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.
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 british thermal units to tons of oil equivalent
1 british thermal unit is equal to 2.51995761e-8 ton of oil equivalent when both are expressed in joule-equivalents:
1 btu = (1,055.05585262 J ÷ 41,868,000,000 J) toe = 2.51995761e-8 toe
Each british thermal unit is defined as 1,055.05585262 J and each ton of oil equivalent as 41,868,000,000 J in this tool, so one btu equals 1,055.05585262 ÷ 41,868,000,000 toe = 2.51995761e-8 toe.
Let d(btu) be the numeric amount in British Thermal Unit (btu), and d(toe) the amount in Ton of Oil Equivalent (toe). Then:
d(toe) = d(btu) × (1,055.05585262 / 41,868,000,000)
Equivalently, divide by how many btu fit into one toe (joules per toe divided by joules per btu):
d(toe) = d(btu) ÷ 3.96832072e+7
Or: ton of oil equivalent = british thermal unit ÷ 3.96832072e+7
Examples
Example #1: Convert 1 btu to ton of oil equivalent
1 btu = 1 btu × (1,055.05585262/41,868,000,000) toe = 0.0000000252 toe
1 btu = 1 btu ÷ 3.96832072e+7 = 0.0000000252 toe
Example #2: Convert 10 btu to ton of oil equivalent
10 btu = 10 btu × (1,055.05585262/41,868,000,000) toe = 0.000000252 toe
10 btu = 10 btu ÷ 3.96832072e+7 = 0.000000252 toe
Summary
To convert British Thermal Unit to Ton of Oil Equivalent, multiply the value in btu by the ratio of joules per btu divided by joules per toe. Equivalently: value_toe = value_btu × (1055.05585262 / 41868000000). Numerically, 1 btu equals 2.519957611111111e-8 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 British Thermal Unit to Ton of Oil Equivalent is 2.519958e-8 (1 btu = 2.519957611111111e-8 toe).
