Standard metric foot sizes can be converted to the nearest Paris point (2 ⁄ 3 cm) sizes using approximate conversion tables; shoes are marked with both foot length in millimetres, as for pointe ballet shoe sizes, and last length in European Paris point sizes (although such converted Stichmaß sizes may come 1 ⁄ 2 to 1 size smaller than ...
Oil and petrol is sold in litres. Vehicle tyres (as in the rest of the world) mark the rim diameter in inches and the width in millimetres, such that a tyre marked '165/70R13' has a width of 165 mm, an aspect ratio (profile) of 70% and a 13-inch rim diameter. Tyre pressures may be given in either kilopascals (kPa) or pounds per square inch (PSI).
