What this energy conversion is for

Use this page when a measurement is written in therms and the next step needs kilowatt-hours. The number stays blank until you press Calculate, so a half-typed entry is never mistaken for the answer.

The factor

Multiply by the factor: 1 therm = 29.30011111 kilowatt-hours.

A worked example

10 therms are 293.00111111 kilowatt-hours. Multiply the result by the reverse factor if you want the original number back.

How to check it

Write the factor down, do the multiply on paper, and compare it with the result card. If you change a sentence on this page, edit the HTML file and reload. The form and this note live in the same file.

The reverse conversion is kilowatt-hours to therms. A nearby pair in the same units is electronvolts to kilowatt-hours. When the converted number is the input to a job, continue with the what the power costs.
