About Watt Hour
One watt-hour is 3,600 J—the energy from 1 W for one hour. Common for small batteries and device ratings.
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 watt hours to tons of oil equivalent
1 watt hour is equal to 8.59845228e-8 ton of oil equivalent when both are expressed in joule-equivalents:
1 wh = (3,600 J ÷ 41,868,000,000 J) toe = 8.59845228e-8 toe
Each watt hour is defined as 3,600 J and each ton of oil equivalent as 41,868,000,000 J in this tool, so one wh equals 3,600 ÷ 41,868,000,000 toe = 8.59845228e-8 toe.
Let d(wh) be the numeric amount in Watt Hour (wh), and d(toe) the amount in Ton of Oil Equivalent (toe). Then:
d(toe) = d(wh) × (3,600 / 41,868,000,000)
Equivalently, divide by how many wh fit into one toe (joules per toe divided by joules per wh):
d(toe) = d(wh) ÷ 1.16300000e+7
Or: ton of oil equivalent = watt hour ÷ 1.16300000e+7
Examples
Example #1: Convert 1 wh to ton of oil equivalent
1 wh = 1 wh × (3,600/41,868,000,000) toe = 0.000000086 toe
1 wh = 1 wh ÷ 1.16300000e+7 = 0.000000086 toe
Example #2: Convert 10 wh to ton of oil equivalent
10 wh = 10 wh × (3,600/41,868,000,000) toe = 0.0000008598 toe
10 wh = 10 wh ÷ 1.16300000e+7 = 0.0000008598 toe
Summary
To convert Watt Hour to Ton of Oil Equivalent, multiply the value in wh by the ratio of joules per wh divided by joules per toe. Equivalently: value_toe = value_wh × (3600 / 41868000000). Numerically, 1 wh equals 8.598452278589854e-8 toe.
Relationship context
You are converting between electrical energy (watt-hours) (Watt Hours) and US / imperial engineering units (BTU, therm, ft·lb) (Tons of Oil Equivalent). All values are mapped through joules first. The numeric factor is 8.598452e-8.
