Choose one direction
Real to model divides by N; model to real multiplies by N. Units are converted explicitly.
A small model, with the numbers right
Convert a whole dimension list at one 1:N scale. Move from real measurements to a model, or measure a model and work back to the real size — without mixing the units.
Real to model divides by N; model to real multiplies by N. Units are converted explicitly.
Label up to 50 dimensions. Every row shares the scale, direction and units you set.
Exact fractions power the calculation; displayed values round to six decimal places when needed.
