The measurement in centimetres.
Centimetres are the unit a metric tape is read in at arm's length, so this is usually something measured on site — an opening width, a worktop height, the depth an appliance has to fit into. Drawings are a different matter: metric construction drawings are dimensioned in millimetres, so a figure taken off a drawing is ten times this one.
Length
39.37 in
1 inch = 2.54 cm exactly, so one centimetre is 1 / 2.54 ≈ 0.3937 in. Exact by definition — the uncertainty is in the tape reading, not in the factor.

Centimetres are the unit people measure in when they are holding the tape themselves, and inches are the unit the product is sold in across North America. The gap between them is where appliance openings, furniture runs and clearance checks go wrong: a dishwasher space measured at 60 cm is 23.6 in, and the US machine that fits it is sold as a 24 in unit, which is 61 cm. A converted number tells you whether something fits; it does not tell you whether the two things were ever designed to the same module, and for cabinetry, appliances and sheet goods they were not. Convert freely to compare, then buy against the size the product is actually listed at.
