⚙️ Ever wondered how to figure out the gear ratio of a system when you already know the RPMs of both gears? That’s where an RPM to Gear Ratio Calculator comes in handy!
Whether you’re into automotive tuning, bike mechanics, robotics, or engineering projects, this simple tool helps you calculate how fast or slow gears are turning relative to each other
Let’s break it down together!

To use the RPM to gear ratio calculator, enter:
- Input RPM (from motor or power source)
- Output RPM (measured or observed)
… and the calculator will tell you the gear ratio instantly

🙋 What Is a Gear Ratio?
A gear ratio tells you how many times the driving gear turns compared to the driven gear. It’s used to control speed and torque in gear systems.
The basic idea:
- Higher ratio = more torque, less speed
- Lower ratio = more speed, less torque
🙋♀️ What Is RPM?
RPM stands for Revolutions Per Minute. It’s how many full turns a gear or shaft makes in one minute.
Knowing the input and output RPMs allows you to work backward and find the gear ratio. This is especially helpful if you’re analyzing an existing gear system!
🧮 Formula: RPM to Gear Ratio
Here’s the simple formula to calculate gear ratio:
Gear Ratio = Input RPM ÷ Output RPM✅ Example
Let’s say:
- Input RPM = 1200
- Output RPM = 400
Plug into the formula
Gear Ratio = 1200 ÷ 400 = 3🎉 That means your gear system has a 3:1 gear ratio — the input gear spins 3 times for every 1 spin of the output gear.
📌 Why It’s Helpful
Knowing the gear ratio from RPM is useful when:
- You want to analyze or reverse-engineer a system
- You need to check if gears are delivering the right speed or torque
- You don’t know the gear tooth count, but you can measure RPMs
