Select the shape of the Carbon Fiber and enter the required variables. The calculator will evaluate and display the Carbon Fiber weight.

## Carbon Fiber Weight Formulas

The following formulas are used to calculate the weight of Carbon Fiber in different shapes.

Carbon Fiber Flat Sheet Weight Formula = L * W * H * d

Carbon Fiber Round Bar Weight Formula = pi * D^2/4 * L * d

Carbon Fiber Square Hollow Tube Weight Formula = [W^2-(W-T)^2] * L * d

Carbon Fiber Round Hollow Tube Weight Formula = pi * (R^2-r^2) * L * d

Carbon Fiber Square Angle Weight Formula = [W^2-(W-T)^2]/2 * L * d

Carbon Fiber T bar Weight Formula = (W*T – (H-T)*T)* L * d

Carbon Fiber C Channel Weight Formula = (2*W*T1+H*T2)* L * d

Variables used in these equations:

- L is the length
- W is the width
- H is the height
- d is the density
- D is the outer diameter
- T is the thickness
- R is the outer radius
- r is the inner radius
- T1 is the channel thickness along the width
- T2 is the channel thickness along the height

The units used in all calculations on the calculator are inches for lengths and lbs/in^3 for density. These can be switched for any equivalent unit as long as the density units are also changed to match. For example, if you change the lengths to feet, the density should be in lbs/ft^3 or mass/ft^3.

## What is the density of Carbon Fiber?

The average density of Carbon Fiber is 0.06683549 lbs/in^3.
