For gaming figures, the formula for the ratio is 304.8 (mm per foot) multiplied by the assumed height in feet divided by the figure scale height in mm. For example, if we have a figure we assume is 6 feet to the top of the head at 54mm we have 6x304.8=1,828.8 divided by 54=33.86, rounded to 34, the ratio is 1/34. I assume 6 feet to the top of the head for size measurement and calculated the ratio accordingly. Feel free to copy the code and customize it for your particular needs.
