Energy
Convert megajoule (MJ) to British thermal unit (BTU). Energy is the capacity to do work or transfer heat — the currency of every heat and material balance.
1 MJ = 947.8171 BTU
To convert megajoule to British thermal unit, multiply the MJ value by 947.8171. To go the other way, divide by 947.8171 (or multiply by 0.001055056).
| MJ | BTU |
|---|---|
| 1 | 947.8171 |
| 2 | 1895.634 |
| 5 | 4739.086 |
| 10 | 9478.171 |
| 25 | 23695.43 |
| 50 | 47390.86 |
| 100 | 94781.71 |
| 250 | 236954.3 |
| 500 | 473908.6 |
| 1000 | 947817.1 |
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 3.6 MJ is 3412.142 BTU.
Multiply the value in MJ by 947.8171 to get BTU. For example, 10 MJ = 9478.171 BTU.
1 MJ equals 947.8171 BTU.
