1:72 Scale to 28mm Conversion

This conversion is how you check a specific vehicle before buying it for that purpose.
To convert a model dimension from 1:72 Scale to 28mm (1:56), multiply it by 1.2857 (72 ÷ 56). The result is a larger model — every length, width, and height changes by the same factor.
