Energy
Convert British thermal unit (BTU) to megajoule (MJ). Energy is the capacity to do work or transfer heat — the currency of every heat and material balance.
1 BTU = 0.001055056 MJ
To convert British thermal unit to megajoule, multiply the BTU value by 0.001055056. To go the other way, divide by 0.001055056 (or multiply by 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 3412.142 BTU is 3.6 MJ.
Multiply the value in BTU by 0.001055056 to get MJ. For example, 10 BTU = 0.01055056 MJ.
1 BTU equals 0.001055056 MJ.
