DUNMORE Announces New ‘Roll-to-Roll’ Conversion Calculator App for Smartphones

January 9, 2025
A new smartphone app from DUNMORE Corporation includes a comprehensive list of calculations and conversions useful for label converters or professionals working with continuous web substrates. The free application, available now for iPhones and Android devices, helps label converters and industry manufacturers quickly calculate roll outside diameter and roll length.

Calculating Film Thickness


The DUNMORE Roll-to-Roll calculator is foremost a roll diameter calculator. It uses film thickness, roll diameter and core size to determine the total length of the substrate. Conversely, it calculates the overall roll diameter if you use the film thickness, length and core size as inputs. However, that’s not all it can do.

“While developing the app, we considered what calculations would be valuable to label converters, film manufacturers, adhesive coaters and other professionals working with continuous web substrates,” said Michael Sullivan, Marketing Communications. “We’re not reinventing the wheel here - these calculations are available online and widely used throughout the label industry - we’re simply increasing accessibility. We wanted to develop a convenient tool that could be used on the manufacturing floor or on the road to help make more informed decisions quickly.”

In addition to label converters and industry manufacturers, DUNMORE’s Roll-to-Roll Calculator is helpful to anyone who works with materials in roll form, whether fabrics, films, foils or other substrates.

The app allows users to quickly:

  • Calculate roll outside diameter
  • Calculate roll length from diameter
  • Determine the resistance of a metalized substrate
  • Calculate yield from length
  • Calculate total material needed from label parameter
  • Calculate yield using specific gravity
  • Quick conversions for area, weight, distance and thickness

The DUNMORE Roll-to-Roll conversion calculator is available as a FREE DOWNLOAD:
