What Is the Power Calculator?
A power calculator works out how quickly work is done or energy is used.
How Does the Power Calculator Work?
It divides work by time, or multiplies force by velocity, then converts to other units.
Power Calculator Formula & Variables
The core mathematical equation utilized by this calculator is expressed as:
Power divides the work done by the time taken; the same rate equals force times velocity.
How to Use the Power Calculator
- Choose the method, enter the values and read the power in watts and related units.
Step-by-Step Example Calculation
1,000 J in 5 s
Input Values:
mode:work
workJ:1000
timeS:5
Worked Steps: That is 200 W, about 0.27 hp.
Understanding Your Result
The result is the power in watts, with kilowatts, horsepower and BTU/h.
Factors That Affect the Result
- The amount of work and the time taken, or the force and speed, set the power.
When Should You Use This Calculator?
- Use it for motors, appliances, exercise output and any work-rate problem.
Assumptions & Limitations
- Assumes the work or force is applied steadily over the interval.
