Convert everything to inches (1 foot = 12 inches); then multiply the number of inches by 2.54 to convert to centimeters.
5mm = 1/2 cm
5 feet 2 inches = 157.48 cm
5' 2" = 157.5 cm
2*(5 + 20) cm = 2*25 cm = 50 cm.
1 cm = 0.3937 in. 158 cm = 62.2 in. = 5' 2"
5' 2" = 157.5 cm
5 centimeters is 50 millimeters
The idea is to: 1) Convert everything to the same unit. For instance, convert the meter to the equivalent in cm. 2) Divide the meter (or its equivalent in cm) by 5 cm.
10*2+5*2 = 30 CM
5 cm
5 cm = 50 millimeters
No 5' 2" = 157.48 cm 165 cm = 64.96" = almost exactly 5' 5"
