Units: mm = millimeters, cm = centimeters, m = meters, in = inches, ft = feet, yd = yards

Example: a model has the scale one to thirty. Then the surcafe area scale is one to nine hundred, the volume scale is one to twenty-seven thousand. A length of six meters at the original has a length of twenty centimeters at the model.
