Copper Bar Weight Calculator
Calculate weight (kg) and cost for copper busbars, flat bars, round rods and tubes — unit conversions and batch calculations included.
Input Parameters
Enter cross-section width (per piece)
Enter thickness (height) of the bar
Enter diameter per piece
If tube, you can specify OD and ID instead of wall thickness.
Length units — convert automatically
Density in kg/m³. Default pure copper = 8960 kg/m³.

Frequently Asked Questions
How do you calculate weight for a rectangular busbar?
Convert width, thickness and length to meters, compute volume = width × thickness × length (m³) and multiply by density (kg/m³) to get weight in kg.
Why do I need to choose units carefully?
Different tools mix mm/inches which causes errors. This calculator converts all inputs to meters internally to ensure consistency.
Can I use a custom density?
Yes — choose 'Custom' in the density preset and enter density in kg/m³ (for example, 8960 for pure copper).
Is cost calculation accurate?
Cost is a simple product of total weight and price per kg. For final procurement, add processing, cut loss and supplier margins.
What shapes are supported?
Rectangular flat bars, round bars and hollow/tube profiles. For complex extrusions use section area from manufacturer and input the area as width×thickness equivalent.
