A steel angle is a versatile ‘L’ shaped steel structure, manufactured by bending a piece of mild steel or carbon steel. Angle weight therefore is determined by its size and thickness. Widely used in construction and engineering projects, they are fundamental in building frames and bridges, providing support, durability, strength and stability to the overall structure. As a builder, business owner, engineer, refer to an angle weight chart for precise measurements. You can also use a steel angle weight calculator for material estimation and planning.

Here, we take a look at how to calculate angle weight per meter and kg. We also understand the method of MS angle unit weight calculations and how to build a MS angle weight chart by different sizes and dimensions for quick reference.

## How to calculate angle weight?

An angle weight chart will enable you to plan for materials precisely, eliminate waste, and reduce costs in transportation and storage. Now, let us understand the steps to calculate weight of steel angles.

**Formula for angle weight calculation:**

**Weight = Length x Density x Section Area**

Here,

Density of steel = 7850 kg/m³ (standard measurement)

Length = Unit is meters (m)

So, for a 2 m long steel angle, with cross-section area of 0.0004, weight is:

**W = **2 x 7850 x 0.0004

= **6.28 kg **

### Step-by-step angle unit weight calculator

An important part of calculating the weight of an angle is to calculate the area of the cross-section area. Let’s take a look at the steps involved in angle unit weight calculation.

**Step 1:**Measure the thickness (T) and width (W) of the angle in milli meters (mm)**Step 2:**Find the Area of the cross section = A = (W-T) x T**Step 3:**Calculate the unit weight of angle per meter = Area of cross section x Density (formula for steel angle unit weight)

## What is weight of MS angle 50x50x5?

A steel angle noted as 50 x 50 x 5 means, it’s an equal angle, that is, the length of both its legs (flanges) are 50 mm each, and the thickness is 5 mm. Weight of MS angle 50x50x5 is 3.73 kg/m to 3.80 kg/m (rounded off).

L = 50 mm

T = 5 mm

#### Step 1

Since it has two legs, we will need to calculate the area of each leg and then subtract the overlapping area.

**Area of each flange/leg** = Length x Thickness = 50 mm x 5 mm = 250 mm²

**Overlap area** = Thickness x Thickness (since it’s the same) = 5 mm x 5 mm = 25 mm²

**Total area of cross section **= 2 x 250 mm² – 25 mm² = 475 mm²

#### Step 2

Convert the cross section area into square meters (m²) for use in the weight calculation formula.

= 475 mm² / (1000 x 1000) = 0.000475 m²

#### Step 3

Calculate the weight of 50x50x5 MS angle.

Formula for MS angle weight calculator:

= Length x Density x Cross-section area

= 1 m x 7850 kg/m³ x 0.000475 m²

= **3.728 kg or 3.73 kg (rounded off)**

## What is the weight of 50X50X3 mm angle?

We can use the MS angle weight calculator formula to find the weight of 50x50x3 mm angle. Using the formula for MS angle weight as Length x Density x Cross-section area, the weight of 50x50x3 mm is 2.28 kg/m or 2.3 kg/m (rounded).

Here 50x50x3 mm stands for, length of each flange/leg = 50 mm, thickness = 3 mm

Area of each leg = 50 mm x 3 mm = 150 mm²

Overlap area = 3 mm x 3 mm = 9 mm²

Total area of cross section = 2 x 150 mm² – 9 mm² = 291 mm²

Area in sq meters = 291 mm² / (1000 x 1000) = 0.000291 m²

**50x50x3 mm MS angle weight =**

= 1 m x 7850 kg/m³ x 0.000291 m²

= **2.28 kg/m or 2.3 kg/m (rounded)**

## What is the weight of 75X75X8 angle?

Let us know find the weight of 75x75x8 angle. We know the formula for angle weight calculation is: Length x Density x Area of cross-section. Using this formula we can arrive at the weight of 75x75x8 angle as 8.91 kg/m or 8.9 kg/m (rounded).

Here 75x75x8 mm stands for, length of each flange/leg = 75 mm, thickness = 8 mm

Area of each leg = 75 mm x 8 mm = 600 mm²

Overlap area = 8 mm x 8 mm = 64 mm²

Total area of cross section = 2 x 600 mm² – 64 mm² = 1136 mm²

Area in sq meters = 1136 mm² / (1000 x 1000) = 0.001136 m²

**75x75x8 mm MS angle weight =**

= 1 m x 7850 kg/m³ x 0.001136 m²

= **8.91 kg/m or 8.9 kg/m (rounded)**
