Energy
Convert kilojoule (kJ) to British thermal unit (BTU). Energy is the capacity to do work or transfer heat — the currency of every heat and material balance.
1 kJ = 0.9478171 BTU
To convert kilojoule to British thermal unit, multiply the kJ value by 0.9478171. To go the other way, divide by 0.9478171 (or multiply by 1.055056).
| kJ | BTU |
|---|---|
| 1 | 0.9478171 |
| 2 | 1.895634 |
| 5 | 4.739086 |
| 10 | 9.478171 |
| 25 | 23.69543 |
| 50 | 47.39086 |
| 100 | 94.78171 |
| 250 | 236.9543 |
| 500 | 473.9086 |
| 1000 | 947.8171 |
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 3600 kJ is 3412.142 BTU.
Multiply the value in kJ by 0.9478171 to get BTU. For example, 10 kJ = 9.478171 BTU.
1 kJ equals 0.9478171 BTU.
