTU; utilities are billed in kWh or MMBTU.
A calorie, a BTU, and a joule are all energy — keep the conversion factors handy when a spec mixes them.
Worked example. A energy of 860420.7 cal is 1 kWh.
Multiply the value in cal by 1.1622e-6 to get kWh. For example, 10 cal = 1.1622e-5 kWh.
1 cal equals 1.1622e-6 kWh.
