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-2T)^2] * L * d
Brass Round Hollow Tube Weight Formula = pi * (R^2-r^2) * L * d
Brass Square Angle Weight Formula = (2*W*T - T^2) * L * d
Brass T bar Weight Formula = (W*T + (H-T)*T)* L * d
Brass C Channel Weight Formula = (2*W*T1+Hi*T2)* L * d
Variables used in these equations:
- L is the length
- W is the width
- H is the height
- Hi is the inner height (for the C Channel input)
- 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 lb/ft^3 so the resulting weight is in lb.
What is the density of Brass?
A typical density for brass is about 0.308 lbs/in^3 (it varies by alloy, commonly around 0.304 to 0.315 lbs/in^3).
