Conversion Formula
The formula to convert btus to joules multiplies the number of btus by 4184, because 1 btu equals 4184 joules. For example, if you have 3 btus, multiply 3 by 4184 to get the energy in joules:
- 3 btus x 4184 = 12552 joules
This works because the conversion factor directly relates the two units, allowing energy measured in btus to be expressed in joules, which is the standard SI unit of energy.
Conversion Example
- Convert 5 btus to joules:
- Multiply 5 by 4184:
- 5 x 4184 = 20920 joules
- Convert 10 btus to joules:
- 10 x 4184 = 41840 joules
- Convert 0.5 btus to joules:
- 0.5 x 4184 = 2092 joules
- Convert 7.2 btus to joules:
- 7.2 x 4184 = 30124.8 joules
