Power relationships

Mechanical: P = Work ÷ Time or P = Force × Velocity. Electrical: P = Voltage × Current.

Pick the formula variant you need—mechanical or electrical.
Enter the inputs such as work and time or voltage and current.
Review power in watts with conversions to kilowatts and horsepower where applicable.

Example

Input: Electrical mode: Voltage = 230 V, Current = 8.5 A

Output: Power ≈ 1,955 W (≈ 1.96 kW, ≈ 2.62 hp)

Can I calculate power factor here?

Use the dedicated Power Factor calculator for AC systems—it handles apparent versus real power directly.

Does mechanical mode accept average force?

Yes. Provide the average force and velocity to estimate power for constant-speed motion.
