Concrete is a special construction material that is prepared by a mixture of cement, water, and aggregates such as sand, gravel, or crushed stone. Traditionally concrete is a mixture of cement, sand, gravel, and aggregate in water. The concrete bags are usually 40 pounds, 60 pounds, and 80 pounds in size. The number of bags varies in the yard by increasing or decreasing the size of the bags. If you are calculating several concrete bags in a yard, then it all depends upon the size of a bag. 

How Much Concrete Do I Need?

If a concrete bag is equal to 40 lb then how many bags do I need for 1 yard of concrete


40lb bag = 0.64 ft^3

1 Cubic Ft. = 62.41 Lbs.


1 lb = 0.016 ft^3

Now we know that 

 3 ft = 1 yard

27 ft^3 = 1 yard^3


1 yard^3 = 27 ft^3

So to get how many bags of concrete are required to fill a volume of 1 yard. If each bag is 40lb then:

 1 yard^3 = 27/0.64 

 1 yard^3 = 27/0.64 

 1 yard^3 = 42 Bags

You can find the number of yards of concrete with the concrete calculator

Why Measure Concrete in Yards?

Concrete is often measured in cubic yards and allows an easier way to measure the required amount of concrete. A cubic Yard is a unit of volume and it provides a more accurate estimation compared to another unit. There are specific dimensions of concrete quantity. 

By measuring quantity in cubic yards, you can easily measure the volume of concrete relative to the dimension. Measuring concrete in yards has several benefits in the construction industry. The yard is a standard unit in the construction industry and easier to communicate. Yards are a simple way to understand. 

Reason to Measure Concrete in Yards

Suppose you need to file a place with concrete 10 feet long, 5 feet wide, and 3 feet high, the volume of concrete would be

10 Feet x 5 Feet x 3 Feet = 150 Cubic Feet

Now to convert this volume of concrete into cubic yards, you simply need to divide it by 27. 

1 Cubic Yard = 27 Cubic Feet


150 cubic feet / 27 = 5.56 cubic yards

The concrete calculator readily measures the quantity of concrete in cubic yards. Yards are specific units for estimating the quantity of concrete for a project.

Benefits of Cubic Yard

There are multiple benefits of measuring concrete in cubic yards. 

Standardized Unit

Yards are standardized units of measurement in the construction industry. Make it easier unit to communicate and compare concrete quantity for various projects and locations.

Accurate Measurements 

Concrete is a liquid material when it is compiled and you can measure it in volume. Yards are a unit of volume and you can measure the quantity of concrete more accurately in yards. 


Yards are compatible with the batch size used in the production of concrete. So it is easier to calculate several yards required in construction projects. 

Industrial Standard

Yard is an industrial standard for measuring concrete quantity. Engineers do use yards for measuring the quantity required for specific projects


A yard is a standard unit for measuring concrete and its quantity. The other reason cubic yard is a unit of volume and you need a unit of volume for concrete measurement. Yards measuring the quantity of concrete more precisely compared to any other unit like Kg, or lb. The other thing bag sizes may vary in different parts of the world.
