Spur Gear Generator is unitless: you may choose inches, cm or millimeters when importing your DXF file as you will have the same value for D/P as it is set above or as imported (SI or imperial nits). Gears in SVG are measured in pixels, which is the value multiplied with the scale (Pixel per Unit) as it is displayed on the right side.

"Module" is the unit of size that indicates how big or small a gear is. It is the ratio of the reference diameter of the gear divided by the number of teeth.

Thus:

m = d / z

Module = Reference Diameter * Number of teeth

NUmber of teeth:

z = d / m

Number of teeth = Reference Number / Module

Reference pitch :

p = π * Module

Reference Pitch = Circumference / Number of teeth = ( π d ) / z
