About Kilowatt Hour

One kilowatt-hour is the energy from 1 kW of power for one hour: 1 kWh = 3,600,000 J. Utility bills and battery specs often use kWh.

About Therm

A therm is a large US customary energy unit for natural gas (≈ 105.5 MJ here).

How to convert kilowatt hours to therm

1 kilowatt hour is equal to 0.03412141633128 therm when both are expressed in joule-equivalents:

1 kwh = (3,600,000 J ÷ 105,505,585.262 J) therm = 0.03412141633128 therm

Each kilowatt hour is defined as 3,600,000 J and each therm as 105,505,585.262 J in this tool, so one kwh equals 3,600,000 ÷ 105,505,585.262 therm = 0.03412141633128 therm.

Let d(kwh) be the numeric amount in Kilowatt Hour (kwh), and d(therm) the amount in Therm (therm). Then:

d(therm) = d(kwh) × (3,600,000 / 105,505,585.262)

Equivalently, divide by how many kwh fit into one therm (joules per therm divided by joules per kwh):

d(therm) = d(kwh) ÷ 29.30710701722222

Or: therm = kilowatt hour ÷ 29.30710701722222

Examples

Example #1: Convert 1 kwh to therm

1 kwh = 1 kwh × (3,600,000/105,505,585.262) therm = 0.0341214163 therm

1 kwh = 1 kwh ÷ 29.30710701722222 = 0.0341214163 therm

Example #2: Convert 10 kwh to therm

10 kwh = 10 kwh × (3,600,000/105,505,585.262) therm = 0.3412141633 therm

10 kwh = 10 kwh ÷ 29.30710701722222 = 0.3412141633 therm

Summary

To convert Kilowatt Hour to Therm, multiply the value in kwh by the ratio of joules per kwh divided by joules per therm. Equivalently: value_therm = value_kwh × (3600000 / 105505585.262). Numerically, 1 kwh equals 0.03412141633127942 therm.

Relationship context

You are converting between electrical energy (watt-hours) (Kilowatt Hours) and US / imperial engineering units (BTU, therm, ft·lb) (Therm). All values are mapped through joules first. The numeric factor is 3.412142e-2.
