The Length of a Helix calculator computes the linear length of a spiral or helix where the helix is pulled into a straight line.
INSTRUCTIONS: Choose units and enter the following:
- (H) Height
- (P) Pitch: distance between turns
- (D) Diameter
Length of Helix (L): The calculator returns the length of the helix in meters. However this can be automatically converted to compatible units via the pull-down menu.
The Math / Science
The formula for the length of a helix is:
`L = H/P * sqrt( (pi*D)^2 + P^2)`
where:
- L = Length of Helix
- H = Height of Helix
- P = Pitch of Helix
- D = Diameter of Helix
Note: The number of turns (n) is equal to (H/P)
A HELIX 
is a three dimensional spiraling circular object. The most common application of the helix shape is in the common spring. A helix has a height or length, diameter and pitch, where pitch is the measurement between the spirals (see diagram).
Helix Calculators:
- Length of Helix - Computes the length of the material composing the helix if elongated.
- Height of Helix - Computes the height of a helix based on length of material, pitch and diameter.
- Volume of Helix - Computes the total displacement of helix cylinder and the displacement of the helix material as if in liquid.
