Power Calculator

Enter the change in work and change in time of an object or system to calculate the total power of that system.

Power, is the derivative of work with respect to time represented as:

P (Power) = dW/dt, where W is work and t is time.

In a simple equation, the power formula can look something like this:

Power (P) = (W1-W2)/(T1-T2), where W is work and t is time.

Power can also be described as the rate of transferring heat, which is synonymous with work. The international standard unit for power it joules per second (J/s). Unlike velocity, force, and acceleration, Power is a scalar quantity and has no direction.

In terms of electricity, the output power of an electric motor is the product of the torque and the velocity or in terms of light, it’s measured in watts.
