Understanding the relationship between gear ratios and torque is crucial in mechanical engineering and automotive applications. The Gear Ratio To Torque Calculator helps determine the output torque based on a given input torque and gear ratio. This calculation is essential for designing and analyzing mechanical systems involving gears.

## Formula

The formula to calculate the output torque (ToutT_{out}Tout) is:

*T*<*sub*>*out*</*sub*>=*T*<*sub*>*in*</*sub*>∗*R*

where:

- ToutT_{out}Tout is the output torque (Nm)
- TinT_{in}Tin is the input torque (Nm)
- RRR is the gear ratio

## How to Use

To use the Gear Ratio To Torque Calculator:

- Enter the input torque in Newton meters (Nm).
- Enter the gear ratio.
- Click the “Calculate” button.
- The output torque will be displayed in Newton meters (Nm).

## Example

Suppose you have an input torque of 150 Nm and a gear ratio of 3.5. Using the calculator:

- Enter 150 in the input torque field.
- Enter 3.5 in the gear ratio field.
- Click “Calculate.”
- The output torque is calculated as 525 Nm.

## FAQs

**What is gear ratio?**- Gear ratio is the ratio between the number of rotations of the input gear to the output gear.

**Why is torque important in gear systems?**- Torque determines the rotational force available to perform work, which is crucial in mechanical systems.

**Can the calculator be used for any gear system?**- Yes, the calculator can be used for any system where gear ratios and torque need to be calculated.
