Scale Calculator - Ver 1.2

Quick Overview:
This page is set up to allow you to work with a regular ruler and come up with scale sizes of things. For example, if you have an HO scale (1:87.1) box car that is 6 in. long, the program will convert that measurement to its actual size (43 ft. 6-41/64 in.) Conversely, if you know that your 1967 Chevy Impala is 16 ft. 2 in. long, you can find out it would be 1-7/32 in. long in N Scale (1:160).

Example:
You have a large O Scale (1:48) train layout with a 54 foot 11-57/64 inch mainline run, and you want to know how long that is in real feet. Type in the 54 in the Scale Size (Model) section Feet box, 11 in the Inches box, and 57/64 in the Fraction box. Then choose [1:48 - O] from the Scale box. Now, click on the Convert to Actual button and you'll see 2639 ft. 11-13/16 in. appear in the Actual Size (Real World) section. This would make your O scale (1:48) mainline roughly 1/2 mile long.

Note: If it does not work, you'll need Javascript turned on in your browser for the calculator to work.
