Quite often I come across a plan that is using meters and centimeters as the means of calulation. Being an ignorant American whose school system refused to follow the world's lead of the metric system, I have borrowed a formula for a quick and easy conversion.
The Formula
cm (centimeters) divided by 2.54 = in (inches)
For Example:
35.433 inches/ 12 inches (foot) = 2.9527
To convert the centimeters directly to feet let's take 2.54 x 12 = 30.48
