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.
About Gigajoule
One gigajoule is 1,000,000,000 J. Utility-scale and fuel-system reporting commonly use GJ.
How to convert million btu (mmbtu, it) to gigajoules
1 million btu (mmbtu, it) is equal to 1.05505585262 gigajoule when both are expressed in joule-equivalents:
1 mmbtu = (1,055,055,852.62 J ÷ 1,000,000,000 J) gj = 1.05505585262 gj
Each million btu (mmbtu, it) is defined as 1,055,055,852.62 J and each gigajoule as 1,000,000,000 J in this tool, so one mmbtu equals 1,055,055,852.62 ÷ 1,000,000,000 gj = 1.05505585262 gj.
Let d(mmbtu) be the numeric amount in Million BTU (MMBtu, IT) (mmbtu), and d(gj) the amount in Gigajoule (gj). Then:
d(gj) = d(mmbtu) × (1,055,055,852.62 / 1,000,000,000)
Equivalently, divide by how many mmbtu fit into one gj (joules per gj divided by joules per mmbtu):
d(gj) = d(mmbtu) ÷ 0.94781712031332
Or: gigajoule = million btu (mmbtu, it) ÷ 0.94781712031332
Examples
Example #1: Convert 1 mmbtu to gigajoule
1 mmbtu = 1 mmbtu × (1,055,055,852.62/1,000,000,000) gj = 1.0550558526 gj
1 mmbtu = 1 mmbtu ÷ 0.94781712031332 = 1.0550558526 gj
Example #2: Convert 10 mmbtu to gigajoule
10 mmbtu = 10 mmbtu × (1,055,055,852.62/1,000,000,000) gj = 10.5505585262 gj
10 mmbtu = 10 mmbtu ÷ 0.94781712031332 = 10.5505585262 gj
Summary
To convert Million BTU (MMBtu, IT) to Gigajoule, multiply the value in mmbtu by the ratio of joules per mmbtu divided by joules per gj. Equivalently: value_gj = value_mmbtu × (1055055852.62 / 1000000000). Numerically, 1 mmbtu equals 1.05505585262 gj.
