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 feet-pounds to million btu (mmbtu, it)
1 feet-pound is equal to 1.28506746e-9 million btu (mmbtu, it) when both are expressed in joule-equivalents:
1 ftlb = (1.3558179483314003 J ÷ 1,055,055,852.62 J) mmbtu = 1.28506746e-9 mmbtu
Each feet-pound is defined as 1.3558179483314003 J and each million btu (mmbtu, it) as 1,055,055,852.62 J in this tool, so one ftlb equals 1.3558179483314003 ÷ 1,055,055,852.62 mmbtu = 1.28506746e-9 mmbtu.
Let d(ftlb) be the numeric amount in Feet-Pound (ftlb), and d(mmbtu) the amount in Million BTU (MMBtu, IT) (mmbtu). Then:
d(mmbtu) = d(ftlb) × (1.3558179483314003 / 1,055,055,852.62)
Equivalently, divide by how many ftlb fit into one mmbtu (joules per mmbtu divided by joules per ftlb):
d(mmbtu) = d(ftlb) ÷ 7.78169262e+8
Or: million btu (mmbtu, it) = feet-pound ÷ 7.78169262e+8
Examples
Example #1: Convert 1 ftlb to million btu (mmbtu, it)
1 ftlb = 1 ftlb × (1.3558179483314003/1,055,055,852.62) mmbtu = 0.0000000013 mmbtu
1 ftlb = 1 ftlb ÷ 7.78169262e+8 = 0.0000000013 mmbtu
Example #2: Convert 10 ftlb to million btu (mmbtu, it)
10 ftlb = 10 ftlb × (1.3558179483314003/1,055,055,852.62) mmbtu = 0.0000000129 mmbtu
10 ftlb = 10 ftlb ÷ 7.78169262e+8 = 0.0000000129 mmbtu
Summary
To convert Feet-Pound to Million BTU (MMBtu, IT), multiply the value in ftlb by the ratio of joules per ftlb divided by joules per mmbtu. Equivalently: value_mmbtu = value_ftlb × (1.3558179483314003 / 1055055852.62). Numerically, 1 ftlb equals 1.2850674634565777e-9 mmbtu.
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 Feet-Pound to Million BTU (MMBtu, IT) is 1.285067e-9 (1 ftlb = 1.2850674634565777e-9 mmbtu).
