🧭 How to Use
FAQ
Q1. What is a gear ratio?
A. It is the ratio of input gear teeth to output gear teeth, determining speed and torque conversion.
Q2. Does a higher gear ratio increase torque?
A. Yes — higher ratios reduce speed but increase torque.
Q3. Can I use this for robotics and automation?
A. Absolutely — gear ratios are essential for robotic actuators and servo mechanisms.
Q4. What units should I enter?
A. Speed in RPM, torque in Nm, gear ratio as a numeric ratio (e.g., 3 = 3:1).
