Enter the inches of travel (in) and the number of rotations into the Twist Rate Calculator. The calculator will evaluate the Twist Rate.

## Twist Rate Formula

The following two example problems outline the steps and information needed to calculate the Twist Rate.

TW  = D / R
• Where TW is the Twist Rate (inches/rotation)
• D is the inches of travel (in)
• R is the number of rotations

To calculate the twist rate, divide the inches of travel by the number of rotations.

## How to Calculate Twist Rate?

The following example problems outline how to calculate Twist Rate.

Example Problem #1:

1. First, determine the inches of travel (in).
• The inches of travel (in) is given as: 30.
2. Next, determine the number of rotations.
• The number of rotations is provided as: 3.
3. Finally, calculate the Twist Rate using the equation above:

TW  = D / R

The values provided above are inserted into the equation below and computed.

TW  = 30 / 3 = 10 (inches/rotation)

Example Problem #2:

For this problem, the variables required are provided below:

inches of travel (in) = 60

number of rotations = 4
