The figures on the tape measure are divided into two rows, one row of digital units is centimetres / CM, a row of units is inches, 1 CM about = 0.3937 inches, 1 inch about = 2.54 CM, so the two figures are shorter than the digital unit is centimetres, the longer for inches, the unit centimetres of digital font is also smaller than inches, 100 cm = 1 m, the use of general use of the unit is centimetres.
