How to Calculate the weight of MS Angle? Simple way to calculate Mild Steel weight

What is MS Angle?

MS angle, or mild steel angle, is a type of steel angle that is made from low carbon steel. It is a versatile and widely used construction material, and it is known for its strength, durability, and corrosion resistance.

How to Calculate the weight of MS Angle?

To calculate the weight of a mild steel angle (MS angle), you will need to know the size and thickness of the angle, as well as the density of the steel. Here is the formula for calculating the weight of an MS angle:

Weight (kg) = (Length (m) x Width (m) x Thickness (m) x Density (kg/m3))

For example, if you have an MS angle that is 2 meters long, 0.5 meters wide, and 0.1 meters thick, and the density of the steel is 7,850 kg/m3, the weight of the angle would be:

Weight (kg) = (2 m x 0.5 m x 0.1 m x 7,850 kg/m3) = 0.78 kg

It’s important to note that this formula assumes that the angle is in the shape of a rectangular bar. If the angle has a different shape, such as an L-shaped or T-shaped angle, the weight may be calculated differently.

It’s also worth noting that the density of steel can vary depending on the type of steel and the manufacturing process used. In general, the density of mild steel is around 7,850 kg/m3, but it can range from 7,600 to 8,000 kg/m3. If you are unsure of the density of the steel you are using, you can check with the manufacturer or refer to a materials reference guide.

Type of Angle : There are Two Type of Angle

Updated November 2026. Quick answer: for an equal MS angle, weight per metre ≈ (2A − t) × t × 0.00785, where A is the leg length and t the thickness, both in mm. A 50 × 50 × 5 mm angle works out to about 3.73 kg/m.

1# Equal Angle

2# Unequal Angle

Example of Equal Angle:

25x25x2.5mm

30x30x2.5mm

38x38x4mm

50x50x5mm

60x60x5mm

75x75x6mm

100x100x6mm

Example of Unequal Angle:

50x25x6mm

100x75x6mm

120x60x6mm

150x75x10mm

For Example Ms For example M.S. Angle 50x50x5mmx6mtr

50×0.091×5=22.75kg

IF you need 1mter weight then Just Divide By 6.

22.75/6=3.792kg

Worked examples

• 40 × 40 × 4 mm: (80 − 4) × 4 × 0.00785 = 2.39 kg/m
• 50 × 50 × 5 mm: (100 − 5) × 5 × 0.00785 = 3.73 kg/m, or 22.4 kg per 6 m
• 75 × 75 × 6 mm: (150 − 6) × 6 × 0.00785 = 6.78 kg/m

Published tables give slightly higher figures (for example 3.77 kg/m for 50 × 50 × 5) because rolled angles have a rounded root corner that adds a little steel. The formula is accurate within about 1 to 2%.

Unequal angles

For an unequal angle A × B × t, use (A + B − t) × t × 0.00785. For example, 75 × 50 × 6 mm: (75 + 50 − 6) × 6 × 0.00785 = 5.60 kg/m.
