Calculate Scale of a Model

Calculator for the scale and the sizes of a three-dimensional model. Length, width and height change according to the scale. The surface area changes with the scale squared, the volume changes with the scale to the power of three.
Please enter a scale, the original or model sizes and select the units. Each other value will be calculated.

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.
