Brass Weight Calculator
This brass weight calculator finds the weight of a brass part from its shape and dimensions. Enter the size and the brass weight calculator returns the weight, using the density of brass. As a brass material weight calculator it handles bar, rod, and sheet, so you can weigh a brass section before you buy or ship it.

What the brass weight calculator shows
Brass is denser than steel, so a brass part weighs more than a steel one of the same size, and the brass weight calculator captures that. It finds the volume from the dimensions you enter, then multiplies by the density of brass, about 8.5 grams per cubic centimeter. As a brass material weight calculator it works for a bar, a rod, or a sheet, returning the weight in kilograms.
How the brass material weight calculator finds weight
The brass material weight calculator multiplies the volume by the density of brass:
The volume comes from the shape: a flat bar is length times width times thickness, and a round rod is the circle area times the length. Brass sits near 8.5 grams per cubic centimeter, denser than steel at 7.85, which is why the same size weighs more in brass. The brass weight calculator applies the right volume for the shape you choose.
Brass weight calculator example
A brass flat bar 1000 mm long, 100 mm wide, and 10 mm thick. The brass weight calculator gives:
So the brass bar weighs about 8.5 kg. A 50 mm brass round bar 1 m long comes out near 16.7 kg. Change the size and the brass weight calculator updates the weight at once.
How to use the brass weight calculator
Enter the dimensions of the brass part in millimeters, the length with the width or diameter and the thickness or wall, then the brass weight calculator returns the weight. Pick the shape that matches your section. For a flat bar enter length, width, and thickness; for a rod enter the length and diameter. The brass material weight calculator does the volume and density for you.
Reading the brass weight calculator result
The weight in kilograms is what a supplier prices and a courier charges by, so it is the number to order and ship against. Because brass is dense, small parts add up quickly, and a brass fitting weighs noticeably more than a steel or aluminum one of the same size. The exact figure shifts a little with the brass alloy, since different brasses have slightly different densities, but 8.5 is a sound working value. The brass weight calculator gives the nominal weight for the shape you enter.
When to use the brass bar weight calculator
- Pricing stock by weight with the brass bar weight calculator
- Estimating shipping for a brass part
- Weighing sheet with a brass sheet weight calculator
- Comparing brass with steel or aluminum by weight
Common brass weight calculator mistakes
- Using steel density. Brass is denser than steel, so a steel figure underestimates a brass part.
- Forgetting the bore. A brass pipe or tube is hollow, so subtract the bore rather than treating it as solid.
- Wrong shape. Match the shape to your section, since a rod and a sheet of the same metal weigh differently.
Tips for brass takeoffs
- Use about 8.5 g/cm³ for brass, higher than steel.
- Subtract the bore for pipe and tube sections.
- Order and ship by the calculated weight, not the size.
Brass rod weight calculator and brass sheet weight calculator
The shape decides the volume, and the volume decides the weight, which is why a brass rod weight calculator and a brass sheet weight calculator give different answers for the same amount of metal spread differently. A round rod uses the circle area, pi over four times the diameter squared, times the length, so a 50 mm brass rod one meter long holds about 1963 cubic centimeters and weighs near 16.7 kg. A brass sheet uses length times width times thickness, so a thin, wide sheet can weigh the same as a compact bar. A brass plate weight calculator is the same as the sheet case with a greater thickness. In every shape the density stays at about 8.5, so once you have the volume, the weight follows directly.
Brass round bar weight calculator by shape
Brass comes in many profiles, and a brass round bar weight calculator, a brass square bar weight calculator, and a brass pipe weight calculator each handle a different cross section. Solid sections, round or square, use the full area, while a pipe or tube subtracts the hollow bore, so a brass pipe weighs far less than a solid rod of the same outside size. Hex bar, common for fittings and fasteners, uses the hexagon area. Across all of them the metal is the same, so the round bar weight calculator shows the same shape math in steel, only with a lower density. Pick the shape, enter the dimensions, and the brass weight calculator applies the brass density to the right volume.
Brass weight calculator density reference
Density of brass next to other common metals, so you can see why the brass weight calculator returns a heavier result:
| Metal | Density (g/cm³) | Note |
|---|---|---|
| Brass | 8.5 | Denser than steel |
| Copper | 8.96 | Heaviest of these |
| Steel | 7.85 | Common baseline |
| Aluminum | 2.70 | About a third of brass |
Brass Weight Calculator FAQ
How does the brass weight calculator work?
It finds the volume from the shape and dimensions, then multiplies by the density of brass, about 8.5 g/cm³. The brass weight calculator returns the weight in kilograms.
What is the density of brass?
About 8.5 grams per cubic centimeter, though it varies a little by alloy. That is denser than steel, so a brass part weighs more than a steel one of the same size.
Can it weigh a brass rod or sheet?
Yes. As a brass rod weight calculator or a brass sheet weight calculator it uses the volume for that shape, then the same brass density.
Why is brass heavier than aluminum?
Brass is about three times as dense as aluminum, so the same size in brass weighs roughly three times as much. Density, not size, drives the difference.
