Free engineering tools
Calculators we use in our own work, published free. Each one shows every step of the calculation, so you can check it before relying on it.
The tools run entirely in your browser; inputs are not sent to us. They are provided free and without warranty, as an aid to design and checking. Results must be reviewed by a qualified engineer, who remains responsible for the design.
