About Joule
The joule is the SI unit of energy. All other units here are converted through fixed joule equivalents.
About Therm
A therm is a large US customary energy unit for natural gas (≈ 105.5 MJ here).
How to convert joules to therm
1 joule is equal to 9.47817120e-9 therm when both are expressed in joule-equivalents:
1 j = (1 J ÷ 105,505,585.262 J) therm = 9.47817120e-9 therm
Each joule is defined as 1 J and each therm as 105,505,585.262 J in this tool, so one j equals 1 ÷ 105,505,585.262 therm = 9.47817120e-9 therm.
Let d(j) be the numeric amount in Joule (j), and d(therm) the amount in Therm (therm). Then:
d(therm) = d(j) × (1 / 105,505,585.262)
Equivalently, divide by how many j fit into one therm (joules per therm divided by joules per j):
d(therm) = d(j) ÷ 1.05505585e+8
Or: therm = joule ÷ 1.05505585e+8
Examples
Example #1: Convert 1 j to therm
1 j = 1 j × (1/105,505,585.262) therm = 0.0000000095 therm
1 j = 1 j ÷ 1.05505585e+8 = 0.0000000095 therm
Example #2: Convert 10 j to therm
10 j = 10 j × (1/105,505,585.262) therm = 0.0000000948 therm
10 j = 10 j ÷ 1.05505585e+8 = 0.0000000948 therm
Summary
To convert Joule to Therm, multiply the value in j by the ratio of joules per j divided by joules per therm. Equivalently: value_therm = value_j × (1 / 105505585.262). Numerically, 1 j equals 9.478171203133172e-9 therm.
Relationship context
You are converting between SI energy (joules) (Joules) and US / imperial engineering units (BTU, therm, ft·lb) (Therm). All values are mapped through joules first. The numeric factor is 9.478171e-9.
