Our Concrete Calculator calculates the amount of concrete you might need for your project! 

The foundation of every construction project relies on using the right amount of construction materials. Concrete, being one of the crucial materials in the construction project, should be used in an accurate volume. Using more or less, both create an issue for you in expense and quality. 

At this, you would actually need a tool that can help you know the right volume of Concrete to assess your needs. 

Our free online concrete calculator solves this issue for you. It calculates the concrete volume required for your projects, thus easing the planning and saving you time.

Concrete & Our Concrete Calculator

Concrete is a composite material formed by mixing gravel, sand, and crushed stone with fluid and cement. The mixture hardens over time with the hydration process. This is the second most used substance on earth and is widely used in construction projects. 

This construction material is famous for its strength. This makes it a firm pillar of every construction project. It can handle heavy loads, resist weather changes, and last for decades if prepared and maintained properly

Our concrete calculator is a free and online tool available to calculate the volume of concrete for any construction project. You have to enter the length, width, and depth, and it will give you the exact estimated weight of concrete needed to cover a given area. The answer you get will be in three separate units: cubic yards, cubic feet, and cubic meters. 

Moreover, it will also guide you on the volume needed for pre-mixed concrete and the bags of concrete with the concrete bag calculator.

You should also understand that Concrete is available in different modes depending on the project size:

• Pre-packed bags – Usually sold in 60 or 80-pound bags for small works.
• Ready-mix delivery – Supplied by mixer trucks for large construction sites.
• Precast products – Manufactured in factories on demand and orders for slabs, pipes, and walls.

Using Concrete Calculator 

Concrete and calculators always go hand in hand when you plan any construction work. You cannot guess the amount of concrete because even a small error can affect your project.

Our concrete calculator works for different projects. Here you will find the calculators for different surfaces. You have to select the type of surface, add the required measurements, and get an estimate of the material.

With this, you can order the right amount of concrete and avoid wasting money on extra material, and prevent delays caused by ordering too little. With this tool, planning your project becomes easier. 

Concrete Slab Calculator

A concrete slab calculator helps you find out how much concrete is needed for floors, driveways, patios, or any flat surface. It includes slabs, square footings, and walls.

Steps:

• Enter the length in any of the units, which are feet, inches, yards, meters, or centimetres
• Enter the width in the same unit.
• Enter the thickness or height in inches.
• Add the quantity of the slab needed.
• Calculate. 

The total volume of concrete needed for such a surface will appear.

Example 

Concrete for a 10×10 Slab

If the thickness is 4 inches, it requires 1.24 cubic yards of concrete. This equals approximately 56 bags of 80 lb concrete.

Similarly, for a 6-inch thickness, 1.85 cubic yards of concrete is needed, which is about 84 bags.

Use our calculator to adjust for other dimensions.

• Calculate.

You will get the answer in the form of the number of bags you need to buy. Use this to plan your purchase and avoid over-ordering.

Important Tips for Concrete Bags Calculation

• Each 80 lb bag = 0.022 cubic yards
• For a 100 sq. ft. slab, 4 inches thick is about 56 bags
• From a 50 lb bag, you will get 0.375 cubic feet of Concrete

Concrete Price Calculator

Our concrete price calculator estimates the total cost of Concrete based on volume and price per unit.

Steps:

• Enter the volume of concrete needed for construction.
• Add the price per cubic yard or per cubic meter based on supplier rates.
• Enter any extra costs, such as delivery or labour, if needed.

The total cost of Concrete for your project will appear.

Concrete Weight

The weight of 1 cubic yard of Concrete is nearly 4,000 lbs. This is equal to 2 tons.

When you are weighing four cubic yards of concrete, this is 16,000 lbs.

A slab measuring 10 x 10 and 4 inches in depth requires just one cubic yard of concrete.

Standard Thickness of Concrete

The required thickness depends on usage:

• 4 inches – Patios, walkways, and basic residential slabs
• 5 – 6 inches – Garage floors and heavy driveways
• 6 – 8 inches or above – Commercial and industrial slabs

How Do I Calculate The Concrete Volume I Need?

If you are an expert constructor or builder, you have the idea of the amount of concrete you will need to complete the project. Most contractors do the calculation manually, too. However, if you are new to this field or want to save your time and effort, you can calculate your concrete needs through our Concrete Calculator. 

For this, you need the length, width, and thickness of your area. Once you have measured the three dimensions, enter these in the calculator to get the estimate.

Concrete Calculator Formula

If you are calculating manually, there is a simple formula that can make your calculation easy. Moreover, calculators also use this formula to assess the material needed.

The one simple formula is:

Length × Width × Thickness = Volume

If you are calculating manually using this formula, your result will be in cubic feet. 

Your next step is to turn the volume into cubic yards. 

To do this, divide it by 27 because one cubic yard equals 27 cubic feet. 

It is a must to do so because most concrete suppliers measure concrete in cubic feet. For this, the result must be converted from yards to cubic feet.

The length, width, and thickness are the measurements of the space that needs to be constructed using Concrete.

This formula is mainly used for slabs, walls, steps, columns, or any shape that you can divide into simple sections. It gives you a fast estimate for how much concrete to order.

For round areas, such as circular footings or posts, the formula is different. 

π × (radius x radius)

This gives you the area of the circle in square feet. To find the volume, multiply that area by the thickness or height of the footing. The result will be in cubic feet. Divide 27 by it and convert it to cubic yards.

A Short Explanation with Example

If the Diameter is two feet, the Radius = 1 foot

Thickness = 3 feet

Area = π × (1 × 1)

= 3.14 x 1 = 3.14 sq. ft

Volume = 3.14 × 3 = 9.42 cubic feet

Conversion to cubic yards 

9.42 ÷ 27 = 0.35 cubic yards

This is how you can find out the concrete volume for a circular area.

If you want such results without too much manual calculation, use our online concrete calculator.
