Energy
Convert kilowatt-hour (kWh) to British thermal unit (BTU). Energy is the capacity to do work or transfer heat — the currency of every heat and material balance.
1 kWh = 3412.142 BTU
To convert kilowatt-hour to British thermal unit, multiply the kWh value by 3412.142. To go the other way, divide by 3412.142 (or multiply by 0.0002930711).
| kWh | BTU |
|---|---|
| 1 | 3412.142 |
| 2 | 6824.283 |
| 5 | 17060.71 |
| 10 | 34121.42 |
| 25 | 85303.54 |
| 50 | 170607.1 |
| 100 | 341214.2 |
| 250 | 853035.4 |
| 500 | 1706071 |
| 1000 | 3412142 |
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.
