Work and Power Calculator
Calculate work, average power, force or displacement with selectable units.
A QUICK WALKTHROUGH
How to use this tool
- Choose the unknown, then enter the known values and their units.
- Calculate
- Constant force: W = Fd cos θ. Average power: P = W/t. Signed values are preserved. θ is the angle between force and displacement. A zero denominator or |cos θ| < 0.0001 cannot be used to solve force or displacement. Time must be positive.
Formulas and units
Constant force: W = Fd cos θ. Average power: P = W/t. Signed values are preserved. θ is the angle between force and displacement. A zero denominator or |cos θ| < 0.0001 cannot be used to solve force or displacement. Time must be positive. F = W/(d cos θ); d = W/(F cos θ). kcal = 4184 J; hp = 745.6998715822702 W.

GOOD TO KNOW
Common questions
What does a negative result mean?
Negative work means the force component opposes displacement. Negative force or displacement represents direction relative to the chosen axis. Power follows the sign of work.
