What this tool does
Work is force times distance; power is the same work divided by how long it took. Doing a job twice as fast needs twice the power even though the work is identical, which is the whole reason motors are rated in watts.
Formula
W = F × d , P = W ÷ t
Variables

Limitations
- The formula assumes ideal conditions: no friction losses, no air resistance and no efficiency losses unless you enter them.
- Mixing units is the most common source of error. Convert every input to the units shown next to each field before calculating.
