Formula Used in the Power Calculator
Basic Power Formula
Power = Work ÷ Time
P = W ÷ t
Formula Components
- Work (W): Can be in Joules (J) or calories (cal)
- Time (t): Can be in seconds, minutes, or hours
- Power (P): Usually expressed in Watts (W), horsepower (hp), or calories per second
Example Calculation
If 200 Joules of work is done in 10 seconds:
Power = 200 ÷ 10 = 20 W
This simple formula ensures accurate and consistent power calculations.
Power Calculation Examples
| Work Done | Time | Power |
|---|---|---|
| 100 J | 5 seconds | 20 W |
| 500 J | 10 seconds | 50 W |
| 1000 J | 20 seconds | 50 W |
| 200 J | 4 seconds | 50 W |
| 300 J | 6 seconds | 50 W |
Unit Conversion Examples
| Power (W) | Horsepower | cal/s |
|---|---|---|
| 50 W | 0.067 hp | 11.95 cal/s |
| 100 W | 0.134 hp | 23.91 cal/s |
| 200 W | 0.268 hp | 47.83 cal/s |
| 500 W | 0.671 hp | 119.58 cal/s |
