Hello guys, In this article, you will learn how to calculate the weight of concrete in a cubic foot. We do not measure the dimension of all structures like column, beam, slab, etc in meters. Sometimes we have to measure in the foot. So, we have to calculate the weight of concrete which has volume in a foot cube.
By the way, the weight of concrete may depend upon the grade of concrete. The gradient used in the concrete highly affects the density of concrete which change the weight of concrete.
So, lets start how to calculate Step by Step.
Let us take an example of one cubic foot of concrete. Latter if have 5 cubic foot or 10 cubic feet then you could calculate in the same process.

Numerical Calculation for Weight of concrete per cubic foot
Step-1 (Convert Foot into Meter)
We have weight of concrete,
= Volume * Density
But, we have density of concrete = 2400 kg/m3
(Keep in mind that density of PCC (Where Steel rod has not used in concrete) is 2400 kg/m3 but density of RCC (Where Steel rod has used in concrete) is 2400 kg/m3 )
And, Volume of concrete,
= 1 feet * 1 Feet * 1 Feet
= 0.3048 m * 0.3048 m * 0.3048 m
Since, we have 1 foot = 0.3048 m. We have to convert all the foot units into meter.
= 0.0283 m3
Therefore,
Step-2 (Apply Formula Taking Density 2400 kg/m3
Weight of Concrete Cube will be,
= Volume * Density
= 0.0283 * 2400
= 67.9604 Kg.
