Scale Calculator

The Scale Calculator is a small Windows application that does real-time scale calculations from feet and inches or metres. It is a small window that sits on top of any other application you are running at the time.

Simply type in the actual size in feet and inches or metres and the calculator shows the scale size in millimeters. The Scale Calculator comes with conversion for HO, 00, 7mm and 1/48 scale. If your chosen scale is not shown, no problem. Add your own! Full instructions for use are available by clicking the help button.

The Scale Calculator also backwards converts. Type in the scale size and it converts back to feet and inches or metres, which ever is selected at the time.

The Scale Calculator is available only for Windows, and comes as a zipped up Windows installation file. It is brought to you by Hollywood Foundry.
