How to convert British thermal units to joules
J = BTU × 1,055.05585262
To convert British thermal units to joules, multiply the number of British thermal units by 1,055.05585262.
Example: 42 BTU to J
- Start with the value in British thermal units: 42 BTU.
- Multiply by 1,055.05585262: 42 × 1,055.05585262 = 44,312.34581.
- Result: 42 British thermal units = 44,312.34581 joules.
Going the other way, 1 joule = 0.00094781712 British thermal units, so to convert joules back to British thermal units you divide by the same number. See joules to British thermal units.
