Enter the filament mass (g), the density (g/cm^3), and the cross-sectional area (cm^2) into the Filament Length Calculator. The calculator will evaluate the Filament Length.
Filament Length Formula
The following formula is used to calculate the Filament Length.
FL = M / D / A
- Where FL is the Filament Length (cm)
- M is the filament mass (g)
- D is the density (g/cm^3)
- A is the cross-sectional area (cm^2)
How to Calculate Filament Length?
The following two example problems outline the steps and information needed to calculate the Filament Length.
Example Problem #1
- First, determine the filament mass (g).
- The filament mass (g) is calculated to be : 40.
- Next, determine the density (g/cm^3).
- The density (g/cm^3) is measured to be: 20.
- Next, determine the cross-sectional area (cm^2).
- The cross-sectional area (cm^2) is found to be: 2.
- Finally, calculate the Filament Length using the formula above:
FL = M / D / A
The values provided above are inserted into the equation below and computed.
FL = 40 / 20 / 2 = 1 (cm)
Example Problem #2
The variables required for this problem are provided below:
filament mass (g) = 50
density (g/cm^3) = 30
cross-sectional area (cm^2) = 5
Test your knowledge using the equation and check your answer with the calculator.
FL = M / D / A = (cm)
