kilo, hecto, deca, base, deci. centi, mili, micro, nano. 5.00 decimiters. Move the decimal one place to the right because since centi is smaller than deci you will have more of it. its 50.0 centimeters
The larger spaces are usually inches. The other side will be in centimeters. In the picture above you can see the longer lines, with the numbers next to them. Those are the inches. The shorter lines represent the centimeters. There are 2.54cm to each inch. So if you have 29.5 cm it will be 11.55 inches. If you are measuring it in inches, then 29.5 inches is 74.93 cm.
