About Megajoule
One megajoule is 1,000,000 J. It is common in fuel-content and engineering thermal calculations.
About British Thermal Unit
The British thermal unit used here is the IT BTU: ≈ 1,055.056 J. It appears in HVAC, heating equipment, and US engineering data.
How to convert megajoules to british thermal units
1 megajoule is equal to 947.81712031331722 british thermal unit when both are expressed in joule-equivalents:
1 mj = (1,000,000 J ÷ 1,055.05585262 J) btu = 947.81712031331722 btu
Each megajoule is defined as 1,000,000 J and each british thermal unit as 1,055.05585262 J in this tool, so one mj equals 1,000,000 ÷ 1,055.05585262 btu = 947.81712031331722 btu.
Let d(mj) be the numeric amount in Megajoule (mj), and d(btu) the amount in British Thermal Unit (btu). Then:
d(btu) = d(mj) × (1,000,000 / 1,055.05585262)
Equivalently, divide by how many mj fit into one btu (joules per btu divided by joules per mj):
d(btu) = d(mj) ÷ 0.00105505585262
Or: british thermal unit = megajoule ÷ 0.00105505585262
Examples
Example #1: Convert 1 mj to british thermal unit
1 mj = 1 mj × (1,000,000/1,055.05585262) btu = 947.817120313 btu
1 mj = 1 mj ÷ 0.00105505585262 = 947.817120313 btu
Example #2: Convert 10 mj to british thermal unit
10 mj = 10 mj × (1,000,000/1,055.05585262) btu = 9478.17120313 btu
10 mj = 10 mj ÷ 0.00105505585262 = 9478.17120313 btu
Summary
To convert Megajoule to British Thermal Unit, multiply the value in mj by the ratio of joules per mj divided by joules per btu. Equivalently: value_btu = value_mj × (1000000 / 1055.05585262). Numerically, 1 mj equals 947.8171203133172 btu.
Relationship context
You are converting between SI energy (joules) (Megajoules) and US / imperial engineering units (BTU, therm, ft·lb) (British Thermal Units). All values are mapped through joules first. The numeric factor is 9.478171e+2.
