About Calorie
The small calorie (cal) is 4.184 J in this converter (thermochemical). Do not confuse with the dietary kilocalorie (kcal).
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 calories to tons of oil equivalent
1 calorie is equal to 9.99331231e-11 ton of oil equivalent when both are expressed in joule-equivalents:
1 cal = (4.184 J ÷ 41,868,000,000 J) toe = 9.99331231e-11 toe
Each calorie is defined as 4.184 J and each ton of oil equivalent as 41,868,000,000 J in this tool, so one cal equals 4.184 ÷ 41,868,000,000 toe = 9.99331231e-11 toe.
Let d(cal) be the numeric amount in Calorie (cal), and d(toe) the amount in Ton of Oil Equivalent (toe). Then:
d(toe) = d(cal) × (4.184 / 41,868,000,000)
Equivalently, divide by how many cal fit into one toe (joules per toe divided by joules per cal):
d(toe) = d(cal) ÷ 1.00066922e+10
Or: ton of oil equivalent = calorie ÷ 1.00066922e+10
Examples
Example #1: Convert 1 cal to ton of oil equivalent
1 cal = 1 cal × (4.184/41,868,000,000) toe = 0.0000000001 toe
1 cal = 1 cal ÷ 1.00066922e+10 = 0.0000000001 toe
Example #2: Convert 10 cal to ton of oil equivalent
10 cal = 10 cal × (4.184/41,868,000,000) toe = 0.000000001 toe
10 cal = 10 cal ÷ 1.00066922e+10 = 0.000000001 toe
Summary
To convert Calorie to Ton of Oil Equivalent, multiply the value in cal by the ratio of joules per cal divided by joules per toe. Equivalently: value_toe = value_cal × (4.184 / 41868000000). Numerically, 1 cal equals 9.993312314894431e-11 toe.
Relationship context
You are converting between food / nutrition energy (calories) (Calories) and US / imperial engineering units (BTU, therm, ft·lb) (Tons of Oil Equivalent). All values are mapped through joules first. The numeric factor is 9.993312e-11.
