Energy
Convert watt-hour (Wh) to British thermal unit (BTU). Energy is the capacity to do work or transfer heat — the currency of every heat and material balance.
1 Wh = 3.412142 BTU
To convert watt-hour to British thermal unit, multiply the Wh value by 3.412142. To go the other way, divide by 3.412142 (or multiply by 0.2930711).
| Wh | BTU |
|---|---|
| 1 | 3.412142 |
| 2 | 6.824283 |
| 5 | 17.06071 |
| 10 | 34.12142 |
| 25 | 85.30354 |
| 50 | 170.6071 |
| 100 | 341.2142 |
| 250 | 853.0354 |
| 500 | 1706.071 |
| 1000 | 3412.142 |
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 1000 Wh is 3412.142 BTU.
Multiply the value in Wh by 3.412142 to get BTU. For example, 10 Wh = 34.12142 BTU.
1 Wh equals 3.412142 BTU.
