What is a power converter?
Power measures the rate at which energy is transferred or converted. The SI unit is the watt (W). Other common units include horsepower (used for engines), kilowatts (electricity), and BTU/hour (HVAC systems).
Common uses for power conversion
- Electrical Engineering — Converting between watts, kilowatts, and megawatts
- Automotive — Comparing engine power in horsepower vs. kilowatts
- HVAC — Calculating heating/cooling capacity in BTU/hr and tons of refrigeration
- Solar Energy — Sizing solar panel systems in watts and kilowatts
- Industrial — Converting motor power ratings between different standards
All power units
- Watt (W)
- Milliwatt (mW)
- Kilowatt (kW)
- Megawatt (MW)
- Gigawatt (GW)
- Horsepower (British) (hp)
- Horsepower (Metric) (PS)
- BTU/hour (BTU/h)
- BTU/second (BTU/s)
- Foot-pound/minute (ft⋅lbf/min)
- Foot-pound/second (ft⋅lbf/s)
Tips for power conversion
- 1 horsepower ≈ 745.7 watts — a car with 200 HP produces about 149 kW
- 1 kW = 3,412 BTU/hr — useful for HVAC calculations
- A typical household uses about 30 kWh per day, or about 1.25 kW average power
