    Worked example

    Calculated with the default values shown in the form.

      Technical notes

      • Trade conversions are volume-equivalent: a 18 mm sheet equals 4.5 sheets of 4 mm.
      • The base thickness (4 mm, 6 mm, 19 mm…) differs between plants, buyers and contracts. Confirm it before reporting figures.
