The centimetre (SI symbol: cm) is a unit of length in the metric system equal to 10−2 metres ( 1 100 m = 0.01 m). To help compare different orders of magnitude, this section lists lengths between 10 −2 m and 10 −1 m (1 cm and 1 dm). 1 cm – 10 millimetres. 1 cm – 0.39 inches. 1 cm – edge of a square of area 1 cm 2.

This line, designated 6/6 (or 20/20), is the ...
Also the only flag with a decimal ratio below 1 (i.e. taller than it is wide). While the red inner part has a ratio of exactly 4:3 (0.75), [66] the complete flag has an irrational aspect ratio of approximately 1.21901:1 due to the blue border. [Note 3][67] Netherlands. 2:3 (1.5) [68] Compare to the flag of Luxembourg.
