How do you denote centimeters and meters?
' denotes feet
" denotes inches

Its just "m" for metres and "cm" for centimetres

You are on a computer crying about converting units? Google it!

Height in the metric system is measured in meter and centimeters, 1 meter is 3'3, and one centimeter is 0.4 inches. However, if you're lazy like me and bad at math, you can just use a converter. So 6'4; 1.93
