How to convert therms to British thermal units
BTU = thm × 100000
Multiply the number of therms by 100000 to get British thermal units. Going the other way, divide by 100000 (or multiply by 0.00001).
One therm is exactly defined as 100000 British thermal units (to 12 significant figures), and one British thermal unit is 0.00001 therms.
Worked examples
- Convert 5 therms: 5 × 100000 = 500,000 500,000 British thermal units.
- Convert 12.5 therms: 12.5 × 100000 = 1,250,000 1,250,000 British thermal units.
- Convert 250 therms: 250 × 100000 = 25,000,000 25,000,000 British thermal units.
