Helical Spring Rate Calculator

Spring Diameter D=(m)
Wire Diameter d=(m)
Modulus of Rigidity( N / m^2) G=
Number Of Active Coils N=
Spring Rate d= (Newton/Meter2)
Spring Index (C)=

Formula:
K=(G*d)/(8*C3*N)
Where,
K = Spring Rate
d = Wire Diameter
N = Number Of Active Coils
G = Modulus of Rigidity
C =Spring Index
Thus the Helical Spring Rate calculation to calculate spring strength is made easy. Free Online Physics Calculator.
