The measurement method for camber is as shown in the diagram below, and our standard measurement length is 1 meter.
When bending with the same curvature radius, there is the following relationship between the measurement length and camber.
R：Curvature Radius
C：Camber
L：Measurement Length
The following formula can be used to obtain the converted camber value when the measurement length is changed.
L0：Measurement Length
C0：Camber
L1：Converted measurement length
C1：Converted camber
[Example] If the camber is 3mm for every 1 meter in length, what would be the camber for a length of 2 meters?
∴The answer would be 12mm.
