  • 1 British thermal unit = 0.000010002388 therms
  • 1 therm = 99,976.12898 British thermal units
  • Formula: thm = BTU ÷ 99,976.1289775

1 British thermal unit = 0.000010002388 therms

How to convert British thermal units to therms

thm = BTU ÷ 99,976.1289775

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

Example: 18 BTU to thm

  1. Start with the value in British thermal units: 18 BTU.
  2. Divide by 99,976.1289775: 18 ÷ 99,976.1289775 = 0.000180042978.
  3. Result: 18 British thermal units = 0.000180042978 therms.

Going the other way, 1 therm = 99,976.1289775 British thermal units, so to convert therms back to British thermal units you multiply by the same number. See therms to British thermal units.
