Roll Weight to Meter

Enter roll weight in KG, coil width in mm, film micron, and select the film type. The calculator deducts the core weight and gives exact length in meters.

The paper core adds weight to the roll. If you weigh a full roll without removing the core, you must deduct the core weight to get the actual film weight. Standard 3-inch cores weigh around 150–200 grams.
