How to convert real dimensions to model scale
Divide the real-world measurement by the scale denominator, then convert the result into the workshop unit you prefer.
Model size = Real-world size ÷ Scale denominator
How it works
At 1:48 scale, every 48 real units become 1 model unit.
Checked example
Example: 6 feet is 72 inches. At 1:48, 72 ÷ 48 = 1.5 inches, or 38.1 mm.
Workshop notes
Keep units consistent and round only the final workshop measurement.
