Filament Density Calculator

Determine the density of an unknown filament by measuring a known length and weight.

How It Works

Cut a known length of filament, weigh it precisely, and enter the diameter. The calculator divides weight by volume to find density, helping identify unknown materials.

Formula

Density (g/cm3) = Weight (g) / (PI x (diameter/2)^2 x length (cm))

Frequently Asked Questions

Why does density matter?

Density determines how much a given length of filament weighs. Accurate density is needed to convert between grams and meters for cost and usage calculations.

How accurate is this method?

With a digital scale accurate to 0.01g and a 50cm sample, you can determine density to within 2-3%, sufficient for most calculations.
