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

Test your knowledge using the equation and check your answer with the calculator..

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