Use this gear ratio calculator to quickly find the gear ratio between two gears based on their teeth count.

## Gear Ratio Calculator Explanation

This gear ratio calculator allows you to calculate the secondary gear speed based on the primary gear speed and the number of teeth in the primary and secondary gears.

### How to Use the Calculator:

- Enter the primary speed in revolutions per minute (RPM).
- Enter the number of teeth of the primary gear.
- Enter the number of teeth of the secondary gear.
- Click the “Calculate” button to see the result.

### How the Calculation is Done:

The formula used by this calculator is:

**Gear Ratio = Primary Gear Teeth / Secondary Gear Teeth****Secondary Speed = Primary Speed / Gear Ratio**

### Limitations:

Please ensure all input fields contain valid numerical values, and that the primary gear teeth is not zero, as this would lead to a division by zero error. The result is given to two decimal places for precision.
