# How much does a brick weigh? Formula to Calculate

In this article, I am going to tell you “How much does a brick weigh?”. We need to calculate the weight of a single brick so that we can calculate the weight of a whole structure made of bricks. We need to calculate the weight of bricks to analyze the structure and design it according to the load due to bricks.

On the other hand, the weight of the bricks is necessary to determine the capacity of the vehicle required to transport the bricks from one place to another.

The weight of bricks depends upon several factors, like the size of bricks, the density of bricks, i.e. the quality of materials used to prepare bricks, etc. The simple formula to calculate the weight of bricks is weight = Volume x Density.

The standard size of the bricks may vary from country to country. The sizes of different types of bricks are different.

## Some of the most common sizes of solid red bricks

• Imperial size:  57 x 102 x 203 mm
• Metric size: 75 mm x 225 mm x 115 mm
• Indian size: 190 mm x 90 mm x 90 mm

## Some most common sizes of Concrete Blocks

Now, let us see some numerical examples so that we can easily understand “how much does a brick weigh”.

## How much does a brick weigh?

Let us have bricks with a length of 228 mm, a width of 114 mm, and a height of 76 mm.

Now, the Volume of one Brick = Length x Breadth x Height

V = 228 x 114 x 76

V = 0.228 x 0.114 x 0.76  (By converting all dimensions in meters)

V = 0.00197539 meter cube

Here, we have to remember that the density of bricks is 1920 Kg/m3.

So, The weight of the brick becomes = Volume x Density

i.e W = Volume x Density

i.e W = 0.00197539 x 1920 = 3.79 Kg.

Hence, The weight of one brick is 3.79 Kg. If we convert it into pounds, then it will be 8.35 pounds.

## Similarly, take an example to calculate the weight of a concrete block.

Let us have a concrete block (150 x 200 x 400) with a length of 400 mm, a width of 200 mm, and a height of 150 mm.

Now, the Volume of one Brick = Length x Breadth x Height

V = 150 x 200 x 400

V = 0.150 x 0.200 x 0.400  (By converting all dimensions in meters)

V = 0.012-meter cube

Here, we have to remember that the density of bricks ranges from 650 Kg/m3 to 2100 Kg/m3.

The heavy concrete blocks have a density of 1800–2100 Kg/m3, while the lightweight concrete blocks have a density of 650–1500 Kg/m3.

Here I am taking the density of a lightweight concrete block i.e 650 Kg/m3

So, The weight of the brick becomes = Volume x Density

i.e W = Volume x Density

i.e W = 0.012 x 650 = 7.5 Kg.

Hence, The weight of one concrete block is 7.5 Kg. If we convert it into pounds then it will be 16.5 pounds.
