The BTU per Hour Calculator helps determine the energy consumption rate in British Thermal Units per hour (BTU/hr). This calculation is essential for heating, cooling, and power efficiency analysis.
Formula
The formula for calculating BTU per hour is:
BTU/hr = (W × 3.412141633) + (HP × 2544.433)
Where:
- W = Work done in watts
- HP = Horsepower
How to Use
- Input the work done in watts.
- Enter the horsepower value.
- Click the “Calculate” button to get the BTU/hr result.
Example
If you input:
- Work Done (W) = 1000
- Horsepower (HP) = 3
Calculation:
BTU/hr = (1000 × 3.412141633) + (3 × 2544.433)
BTU/hr = 3412.14 + 7633.30 = 11045.44 BTU/hr
