Weight of Aluminum Rounds

The Weight of Aluminum Rounds calculator computes the average weight of aluminum round bars based on the number and dimensions of the bar, and an average density of 2700 kg/m³ for aluminum bars.

INSTRUCTIONS: Enter the following:

• (n) Number of bars
• (L) Length of the bars
• (D) Diameter of the bars
• (ρ) Density of metal

Weight of Aluminum Round (M): The function returns the weight in pounds. However this can be automatically converted to compatible units via the pull-down menu. 

The Math / Science

Aluminum is widely used for fabrication projects where lightweight and corrosion resistance is a concern. It is generally regarded as an excellent material for welding, good for machining or grinding, and poor for bending or forming.

The formula for the weight of metal bars is as follows:

         M = ρ • n • π • (D/2)² • L

where:

• M is the mass or weight of metal bars
• ρ is the density of the metal
• n is the number of bars
• D is the diameter of the bars
• L is the length of the bars
