Conversion Formula
The conversion from kilowatts (kW) to BTU involves multiplying the energy value in kW by 3412.14, since 1 kW equals 3412.14 BTU/hr. This works because power units (kW) are converted to heat energy (BTU) by applying this factor, which aligns with the energy rate conversion. For example, 10 kW times 3412.14 equals 34,121.4 BTU, showing how the formula scales with different values.
Conversion Example
- Convert 10 kW:
- Multiply 10 by 3412.14
- 10 x 3412.14 = 34,121.4 BTU
- Convert 25 kW:
- Multiply 25 by 3412.14
- 25 x 3412.14 = 85,303.5 BTU
- Convert 50 kW:
- Multiply 50 by 3412.14
- 50 x 3412.14 = 170,607 BTU
- Convert 100 kW:
- Multiply 100 by 3412.14
- 100 x 3412.14 = 341,214 BTU
- Convert 5 kW:
- Multiply 5 by 3412.14
- 5 x 3412.14 = 17,060.7 BTU
