Figure Scale Calculator

Scale Calculator v0.04 (c) 2011

This calculates the scale size of a part/figure given its real-world size (or its size in a different scale). To use:
To determine the real-world size of a scale part, simply enter the scale size and scale in the "Original size" and "Original scale" boxes, then use an "Output scale" of 1:1

The drop-down boxes list some of the most common scale terms. Selecting one will populate the corresponding scale box with the appropriate scale value.
Some common scales (e.g. 15 mm) are treated in a manner that doesn't quite correspond to their actual scale value - 15 mm is actually 1:122, but is commonly treated as 1:100. To account for this, both the actual and scale sizes are supplied. Note that these drop-downs only put a value into the scale box. This value can be edited and changed if required, and values not in the drop-down can still be entered.
