Gear Ratio Calculator – Formula, Free Online Tools, Mobile Apps & FAQs for South Africans
What Is a Gear Ratio Calculator?
A gear ratio calculator is a tool used to determine the ratio of the number of teeth between two interlocking gears. In South Africa, this calculator is beneficial for mechanics working on vehicles, cyclists, and even hobbyists building machinery. Understanding gear ratios helps with optimizing performance, fuel efficiency, and power transfer.
How to Calculate Gear Ratio Manually
The formula to calculate gear ratio is:
Gear Ratio = (Number of Teeth on Driven Gear) / (Number of Teeth on Driving Gear)
For example, if the driven gear has 20 teeth and the driving gear has 40 teeth, the gear ratio would be 20/40 = 0.5.
Let’s say you have a bicycle with a front gear (driving gear) that has 40 teeth and a back gear (driven gear) with 20 teeth. The gear ratio would be 20/40 = 0.5 or 1:2, meaning the back wheel rotates half as fast as the front gear.
