Roll length is a calculator that enables the user to enter values in any three of the four following fields: Roll OD, Core OD, Thickness, Length and calculate the remaining fourth unknown value. The following units of measure can be selected: inches, feet, millimeters, centimeters, meters, microns, gauge, mils.
This powerful calculator goes a step further and allows the user to enter actual measured values in all four fields and create a correction factor that can be designated as Product A, B, C or D. This correction factor can be assigned to a new calculation and is useful for thin films where the surface roughness is sufficient to create an air gap between the wound in layers in a roll. The correction factor can be ignored in most situations and the user selects Universal for a factor of 1.0 for no correction.
The code has been updated to be compatible with the most recent versions of iOS.
The layouts have been changed to take advantage of the latest software features.
A new view has been added with links to other apps, books and videos created by the developer.
