1 kilojoule (kJ) equals 0.947817120313 British thermal units (BTU).
Quick answer
- 1 kilojoule = 0.9478171203 British thermal units
- 1 British thermal unit = 1.055055853 kilojoules
- Formula: BTU = kJ × 0.947817120313
1 kilojoule = 0.9478171203 British thermal units
How to convert kilojoules to British thermal units
BTU = kJ × 0.947817120313
To convert kilojoules to British thermal units, multiply the number of kilojoules by 0.947817120313.
Example: 42 kJ to BTU
- Start with the value in kilojoules: 42 kJ.
- Multiply by 0.947817120313: 42 × 0.947817120313 = 39.80831905.
- Result: 42 kilojoules = 39.80831905 British thermal units.
Going the other way, 1 British thermal unit = 1.05505585262 kilojoules, so to convert British thermal units back to kilojoules you divide by the same number. See British thermal units to kilojoules.
