Energy
Convert million BTU (MMBTU) to kilojoule (kJ). Energy is the capacity to do work or transfer heat — the currency of every heat and material balance.
1 MMBTU = 1055056 kJ
To convert million BTU to kilojoule, multiply the MMBTU value by 1055056. To go the other way, divide by 1055056 (or multiply by 9.4782e-7).
| MMBTU | kJ |
|---|---|
| 1 | 1055056 |
| 2 | 2110112 |
| 5 | 5275279 |
| 10 | 1.0551e+7 |
| 25 | 2.6376e+7 |
| 50 | 5.2753e+7 |
| 100 | 1.0551e+8 |
| 250 | 2.6376e+8 |
| 500 | 5.2753e+8 |
| 1000 | 1.0551e+9 |
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 0.003412142 MMBTU is 3600 kJ.
Multiply the value in MMBTU by 1055056 to get kJ. For example, 10 MMBTU = 1.0551e+7 kJ.
1 MMBTU equals 1055056 kJ.
