About Therm
A therm is a large US customary energy unit for natural gas (≈ 105.5 MJ here).
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.
How to convert therm to watt hours
1 therm is equal to 29307.10701722222075 watt hour when both are expressed in joule-equivalents:
1 therm = (105,505,585.262 J ÷ 3,600 J) wh = 29307.10701722222075 wh
Each therm is defined as 105,505,585.262 J and each watt hour as 3,600 J in this tool, so one therm equals 105,505,585.262 ÷ 3,600 wh = 29307.10701722222075 wh.
Let d(therm) be the numeric amount in Therm (therm), and d(wh) the amount in Watt Hour (wh). Then:
d(wh) = d(therm) × (105,505,585.262 / 3,600)
Equivalently, divide by how many therm fit into one wh (joules per wh divided by joules per therm):
d(wh) = d(therm) ÷ 0.00003412141633
Or: watt hour = therm ÷ 0.00003412141633
Examples
Example #1: Convert 1 therm to watt hour
1 therm = 1 therm × (105,505,585.262/3,600) wh = 29307.1070172 wh
1 therm = 1 therm ÷ 0.00003412141633 = 29307.1070172 wh
Example #2: Convert 10 therm to watt hour
10 therm = 10 therm × (105,505,585.262/3,600) wh = 293071.070172 wh
10 therm = 10 therm ÷ 0.00003412141633 = 293071.070172 wh
Summary
To convert Therm to Watt Hour, multiply the value in therm by the ratio of joules per therm divided by joules per wh. Equivalently: value_wh = value_therm × (105505585.262 / 3600). Numerically, 1 therm equals 29307.10701722222 wh.
Relationship context
You are converting between US / imperial engineering units (BTU, therm, ft·lb) (Therm) and electrical energy (watt-hours) (Watt Hours). All values are mapped through joules first. The numeric factor is 2.930711e+4.
