Calculating your work done is straightforward once you know the Work formula and what each input means. This guide explains the method in plain language, walks through a manual calculation, and gives worked examples you can follow — then you can do it instantly with the Work Calculator.

What is Work?

The Work calculation tells you your work done from a few simple inputs. The figure you are solving for here is the work done.

The Work formula

The core formula is:

Work done = Force × Distance

Here is what each input means:

  • Force — a value measured in N. Example: 100 N.
  • Distance — a value measured in m. Example: 5 m.

How to calculate it step by step

  • Write down the force (for example, 100 N).
  • Write down the distance (for example, 5 m).
  • Apply the formula above to get your work done.
  • Double-check the result with the Work Calculator.

Worked examples

Example 1

Input / OutputValue
Force100 N
Distance5 m
Work done500.000

With force of 100 N and distance of 5 m, the work done works out to 500.000.

Example 2

With force of 200 N and distance of 5 m, the work done works out to 1,000.000.

ResultValue
Work done1,000.000

Example 3

With force of 50 N and distance of 5 m, the work done works out to 250.000.

ResultValue
Work done250.000

Tips for an accurate result

  • Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
  • Round only at the very end. Rounding inputs early can shift the final answer noticeably.
  • Re-run the numbers whenever an input changes, rather than estimating from an old result.

Prefer not to do the maths by hand? — the Work Calculator does it instantly, for free, with the formula and a worked example built in.

Frequently asked questions

The formula is: Work done = Force × Distance. With force of 100 N and distance of 5 m, the work done works out to 500.000.

Gather each input, apply the formula step by step keeping your units consistent, and round only at the end. You can verify your answer instantly with the Work Calculator.

It uses the standard formula with exact arithmetic, so the result is correct for the inputs you enter. Bear in mind that real-world outcomes can still differ when underlying assumptions change.
