Introduction
Read this article to find out how to perform some useful concrete calculations. The concrete cubic yard formula is one of the most useful, and can be used by engineers, contractors, and anyone else working with concrete; it doesn’t require intense mathematics of any sort. A bags of concrete calculator is also linked, though this can easily be calculated from the provided formula. Read on further to find out how much concrete weighs.

The concrete cubic yards formula is a formula of volume, and as such requires three dimensions: length, width, and depth. This formula can be used for many applications, such as pouring a foundation or a driveway. Follow the steps below to calculate the total number of cubic yards required.
- To start with, you’ll need to obtain these measurements with a measuring tape or some other device. Make sure to record all measurements in feet. Record length, width, and depth. Divide any inch measurements by 12 to get everything into feet.
- Multiply all measurements together, as: length * width * depth. This will give a result in cubic feet.
- To measure footings, add up the total length of the footings, then multiply by the width and depth. For instance, if you were pouring footings for a 10 ft. x 10 ft. shed, you would multiply the length (10 ft.) by the number of sides (4), and then multiply that result by the width of the footings, say 16 inches, which is 16/12=1.33 feet. So the area of the footings would be 10 * 4 * 1.33. Then just multiply by the depth of the footings to get the volume of concrete.
- Add up all the volumes you’ve calculated, then divide by 27 to get cubic yards. The reason for dividing by 27 is that there are 3 feet in a yard, so that in a cubic yard there are 3 * 3 * 3 = 27 cubic feet.
Cement trucks typically hold anywhere from 8 to 14 cubic yards of concrete, so use the cubic yard calculation to determine how many truckloads will be required. This foundation calculator may be useful for more complex calculations.
The reason for calculating in yards is that concrete bags are usually sold according to cubic yards. It is best to round up your calculations to the nearest half-yard, so that there is some room for error.
Bags Concrete Calculator
To calculate the number of bags of concrete, first calculate the total yardage as above. Then, use the conversion table below to figure out how many bags to buy.
- Ninety forty-pound bags equal 1 cubic yard of concrete
- Sixty sixty-pound bags equal 1 cubic yard of concrete
- Forty-five eight-pound bags equal 1 cubic yard of concrete
- Or more generally: 1 cubic yard of concrete equals 3600 pounds of concrete.
How much does concrete weigh?
As shown above, it takes 3600 pounds of concrete bags to make a cubic yard of concrete. However, this is not necessarily the weight of the concrete, as the bags are mixed with other things to make up concrete.
The density of concrete can vary substantially depending on the application it is to be used for. The approximate density, though, is 150 pounds/ft3, or 4050 pounds/yd3. In metric units, that’s 2400 kg/m3. Lightweight concrete weighs 1750 kg/m3. In English units, that’s about 109 lb/ft3 or 2950 lb/yd3. Make sure to look up the density of your specific blend of concrete, though, rather than relying on these figures.
Conclusion
The above calculations are very useful to anyone pouring concrete. It is best to understand the calculations involved rather than simply relying on online calculations; this helps us realize when a number does or doesn’t make sense. If you understand how much a cubic yard of concrete really is, you may be more likely to realize you’ve made a mistake if you calculate a large cubic yardage of concrete.

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.
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
To measure for concrete use the formula for calculating the volume for concrete requires using three dimensions: length times width (which is area) times the height (thickness) or L x W x H. If you are using feet as your standard unit of measurement, this formula will give you the volume of concrete in cubic feet.
Steps to measure for concrete, proceeds as follows: 1) Take the all dimensions of concrete structure in feet, 2) multiply the Length times width times thickness to determine volume in cubic feet, 3) divide the resulting number by 27 to get volume in cubic yards.
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 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.
