What this tool does
Calculate work instantly in your browser — the published formula, worked locally with no data sent anywhere. Constant force over a straight-line displacement. A force at 90° to the motion (like the normal force on a sliding box) does no work at all.
How to use the Work Calculator
- Enter or select force (n).
- Enter or select distance (m).
- Enter or select angle between force and motion (degrees).
- Read the calculated result; change any measurement to compare alternatives.
Formula
work W = F × d × cos θ — only the component of force along the direction of motion does work.
- forceN
- Force (N)
- dist
- Distance (m)
- angle
- Angle between force and motion (degrees)
Constant force over a straight-line displacement. A force at 90° to the motion (like the normal force on a sliding box) does no work at all.
Worked example
For work calculator, the following measurements illustrate the exact method: Force (N): 100; Distance (m): 5; Angle between force and motion (degrees): 0.
Inputs
- Force (N)100
- Distance (m)5
- Angle between force and motion (degrees)0
Result
- Work (J)500
- Work (ft·lbf)368.78
- Work (kcal)0.12
Results explained
- Work (J)
- Work (J) from the formula above. Constant force over a straight-line displacement. A force at 90° to the motion (like the normal force on a sliding box) does no work at all.
- Work (ft·lbf)
- Work (ft·lbf) from the formula above. Constant force over a straight-line displacement. A force at 90° to the motion (like the normal force on a sliding box) does no work at all.
- Work (kcal)
- Work (kcal) from the formula above. Constant force over a straight-line displacement. A force at 90° to the motion (like the normal force on a sliding box) does no work at all.

Every field is labelled with its unit — enter values in exactly the labelled unit and read the result in the labelled output unit. Fields with a unit symbol also support the site-wide imperial/metric switch, which converts before the formula runs.
It uses double-precision arithmetic and the published constants and formulas named on this page. The last displayed digit may be rounded, and real conditions can differ from the idealized model described in the assumptions.
