Steering Ratio Calculator

Formula

The formula to calculate the Steering Ratio is:

\[ SR = \frac{SW}{W} \]

Where:

\(SR\) is the Steering Ratio (steering:wheel)
\(SW\) is the degrees of turn of the steering wheel
\(W\) is the degrees of turn of the road wheel

What is Steering Ratio?

The steering ratio refers to the relationship between the degrees of turn of the steering wheel and the degrees of turn of the road wheels. It is an important factor in determining how responsive a vehicle's steering system is. A lower steering ratio means more responsive steering, while a higher steering ratio means less responsive steering.

Example Calculation 1

Let's assume the following values:

Degrees of Turn of the Steering Wheel (SW) = 540
Degrees of Turn of the Road Wheel (W) = 30

Using the formula:

\[ SR = \frac{540}{30} = 18 \]

The Steering Ratio is 18:1.

Example Calculation 2

Let's assume the following values:

Degrees of Turn of the Steering Wheel (SW) = 360
Degrees of Turn of the Road Wheel (W) = 20

Using the formula:

\[ SR = \frac{360}{20} = 18 \]

The Steering Ratio is 18:1.
