Converting 3 BTUs to joules results in approximately 3,159.3 joules. This conversion reflects the amount of energy 3 BTUs represent when expressed in joules, the standard SI unit for energy measurement.
Since 1 British Thermal Unit (BTU) equals about 1,055.06 joules, multiplying 3 by this factor gives the total energy in joules: 3 x 1,055.06 = 3,165.18 joules. Minor differences may occur due to rounding, but this is the precise conversion value.
Conversion Result
3 BTUs is approximately equal to 3,159.3 joules.

Conversion Formula
The formula to convert btus into joules multiplies the number of btus by 1,055.06, which is the energy in joules contained in one BTU. This works because the conversion factor directly relates the two units based on their energy equivalence. For example, converting 4 btus: 4 x 1,055.06 = 4,220.24 joules.
Conversion Example
- Suppose you want to convert 5 btus to joules:
- Step 1: Take the value in btus, which is 5.
- Step 2: Multiply by 1,055.06 (the conversion factor): 5 x 1,055.06 = 5,275.3.
- Step 3: The result is 5,275.3 joules.
- Convert 2.5 btus to joules:
- Step 1: Use 2.5 as the value in btus.
- Step 2: Multiply by 1,055.06: 2.5 x 1,055.06 = 2,637.65.
- Step 3: The answer is 2,637.65 joules.
