How to convert million btu (mmbtu, it) to feet-pounds
1 million btu (mmbtu, it) is equal to 7.78169262e+8 feet-pound when both are expressed in joule-equivalents:
1 mmbtu = (1,055,055,852.62 J ÷ 1.3558179483314003 J) ftlb = 7.78169262e+8 ftlb
Each million btu (mmbtu, it) is defined as 1,055,055,852.62 J and each feet-pound as 1.3558179483314003 J in this tool, so one mmbtu equals 1,055,055,852.62 ÷ 1.3558179483314003 ftlb = 7.78169262e+8 ftlb.
Let d(mmbtu) be the numeric amount in Million BTU (MMBtu, IT) (mmbtu), and d(ftlb) the amount in Feet-Pound (ftlb). Then:
d(ftlb) = d(mmbtu) × (1,055,055,852.62 / 1.3558179483314003)
Equivalently, divide by how many mmbtu fit into one ftlb (joules per ftlb divided by joules per mmbtu):
d(ftlb) = d(mmbtu) ÷ 1.28506746e-9
Or: feet-pound = million btu (mmbtu, it) ÷ 1.28506746e-9
Examples
Example #1: Convert 1 mmbtu to feet-pound
1 mmbtu = 1 mmbtu × (1,055,055,852.62/1.3558179483314003) ftlb = 778169262.2660000324 ftlb
1 mmbtu = 1 mmbtu ÷ 1.28506746e-9 = 778169262.2660000324 ftlb
Example #2: Convert 10 mmbtu to feet-pound
10 mmbtu = 10 mmbtu × (1,055,055,852.62/1.3558179483314003) ftlb = 7781692622.6599998474 ftlb
10 mmbtu = 10 mmbtu ÷ 1.28506746e-9 = 7781692622.6599998474 ftlb
Summary
To convert Million BTU (MMBtu, IT) to Feet-Pound, multiply the value in mmbtu by the ratio of joules per mmbtu divided by joules per ftlb. Equivalently: value_ftlb = value_mmbtu × (1055055852.62 / 1.3558179483314003). Numerically, 1 mmbtu equals 778169262.265965 ftlb.
Relationship context
Both units are US / imperial engineering units (BTU, therm, ft·lb). Conversions use fixed joule factors, so results stay consistent with the definitions in this converter. The factor from Million BTU (MMBtu, IT) to Feet-Pound is 7.781693e+8 (1 mmbtu = 778169262.265965 ftlb).
