To calculate the cubic yards of concrete needed for a project, you need to know the length, width, and depth (or thickness) of the area you want to pour concrete into. Here are the steps:
1. Measure the length, width, and depth of the area in feet. Make sure all measurements are in the same unit, typically feet.
2. Multiply the length by the width to find the area in square feet.
3. Multiply the area in square feet by the depth in feet to find the volume in cubic feet.
4. To convert the volume from cubic feet to cubic yards, divide by 27. There are 27 cubic feet in 1 cubic yard.
The formula for calculating cubic yards of concrete is: Cubic Yards = (Length × Width × Depth) / 27
For example, if you have a slab that is 10 feet long, 5 feet wide, and 0.5 feet (6 inches) deep, the calculation would be: Cubic Yards = (10 × 5 × 0.5) / 27 = 2.31 cubic yards. So, you would need approximately 2.31 cubic yards of concrete for this project.
Cubic yard is one of the most popular, oldest, non- standard unit based on imperial/ US customary measurement system used for measurement of volume of material which is widely used in United States, Canada and some Imperial states in United kingdom, do not very popular in European country and it is uncommon in Asian countries like India, Pakistan and Bangladesh, majority of the countries of world follows their SI standard unit for measuring the volume of material in cubic metre and litre.
Premix concrete is blended mix of Portland cement sand gravel and water with approved ingredient used for casting of different structure such as slab, patio, beam, column, foundation, retaining wall, ramp, sidewalk and etc. Basically concrete quantity in United States, Canada and in Imperial states, United Kingdom measured in cubic yards. So in this article we know about how to calculate cubic yards of concrete.
A cubic yard means volume of concrete that cover 3 feet long by 3 feet wide by 3 feet high, it is an Imperial / U.S. customary unit of volume, very much popular and mostly used in the United States and canada.
A cubic yard is defined as the volume of a cube with sides of 1 yard in length or 3 feet, 36 inches, 0.9144 meters. Generally a cubic yard look like heaped of material that spreading to cover 3 feet long by 3 feet wide by 3 feet depth.
How to calculate cubic yards
To calculate cubic yards, we use the formula: Cubic yards = Length (ft) x Width (ft) x Depth (ft) ÷ 27. Measure the length, width and depth of your area in feet and then multiply the figures together to calculate a result in cubic feet. You then divide the result by 27 will give you a total in cubic yards.
Formula for calculation of cubic yards: 1) Cubic yards = (Length in feet × Width in feet × Thickness in feet) ÷ 27, or 2) Cubic yards = (Square footage × Thickness in feet) ÷ 27, or 3) Cubic feet = Cubic feet ÷ 27.
How measure for concrete
Cubic yard formula
The formula for number of cubic yard = length (in feet) × width (in feet) × depth (in feet) ÷ 27, simply multiply the all three dimension length, width and their depth together to find the number of cubic feet, then divide by 27 to find the number of cubic yard.
● Volume in cu ft = length × width × height
● Formula for volume in cubic yard = length (in feet) × wide (in feet) × height (in feet) ÷ 27
Generally dimension of concrete slab measured in cubic feet, you need to convert cubic feet into cubic yard, you can easily calculate cubic yardage by converting all three dimensions of your material into yard and then you multiply.

How to calculate yards of concrete
To calculate yards of concrete, measure the area in feet. Multiply length by width, and then by thickness to determine cubic feet. Divide the resulting number by 27 or multiply by 0.037 to find cubic yards. Formula for yards of concrete = Cubic footage × 0.037.
Steps to calculate yards of concrete as follows:- 1) measure all dimensions (Length, width and thickness) of concrete slab in feet, 2) Multiply length by width, and then by thickness to determine cubic feet, 3) Divide the resulting number of cubic feet by 27 or multiply by 0.037 to find cubic yards.
How to calculate yards for concrete
To calculate yards for concrete, measure the area in feet. Multiply length by width, and then by thickness to determine cubic feet. Divide the resulting number by 27 or multiply by 0.037 to find cubic yards. Formula for yards of concrete = Cubic footage × 0.037.
How to calculate concrete yardage
To calculate concrete yardage, measure the area in feet. Multiply length by width, and then by thickness to determine cubic feet. Divide the resulting number by 27 or multiply by 0.037 to find cubic yards. Formula for concrete yardage = Cubic footage × 0.037.
How to figure cubic yards of concrete
To figure amount of cubic yards of concrete, measure the all dimensions of concrete solid slab in feet, then multiply length by width to get square footage, and then square footage multiply by thickness in feet to get volume in cubic feet, and divide the resulting number by 27 to find cubic yards of concrete.
For example:- To figure the yards of concrete for 10×10 slab at 4 inches thick-
1) Convert thickness of concrete slab in feet- 4 inches in feet = 4÷12 = 0.33 feet
2) Measure the square footage by multiplying length by width, 10’×10′ = 100 square footage
3) Multiply the square footage by thickness in feet = 100× 0.33 = 33 cubic feet
4) Divide the resulting cubic feet by 27 to find cubic yards of concrete, such as 33÷27 = 1.22 yards
Thus, you will need 1.22 cubic yards of concrete for 10 by 10 slab at 4 inches thick, 1.54 yards of concrete at 5″ thick, 1.85 yards of concrete at 6″ thick, 0.93 yards of concrete at 3″ thick, and 0.62 yards of concrete at 2″ thick.
How to calculate cubic yards of concrete
To calculate cubic yards of concrete, first multiply the length & width (in feet) of concrete slab to get square footage, then square footage multiply with their depth in feet to get cubic feet, then resulting cubic feet is divided by 27 to get volume of concrete slab in cubic yards.
● Square footage = length × width (in feet)
● Depth in feet = depth/12
● Volume of concrete slab in cubic feet = square footage × depth in feet
● Volume of concrete slab in cubic yards = volume in cubic feet ÷27 = number of cubic yards. This is your required quantity of concrete in cubic yards.
Suppose you have a standard concrete Patio of dimension 12 feet in length by 12 feet in width by 4 inches depth, then how to calculate cubic yards of concrete and how much concrete do you need for casting.

To calculate cubic yards of concrete for 12×12 slab at 4″ thick, you should follow the following solution steps:-
● Square footage = 12×12 = 144 sq ft
● 4″ depth in feet = 4/12 = 0.33 feet
● Volume of concrete slab in cubic feet = 144 sq ft × 0.33 feet = 47.52 cubic feet
● Volume of concrete slab in cubic yards = 47.52 ÷27 = 1.76 cubic yards. This is your required quantity of concrete in cubic yards.
Conclusion:-
To calculate amount of yards of concrete, measure the all dimensions of concrete solid slab in feet, then multiply length by width by thickness in feet to determine cubic feet, and divide the resulting number by 27 to find cubic yards of concrete.
