Convert
Gear / Repeat Calculator
Convert between gear teeth and repeat length using a user-supplied pitch.
How it works
Gear teeth to repeat uses Repeat = Teeth × Pitch. Reverse mode divides desired repeat by pitch and reports neighboring integer options.
Example
For a 317.5 mm target and 3.175 mm pitch, the mathematical result is 100 teeth.
Limitations
Nearest integers are mathematical options only. This page does not claim that a gear exists or is purchasable.
