Power Calculator

Find power from work done over time.

Calculated Output

Power (W) 500

Power (hp) 0.6705

Formula: P = work ÷ time

Step-by-Step Breakdown

1. Values used:

2. Work / energy = 5,000 J

3. Time = 10

5. Power = Work / energy / Time = 5,000 / 10 = 500W

6. Power = 0.6705hp

The math behind it

P = work ÷ time. 1 watt = 1 joule per second; 1 hp ≈ 745.7 W.

5,000 J in 10 s → 500 W.
