Film Yield Calculator
From mass, width, thickness and resin, get the metres and m² of film you can produce, and m² per kg. The reverse of the film weight calculation.

How film yield is calculated
Film mass = width × thickness × length × density, so yield just rearranges it: length = mass ÷ (width × thickness × density) and area = mass ÷ (thickness × density) (SI units — metres and kg/m³; 1 µm = 0.000001 m). Thinner film or a lighter resin yields more metres per kg. Densities are typical grade values — confirm your resin's datasheet. To go the other way (film → kg) use the film weight calculator; for line throughput use the film output calculator.
