## Formula

P = W ÷ t, or P = F × v.

- Time must be above zero.
- 1 mechanical horsepower = 745.7 W.
- F × v assumes force and velocity point the same way.
- P = W ÷ t, or P = F × v.
- Inputs used: Method, Work, Time, Force, Speed.

## Inputs

- Method
- Work
- Time
- Force
- Speed

## Worked example: 500 J in 10 s

Average power.
1. P = 500 ÷ 10 = 50 W.

## Common questions

### Metric or mechanical horsepower?

The breakdown uses mechanical (imperial) horsepower, 745.7 W. Metric horsepower is 735.5 W.

### Is this average or peak power?

Work ÷ time is average power over the period.

### How do I get power from torque and speed?

Use the shaft power calculator, which uses P = 2π × N × T.

### How do I use the Mechanical Power Calculator?

Enter the required values for Method, Work, Time, Force, Speed. The calculator applies the formula on this page and shows the main result with any supporting breakdown so you can check the arithmetic.

### What formula does the Mechanical Power Calculator use?

P = W ÷ t, or P = F × v. The visible formula section above lists the calculation path and the edge cases the page handles, so the result can be checked without relying on the form alone.

### Can the Mechanical Power Calculator be used for exact decisions?

Use it as a calculation aid, not as a substitute for checking the underlying rule, contract, policy, or professional advice that applies to your situation. When a result depends on local rules, personal details, prices, or dates, enter those values yourself and confirm them before acting.

## Limitations and assumptions

- Average power only.
- No efficiency losses.
- Force and velocity assumed aligned.
- Results are estimates for planning and learning. Real designs, installations and bids must be checked by a qualified, licensed professional against the codes that apply where you work.
- The result depends on the values you enter for this mechanical power calculator; it does not supply missing rates, rules, prices, dates, or assumptions for you.
