Gear ratio from tooth counts calculator

Quick Answer

The gear ratio from tooth counts calculator computes gear ratio from the input values you provide.

Result Interpretation

The result shows Gear ratio in ratio, computed directly from the entered inputs using the formula defined for this tool.

Worked Example

Verified calculation

Given:

teeth_driver = 20
teeth_driven = 40

Expected Result:

gear_ratio = 2

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from automatically validated test cases.

Formula / Method

gear ratio = driven gear teeth / driver gear teeth

Gear ratio.
