Converting 3 btus to joules results in approximately 12559.2 joules.
This conversion is based on the fact that 1 British thermal unit (btu) equals about 4184 joules. Therefore, multiplying 3 btus by 4184 gives us the amount of energy in joules. In this case, 3 btus multiply by 4184 joules per btu equals 12552 joules, rounded to four decimal places it’s 12559.2 joules.
Introduction to BTUs and Joules
BTUs, short for British thermal units, are units used to measure energy especially in heating and cooling systems. Joules, on the other hand, are SI units that quantify energy, work, or heat. Understanding how they relate helps in converting energy measurements across different systems.

Conversion Formula
The formula to convert btus into joules is: Joules = BTUs × 4184. This works because each btu equals 4184 joules, so multiplying the number of btus by this factor gives the total energy in joules. For example, converting 5 btus: 5 × 4184 = 20920 joules.
Conversion Example
- Suppose you want convert 7 btus to joules:
- Step 1: Take the value 7 btus.
- Step 2: Multiply 7 by 4184 (since 1 btu = 4184 joules), so 7 × 4184 = 29288.
- Step 3: The energy in joules is 29288.
- Convert 10 btus to joules:
- Step 1: Start with 10 btus.
- Step 2: Multiply 10 by 4184, resulting in 41840.
- Step 3: The answer is 41840 joules.
- Convert 1.5 btus to joules:
- Step 1: Use 1.5 btus.
- Step 2: Multiply 1.5 by 4184, giving 6276.
- Step 3: The energy equals 6276 joules.
