Gear Ratio & Torque Calculator vs Torque and Power Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
Gear Ratio & Torque Calculator
Compute the output torque, gear ratio, and mechanical advantage of a gear pair given tooth counts, input torque, and efficiency. Use this when designing gearboxes, drivetrains, or any power transmission system.
- Answers
- Output Torque (Nm)
- Inputs
- Input Gear Teeth, Output Gear Teeth, Input Torque, Gear Efficiency
Torque and Power Calculator
Convert between torque, rotational speed, and mechanical power for motors, engines, and drivetrain components. Use it when sizing a motor or verifying shaft power output at a given RPM and efficiency.
- Answers
- Result (kW)
- Inputs
- Torque, Rotational Speed, Mechanical Efficiency, Calculate
