Enter the volume and density into the calculator to determine the weight of the cinder block. This calculator can also evaluate any of the variables given the others are known.

## Cinder Block Weight Formula

The following formula is used to calculate the weight of a cinder block.

W = V * D

Variables:

- W is the weight of the cinder block (lbs) V is the volume of the cinder block (cubic feet) D is the density of the cinder block (lbs/cubic foot)

To calculate the weight of a cinder block, multiply the volume of the cinder block by the density of the cinder block.

## What is a Cinder Block Weight?

A cinder block weight refers to the mass of a cinder block, also known as a concrete masonry unit (CMU). These blocks are commonly used in construction due to their strength and durability. The weight of a cinder block can vary significantly depending on its size and the materials used to make it. On average, a standard cinder block measuring 8x8x16 inches weighs approximately 28-35 pounds, although lightweight versions can weigh as little as 28 pounds while heavier, denser blocks can weigh up to 40 pounds or more.

## How to Calculate Cinder Block Weight?

The following steps outline how to calculate the Cinder Block Weight.

- First, determine the volume of the cinder block (V) in cubic feet.
- Next, determine the density of the cinder block (D) in lbs/cubic foot.
- Next, gather the formula from above: W = V * D.
- Finally, calculate the Cinder Block Weight (W) in lbs.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem:**

Use the following variables as an example problem to test your knowledge.

Volume of the cinder block (V) = 5 cubic feet

Density of the cinder block (D) = 10 lbs/cubic foot
