How to Use This Calculator

Enter work done (J) and time elapsed (s) to calculate power, or enter force (N) and velocity (m/s).
Review power in watts (W = J/s) and in horsepower.
Convert watts to kilowatts (divide by 1000) or to kWh (multiply by hours) for energy calculations.
Use for motor sizing, engine performance analysis, and energy consumption estimates.

How the result changes with Time

Time	Power
10,000	0.1 W
35,000	0.03 W
65,000	0.02 W
90,000	0.01 W

What each input means

Work: Work done in Joules.
Time: Time taken in seconds.
Force (Alternative): Force in Newtons (alternative calculation).
Velocity (Alternative): Velocity in m/s (alternative calculation).
