Enter the length (in), the diameter (in), and the number of active coils into the Spring Pitch Calculator. The calculator will evaluate the Spring Pitch.
Spring Pitch Formula
The following formula is used to calculate the Spring Pitch.
SP = (L-3*D)/NA
Variables:
- SP is the Spring Pitch (in/coil)
- L is the length (in)
- D is the diameter (in)
- NA is the number of active coils
To calculate the spring pitch, subtract 3 times the diameter from the length, then divide by the number of active coils.
How to Calculate Spring Pitch?
The following steps outline how to calculate the Spring Pitch.
- First, determine the length (in).
- Next, determine the diameter (in).
- Next, determine the number of active coils.
- Next, gather the formula from above = SP = (L-3*D)/NA.
- Finally, calculate the Spring Pitch.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
length (in) = 5
diameter (in) = .25
number of active coils = 3
SP = (L-3*D)/NA = ?
