If someone asked me how tall I was? (How tall are you?) I'd answer "five-nine" which would be the idiomatic way of saying 5 feet, 9 inches tall. In the metric system, 5-9 would be just over 175 cm. The measure you asked about 5-4 would be about 163 cm. Hope this helps!

To describe your height to someone. This is the Imperial system used by the USA, and in casual conversation in many parts of the world. I know my height in Metric because that is what is printed on my drivers license, but I tend to think of height in feet and inches. Metric would be 162 cm. So if you are 162 cm tall you would say "I am five four or 5 foot 4" if you wanted to say your height in feet and inches. If people want to know they will ask "how much in feet?" or "how much is that in feet?"

I know that this is an old question, but if you haven't figured it out already, here is how you convert SI to the imperial system: 1 foot = 12 inches 1 inch = 2.54 cm 5' 4'' = 5 feet and 4 inches = 5*12+4 = 64 inches 64 inches = 64*2.54 = 64*(2.5+0.04) = 640/4 + 0.64*4 = 160 + 2.56 ~ 162.5 cm

It's your height
