Filament Weight Calculator
Convert filament length in meters to weight in grams for any filament diameter and material.
How It Works
Enter the filament length, diameter (1.75mm or 2.85mm), and material density. The calculator computes the cylinder volume and multiplies by density to give weight in grams.
Formula
Weight (g) = PI x (diameter/2)^2 x length (cm) x density (g/cm3)
Frequently Asked Questions
What is the density of PLA?
PLA density is approximately 1.24 g/cm3. ABS is 1.04, PETG is 1.27, TPU is 1.21, Nylon is 1.13.
How do I use this?
If your slicer shows meters of filament used, enter that length here to get the weight in grams for purchasing or cost calculations.
