Understanding Power Measurements
Power conversions are essential for various applications, from electrical engineering and physics to everyday energy consumption and environmental science. Understanding power conversions ensures accurate and consistent results across different measurement systems.
Common Power Units
Metric Units
- Watt (W)
- Kilowatt (kW)
- Megawatt (MW)
- Gigawatt (GW)
Other Units
- Horsepower (hp)
- British Thermal Unit per Hour (BTU/h)
- Foot-pound per Second (ft·lb/s)
- Calorie per Second (cal/s)
Common Applications
| Field | Measurement Types | Typical Uses |
|---|---|---|
| Electrical Engineering | Watts, Kilowatts | Power consumption, energy efficiency |
| Physics | Watts, Horsepower | Energy transfer, mechanical power |
| Automotive | Horsepower, Kilowatts | Engine power, vehicle performance |
| Environmental Science | Watts, Megawatts | Energy conservation, sustainability |
Conversion Tips
- Use a calculator for precise power conversions
- For quick estimates: 1 horsepower = 745.7 watts
- Remember that 1 kilowatt = 1000 watts
- For electrical power, use watts or kilowatts
- For mechanical power, use horsepower or foot-pounds per second
Power Conversions
| Conversion | Formula/Rule | Quick Answer |
|---|---|---|
| Watts to Horsepower | 1 hp = 745.7 W | Divide W by 745.7 |
| Horsepower to Watts | 1 W = 0.00134 hp | Multiply hp by 745.7 |
| Watts to Kilowatts | 1 kW = 1000 W | Divide W by 1000 |
| Kilowatts to Watts | 1 W = 0.001 kW | Multiply kW by 1000 |
| Watts to BTU/h | 1 BTU/h = 0.293 W | Divide W by 0.293 |
| BTU/h to Watts | 1 W = 3.412 BTU/h | Multiply BTU/h by 0.293 |
| Watts to Foot-pounds per Second | 1 ft·lb/s = 1.356 W | Divide W by 1.356 |
| Foot-pounds per Second to Watts | 1 W = 0.7376 ft·lb/s | Multiply ft·lb/s by 1.356 |
