Angle Weight Calculator
This angle weight calculator finds the weight of an L shaped steel angle from its leg sizes, thickness, and length. Enter them and the angle weight calculator returns the total weight and the weight per meter. As an ms angle weight calculation tool it uses the standard steel density, so it matches mill tables for equal and unequal angles.

What the angle weight calculator shows
A steel angle is an L shaped bar, and the angle weight calculator finds its weight from the size of the two legs, the thickness, and the length. It works out the L cross section, multiplies by the length for the volume, and multiplies by the steel density for the weight. As an l angle weight calculator it handles both equal legs, like a 50 by 50, and unequal legs, and returns the weight per meter and the total.
The ms angle weight calculation formula
The ms angle weight calculation finds the L cross section, then multiplies by length and steel density:
The area formula counts the two legs without double counting the corner. Steel density is about 7,850 kg per cubic meter, so the angle bar weight calculation lands on the nominal figure. Divide the total by the length for the weight per meter.
L angle weight calculator example
A 50 by 50 by 6 mm equal angle, 1 m long. The l angle weight calculator gives:
So a 50 by 50 by 6 angle weighs about 4.43 kg per meter. Change the legs or thickness and the angle weight calculator updates the weight at once.
How to use the angle weight calculator
Enter the two leg sizes and the thickness in millimeters and the length in millimeters, then the angle weight calculator returns the total weight and the weight per meter. Use the nominal leg and thickness stamped on the section, such as 50 by 50 by 6. For a schedule, run each angle steel weight calculator size once and add the totals.
Reading the angle weight calculator result
The weight per meter is the unit weight for that section; the total is that value times the length and quantity. Order steel by total weight, since mills and yards price by the kilogram or ton. A thicker leg or a longer leg both raise the section area and so the weight, in near proportion. For stainless, the density is a little higher than mild steel, so an ss angle weight calculation runs slightly heavier for the same size.
When to use the angle steel weight calculator
- Pricing an order by weight with the angle steel weight calculator
- Building a bar schedule with the angle weight calculator
- Checking a delivery with an angle iron weight calculator
- Comparing equal and unequal sections
Common angle weight calculator mistakes
- Double counting the corner. The area formula subtracts the thickness once, so do not add both legs in full.
- Wrong material density. Steel, stainless, and aluminum differ, so set the right one for the angle.
- Using outside leg for area. Use the nominal leg and thickness stamped on the section.
Tips for angle takeoffs
- Run each angle size once and add the totals for a schedule.
- Order by weight, since steel is priced by the kilogram or ton.
- Switch the density for stainless or aluminum sections.
MS angle weight calculation and angle bar weight calculation
The ms angle weight calculation rests on one neat idea: an L section is just two rectangles that share a corner, so its area is leg A plus leg B minus the thickness, all times the thickness. Subtracting the thickness once removes the corner that the two legs would otherwise count twice. Multiply that area by the length for the volume and by the steel density for the mass, and the angle bar weight calculation is done. Mild steel sits at about 7,850 kg per cubic meter, which is where the mill table figures come from, so an ms angle weight calculator in kg simply applies this density to the section you enter. Because weight scales with the section area, a small rise in thickness adds weight across the whole length, which is why heavier duty angles of the same leg size cost noticeably more steel.
Equal angle weight calculator for steel and aluminum
Material is the other lever. An equal angle weight calculator for mild steel uses 7,850 kg per cubic meter, while a stainless steel angle weight calculator runs a little heavier near 8,000, so an ss angle weight calculation adds a few percent for the same size. An aluminium angle weight calculator, or aluminum angle weight calculator, tells a different story: aluminum is about a third the density of steel, near 2,700, so the same 50 by 50 by 6 angle weighs roughly a third as much. That weight saving is why aluminum angles suit frames, trailers, and anything that moves, even though they carry less load than steel of the same size. Set the material density to match, and the section formula stays the same.

Angle Weight Calculator FAQ
How does the angle weight calculator work?
It finds the L cross section from the legs and thickness, multiplies by length and steel density. The angle weight calculator returns the weight per meter and the total.
What does a 50 by 50 by 6 angle weigh?
About 4.43 kg per meter for mild steel. The 50 * 50 * 6 angle weight per meter comes from a 564 mm² section times the steel density.
Does grade change the weight?
Only a little. Mild and structural steel share about the same density, so an ms angle weight calculation and a structural one match; stainless runs slightly heavier.
Can it handle unequal angles?
Yes. Enter different leg sizes and the l angle weight calculator uses the same area formula, so unequal angles work as well as equal ones.
