Energy
Convert kilojoule (kJ) to million BTU (MMBTU). Energy is the capacity to do work or transfer heat — the currency of every heat and material balance.
1 kJ = 9.4782e-7 MMBTU
To convert kilojoule to million BTU, multiply the kJ value by 9.4782e-7. To go the other way, divide by 9.4782e-7 (or multiply by 1055056).
| kJ | MMBTU |
|---|---|
| 1 | 9.4782e-7 |

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 0.003412142 MMBTU.
Multiply the value in kJ by 9.4782e-7 to get MMBTU. For example, 10 kJ = 9.4782e-6 MMBTU.
1 kJ equals 9.4782e-7 MMBTU.
