Joules to Therms Converter

1 joule (J) equals 9.4804343 × 10-9 therms (thm).

Quick answer

  • 1 joule = 9.4804343 × 10-9 therms
  • 1 therm = 105,480,400 joules
  • Formula: thm = J ÷ 105,480,400

1 joule = 9.4804343 × 10-9 therms

How to convert joules to therms

thm = J ÷ 105,480,400

To convert joules to therms, divide the number of joules by 105,480,400.

Example: 18 J to thm

  1. Start with the value in joules: 18 J.
  2. Divide by 105,480,400: 18 ÷ 105,480,400 = 1.7064782 × 10-7.
  3. Result: 18 joules = 1.7064782 × 10-7 therms.

Going the other way, 1 therm = 105,480,400 joules, so to convert therms back to joules you multiply by the same number. See therms to joules.
