How to convert therms to British thermal units

BTU = thm × 99,976.1289775

To convert therms to British thermal units, multiply the number of therms by 99,976.1289775.

Example: 18 thm to BTU

  1. Start with the value in therms: 18 thm.
  2. Multiply by 99,976.1289775: 18 × 99,976.1289775 = 1,799,570.322.
  3. Result: 18 therms = 1,799,570.322 British thermal units.

Going the other way, 1 British thermal unit = 0.000010002388 therms, so to convert British thermal units back to therms you divide by the same number. See British thermal units to therms.
