About Therm
A therm is a large US customary energy unit for natural gas (≈ 105.5 MJ here).
About Ton of Oil Equivalent
A ton of oil equivalent (toe) is a large industrial energy unit standardized at 41.868 GJ. It is common in energy policy and fuel-balance reporting.
How to convert therm to tons of oil equivalent
1 therm is equal to 0.00251995761111 ton of oil equivalent when both are expressed in joule-equivalents:
1 therm = (105,505,585.262 J ÷ 41,868,000,000 J) toe = 0.00251995761111 toe
Each therm is defined as 105,505,585.262 J and each ton of oil equivalent as 41,868,000,000 J in this tool, so one therm equals 105,505,585.262 ÷ 41,868,000,000 toe = 0.00251995761111 toe.
Let d(therm) be the numeric amount in Therm (therm), and d(toe) the amount in Ton of Oil Equivalent (toe). Then:
d(toe) = d(therm) × (105,505,585.262 / 41,868,000,000)
Equivalently, divide by how many therm fit into one toe (joules per toe divided by joules per therm):
d(toe) = d(therm) ÷ 396.83207193277968
Or: ton of oil equivalent = therm ÷ 396.83207193277968
Examples
Example #1: Convert 1 therm to ton of oil equivalent
1 therm = 1 therm × (105,505,585.262/41,868,000,000) toe = 0.0025199576 toe
1 therm = 1 therm ÷ 396.83207193277968 = 0.0025199576 toe
Example #2: Convert 10 therm to ton of oil equivalent
10 therm = 10 therm × (105,505,585.262/41,868,000,000) toe = 0.0251995761 toe
10 therm = 10 therm ÷ 396.83207193277968 = 0.0251995761 toe
Summary
To convert Therm to Ton of Oil Equivalent, multiply the value in therm by the ratio of joules per therm divided by joules per toe. Equivalently: value_toe = value_therm × (105505585.262 / 41868000000). Numerically, 1 therm equals 0.002519957611111111 toe.
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 Ton of Oil Equivalent is 2.519958e-3 (1 therm = 0.002519957611111111 toe).
