Conversion Formula
The formula to convert BTU to joules multiplies the number of BTUs by 1055.05585262, the exact value of 1 BTU in joules. For example, if you want to convert 2 BTUs, you do 2 x 1055.05585262, resulting in 2110.11 joules. This works because the BTU is a fixed energy measurement and the multiplication scales it accordingly.
Conversion Example
- Convert 2 BTUs:
- Multiply 2 by 1055.05585262
- 2 x 1055.05585262 = 2110.11170524
- Result: approximately 2110.11 joules
- Convert 0.5 BTUs:
- Multiply 0.5 by 1055.05585262
- 0.5 x 1055.05585262 = 527.52792631
- Result: approximately 527.53 joules
- Convert 10 BTUs:
- Multiply 10 by 1055.05585262
- 10 x 1055.05585262 = 10550.5585262
- Result: approximately 10550.56 joules
