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
There are: 550 cm in 5 and a 1/2 meters
5 feet 2 inches = 157.48 cm
5' 2" = 157.5 cm
Since 1 inch actually equals 2.54 cm (not 2.5 cm), 5 feet & 2 inches (62inches) equal 157.48 cm.
2*(5 + 20) cm = 2*25 cm = 50 cm.
Depends on what type of eraser you have. I measured the original pink eraser 5cm long.
1 cm = 0.3937 in. 158 cm = 62.2 in. = 5' 2"
5 centimeters is 50 millimeters
5' 2" = 157.5 cm
5mm = 1/2 cm
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.
