Ever wondered how many feet is your foot? According to the French system, the shoe size is measured as follows: shoe size = 3/2 * (length of foot in cm + 2cm). My shoe size is 42. Thus, the length of my foot in cm is (42 * 2/3) - 2 = 26cm ~ 1/4 meter. In feet, it's 26/30.5 = 0.85 feet.

This pops another questions... Who has the perfect feet? Someone with a shoe size of 3/2 * (25 + 2) = 40.5 (1/4 meter). If you are one of them; go celebrate! You 'naturally' fit into the 'French System'. Doh...
