About Gigajoule
One gigajoule is 1,000,000,000 J. Utility-scale and fuel-system reporting commonly use GJ.
About Million BTU (MMBtu, IT)
MMBtu means one million IT BTU: 1,000,000 × 1,055.05585262 J. It is widely used in gas and thermal energy markets.
How to convert gigajoules to million btu (mmbtu, it)
1 gigajoule is equal to 0.94781712031332 million btu (mmbtu, it) when both are expressed in joule-equivalents:
1 gj = (1,000,000,000 J ÷ 1,055,055,852.62 J) mmbtu = 0.94781712031332 mmbtu
Each gigajoule is defined as 1,000,000,000 J and each million btu (mmbtu, it) as 1,055,055,852.62 J in this tool, so one gj equals 1,000,000,000 ÷ 1,055,055,852.62 mmbtu = 0.94781712031332 mmbtu.
Let d(gj) be the numeric amount in Gigajoule (gj), and d(mmbtu) the amount in Million BTU (MMBtu, IT) (mmbtu). Then:
d(mmbtu) = d(gj) × (1,000,000,000 / 1,055,055,852.62)
Equivalently, divide by how many gj fit into one mmbtu (joules per mmbtu divided by joules per gj):
d(mmbtu) = d(gj) ÷ 1.05505585262
Or: million btu (mmbtu, it) = gigajoule ÷ 1.05505585262
Examples
Example #1: Convert 1 gj to million btu (mmbtu, it)
1 gj = 1 gj × (1,000,000,000/1,055,055,852.62) mmbtu = 0.9478171203 mmbtu
1 gj = 1 gj ÷ 1.05505585262 = 0.9478171203 mmbtu
Example #2: Convert 10 gj to million btu (mmbtu, it)
10 gj = 10 gj × (1,000,000,000/1,055,055,852.62) mmbtu = 9.4781712031 mmbtu
10 gj = 10 gj ÷ 1.05505585262 = 9.4781712031 mmbtu
Summary
To convert Gigajoule to Million BTU (MMBtu, IT), multiply the value in gj by the ratio of joules per gj divided by joules per mmbtu. Equivalently: value_mmbtu = value_gj × (1000000000 / 1055055852.62). Numerically, 1 gj equals 0.9478171203133172 mmbtu.
Relationship context
You are converting between SI energy (joules) (Gigajoules) and US / imperial engineering units (BTU, therm, ft·lb) (Million BTU (MMBtu, IT)). All values are mapped through joules first. The numeric factor is 9.478171e-1.
