Formula and worked answer
Formula
in = cm × 0.3937008
Substituting 100 for cm: 100 × 0.3937008 = 39.3701 in. The factor 0.3937008 comes from the exact international definition of the Centimeter relative to the Inch, so this answer is precise rather than rounded.
What does 100 Centimeters represent?
100 centimetres (39.37 in) is exactly one metre and the round-number reference figure for the length of European-spec cribs, baby cots, and toddler beds. Converted to imperial the figure is 39.37 inches, which sits just over the US "39-inch" or "40-inch" standards American baby-furniture makers publish. The 0.37-inch gap (about 9 mm) matters in cot-mattress retail: a 100 cm European mattress fits a 100 cm European cot frame with the 25-30 mm gap regulators allow, but slipping a 39-inch US-spec mattress into a 100 cm European frame leaves a 9 mm shortfall that pushes the gap above the EN 716 safety threshold.
