About Therm
A therm is a large US customary energy unit for natural gas (≈ 105.5 MJ here).
About British Thermal Unit
The British thermal unit used here is the IT BTU: ≈ 1,055.056 J. It appears in HVAC, heating equipment, and US engineering data.
How to convert therm to british thermal units
1 therm is equal to 100000 british thermal unit when both are expressed in joule-equivalents:
1 therm = (105,505,585.262 J ÷ 1,055.05585262 J) btu = 100000 btu
Each therm is defined as 105,505,585.262 J and each british thermal unit as 1,055.05585262 J in this tool, so one therm equals 105,505,585.262 ÷ 1,055.05585262 btu = 100000 btu.
Let d(therm) be the numeric amount in Therm (therm), and d(btu) the amount in British Thermal Unit (btu). Then:
d(btu) = d(therm) × (105,505,585.262 / 1,055.05585262)
Equivalently, divide by how many therm fit into one btu (joules per btu divided by joules per therm):
d(btu) = d(therm) ÷ 0.00001
Or: british thermal unit = therm ÷ 0.00001
Examples
Example #1: Convert 1 therm to british thermal unit
1 therm = 1 therm × (105,505,585.262/1,055.05585262) btu = 100000 btu
1 therm = 1 therm ÷ 0.00001 = 100000 btu
Example #2: Convert 10 therm to british thermal unit
10 therm = 10 therm × (105,505,585.262/1,055.05585262) btu = 1000000 btu
10 therm = 10 therm ÷ 0.00001 = 1000000 btu
Summary
To convert Therm to British Thermal Unit, multiply the value in therm by the ratio of joules per therm divided by joules per btu. Equivalently: value_btu = value_therm × (105505585.262 / 1055.05585262). Numerically, 1 therm equals 100000 btu.
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 British Thermal Unit is 1.000000e+5 (1 therm = 100000 btu).
