About Therm
A therm is a large US customary energy unit for natural gas (≈ 105.5 MJ here).
About Gigajoule
One gigajoule is 1,000,000,000 J. Utility-scale and fuel-system reporting commonly use GJ.
How to convert therm to gigajoules
1 therm is equal to 0.105505585262 gigajoule when both are expressed in joule-equivalents:
1 therm = (105,505,585.262 J ÷ 1,000,000,000 J) gj = 0.105505585262 gj
Each therm is defined as 105,505,585.262 J and each gigajoule as 1,000,000,000 J in this tool, so one therm equals 105,505,585.262 ÷ 1,000,000,000 gj = 0.105505585262 gj.
Let d(therm) be the numeric amount in Therm (therm), and d(gj) the amount in Gigajoule (gj). Then:
d(gj) = d(therm) × (105,505,585.262 / 1,000,000,000)
Equivalently, divide by how many therm fit into one gj (joules per gj divided by joules per therm):
d(gj) = d(therm) ÷ 9.47817120313317
Or: gigajoule = therm ÷ 9.47817120313317
Examples
Example #1: Convert 1 therm to gigajoule
1 therm = 1 therm × (105,505,585.262/1,000,000,000) gj = 0.1055055853 gj
1 therm = 1 therm ÷ 9.47817120313317 = 0.1055055853 gj
Example #2: Convert 10 therm to gigajoule
10 therm = 10 therm × (105,505,585.262/1,000,000,000) gj = 1.0550558526 gj
10 therm = 10 therm ÷ 9.47817120313317 = 1.0550558526 gj
Summary
To convert Therm to Gigajoule, multiply the value in therm by the ratio of joules per therm divided by joules per gj. Equivalently: value_gj = value_therm × (105505585.262 / 1000000000). Numerically, 1 therm equals 0.10550558526199999 gj.
Relationship context
You are converting between US / imperial engineering units (BTU, therm, ft·lb) (Therm) and SI energy (joules) (Gigajoules). All values are mapped through joules first. The numeric factor is 1.055056e-1.
