For us used to the metric system, here is a small conversion table for some of the more common units encountered in this forum:

Inches:
1" = 2.54 cm
2" = 5.08 cm
4" = 10.16 cm
6" = 15.24 cm
24" = 60.95 cm
32" = 81.28 cm
42" = 106.68 cm
48" = 121.91 cm
Actually the designation of one apostrophe/single quote (') designates "foot" (i.e. 12 inches). For inches, you want the double apostrophe/double quotes ("). So, I have made the correction above.

Here, I'll reverse it for the benefit of those used to the Imperial system for translating from metric:

100 mm = 10 cm = 3.94" = approx. 1/3 foot
200 mm = 20 cm = 7.97" = approx. 2/3 foot
300 mm = 30 cm = 11.81" = approx. 1'
400 mm = 40 cm = 15.75" = approx. 1' 3 3/4"
500 mm = 50 cm = 19.685" = approx. 1' 7 2/3"
