What Is the Power Converter?
Power conversion calculates rates of work completion or energy transfer over time.
How Does the Power Converter Work?
Converts through Watts: 1 hp (mechanical) = 745.7 W, 1 kW = 1,000 W, 1 BTU/hr = 0.29307 W.
Power Converter Formula & Variables
The core mathematical equation utilized by this calculator is expressed as:
P_{\text{target}} = P_{\text{source}} \times \frac{\text{Factor}_{\text{source}}}{\text{Factor}_{\text{target}}}
Converts through the standard SI Watt (1 W = 1 J/s).
How to Use the Power Converter
- Enter the power number and select your source and destination units.
Step-by-Step Example Calculation
Convert 150 hp to kW
Input Values:
value:150
fromUnit:hp
toUnit:kw
Worked Steps: 150 mechanical horsepower equals approximately 111.85 kW.
Understanding Your Result
Shows engine horsepower output converted to electrical kilowatts and HVAC thermal ratings.
Factors That Affect the Result
- Mechanical imperial horsepower (745.7 W) vs metric horsepower PS (735.5 W).
When Should You Use This Calculator?
- Comparing electric vehicles to gasoline cars, sizing home generators, and buying HVAC air conditioning units.
Assumptions & Limitations
- Uses standard mechanical imperial horsepower (550 ft·lbf/s).
