The circular pitch on my Spur gear is roughly 3.1mm
It should be module 1
The module is the ratio of the pitch diameter to the number of teeth.
Span measurement over 4 teeth is 10.8mm
You may want to ask an engineer about this IMO, cause the pinion will have to match the spur.
If you have vernier calipers you can check this at the hobby shop against their gears.
Best bet is check it against a spur gear from your local Hobby shop and check the mesh is correct.
