The Ultimate Concrete Calculator (Cubic Meters, Cubic Yards, & Bags). You can also calculate both the volume and the number of concrete bags for various applications with the following engineering calculator: Note: It is important to use constant units in your calculations. The yield of concrete bags is estimated as shown in the following table.īy using this table, you can easily calculate the number of premixed concrete sacks you need for a specified volume. Step 2: Dividing the required calculated volume in step 1 by the yield
HOW MUCH CONCRETE DO I NEED HOW TO
To know more about how to calculate the volume of concrete for various applications and shapes, you can read the following article, “ Calculating Yards of Concrete: Explained“. In brief, you should divide these shapes into two or more regular shapes to simplify your volume calculations. In addition to the aforementioned regular shapes, irregular shapes also often exist in many concrete applications. Or, if you are calculating cubic meters of concrete, you should convert all the units from centimeters and millimeters to meters. Each 3 feet convert to one yard, and each 36 inches convert to one yard. For example, if you are calculating concrete yardage, you should convert all units from feet and inches to yards. It is important to note that the units should be consistent. The following table shows the volume formulas for different shapes. For example, the formula of determining the volume of a rectangular prism is simply length multiplied by width multiplied by thickness. In fact, its formula largely depends on the shape of the element.

The first step is to determine the volume of concrete. Step 1: Calculating the volume of concrete With this easy method, the yield is often assumed, unless tested or mentioned in the product’s specifications.īesides, it is important to note that our engineering tools and calculators, specifically the concrete volume and bag calculators, are integrated with more advanced methods for high accuracy and precision.
