User Guide

Use this calculator to determine the power in watt, kilowatt or horsepower units, from the total energy transferred or work done for a given period of time.

Formula

The formula used by this calculator to determine the power from the work done and time taken is:

P = W / t

Symbols

• P = Power output
• W = Work done or energy transferred
• t = Time duration

Work (W)

This is the total energy transferred or work done.

Time (t)

This is the total elapsed time.

Power (P)

This is the rate at which energy is transferred.
