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

## Brass Weight Formulas

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

Brass Flat Sheet Weight Formula = L * W * H * d

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

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

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

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

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

Brass 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 Brass?

The average density of Brass is 0.315 lbs/in^3.
