Film & Material Calculators
Move between thickness, GSM, yield, weight and area with explicit material assumptions.
Micron to GSM
Estimate film basis weight from thickness and an editable material density. Supplier-measured GSM is preferred when available.
GSM to Micron
Estimate homogeneous film thickness from basis weight and material density in grams per cubic centimeter.
Film Yield m²/kg
Calculate the square meters of film represented by one kilogram from the actual film or laminate GSM.
kg per 1,000 m²
Express film basis weight as the kilograms needed to cover one thousand square meters.
Film Weight from Area
Convert a specified film area to net material weight using a measured or calculated GSM.
Film Area from Weight
Determine how much film area a net mass represents at a given basis weight.
Linear Meters per kg
Calculate running-meter yield for a particular web width and film GSM.
kg per Linear Meter
Calculate the net mass of each running meter of film from web width and basis weight.
Micron to Mil
Convert film thickness from micrometers to thousandths of an inch using the exact 25.4 µm per mil relationship.
Mil to Micron
Convert plastic film thickness from mil to micrometers; one mil equals exactly 25.4 µm.
Micron to Gauge
Convert micrometer thickness to plastic-film gauge where 100 gauge equals one mil.
Gauge to Micron
Convert plastic-film gauge to micrometers using 0.254 µm per gauge; metal-sheet gauge is a different system.
Film Density from GSM and Thickness
Calculate an apparent film density from measured GSM and thickness as a check on material assumptions.
Film Thickness from GSM and Density
Back-calculate the thickness of a homogeneous film using known GSM and an editable density.
Before you start
Use measured GSM when available. If you estimate GSM from thickness and density, check the resin blend and keep coatings or other layers separate from the base film.
Inputs to have ready
The exact inputs depend on the selected tool. Common inputs in this section include:
- Film thickness
- Material
- Material density
- Film GSM
- Film area
- Net film weight
