Enter the rise of the helix in one revolution and the circumference of the helix into the Helix Length Calculator. The calculator will evaluate the Helix Length.

## Helix Length Formula

The following two example problems outline the steps and information needed to calculate the Helix Length.

HXL = SQRT ( R^2 + C^2)
• Where HXL is the Helix Length
• R is the rise of the helix in one revolution
• C is the circumference of the helix

To calculate the helix length, sum the rise squared and circumference squared, then take the square root of the result.

## How to Calculate Helix Length?

The following example problems outline how to calculate Helix Length.

Example Problem #1:

1. First, determine the rise of the helix in one revolution.
• The rise of the helix in one revolution is given as: 4.
2. Next, determine the circumference of the helix.
• The circumference of the helix is provided as: 5.
3. Finally, calculate the Helix Length using the equation above:

HXL = SQRT ( R^2 + C^2)

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

HXL = SQRT ( 4^2 + 5^2) = 6.403

Example Problem #2:

For this problem, the variables required are provided below:

rise of the helix in one revolution = 8

circumference of the helix = 9
