About Therm
A therm is a large US customary energy unit for natural gas (≈ 105.5 MJ here).
About Feet-Pound
The feet-pound is a mechanical work unit common in US torque and ballistics contexts.
How to convert therm to feet-pounds
1 therm is equal to 7.78169262e+7 feet-pound when both are expressed in joule-equivalents:
1 therm = (105,505,585.262 J ÷ 1.3558179483314003 J) ftlb = 7.78169262e+7 ftlb
Each therm is defined as 105,505,585.262 J and each feet-pound as 1.3558179483314003 J in this tool, so one therm equals 105,505,585.262 ÷ 1.3558179483314003 ftlb = 7.78169262e+7 ftlb.
Let d(therm) be the numeric amount in Therm (therm), and d(ftlb) the amount in Feet-Pound (ftlb). Then:
d(ftlb) = d(therm) × (105,505,585.262 / 1.3558179483314003)
Equivalently, divide by how many therm fit into one ftlb (joules per ftlb divided by joules per therm):
d(ftlb) = d(therm) ÷ 1.28506746e-8
Or: feet-pound = therm ÷ 1.28506746e-8
Examples
Example #1: Convert 1 therm to feet-pound
1 therm = 1 therm × (105,505,585.262/1.3558179483314003) ftlb = 77816926.2266000062 ftlb
1 therm = 1 therm ÷ 1.28506746e-8 = 77816926.2266000062 ftlb
Example #2: Convert 10 therm to feet-pound
10 therm = 10 therm × (105,505,585.262/1.3558179483314003) ftlb = 778169262.2660000324 ftlb
10 therm = 10 therm ÷ 1.28506746e-8 = 778169262.2660000324 ftlb
Summary
To convert Therm to Feet-Pound, multiply the value in therm by the ratio of joules per therm divided by joules per ftlb. Equivalently: value_ftlb = value_therm × (105505585.262 / 1.3558179483314003). Numerically, 1 therm equals 77816926.22659649 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 Therm to Feet-Pound is 7.781693e+7 (1 therm = 77816926.22659649 ftlb).
