# How to use a concrete calculator to measure the yards of concrete

Construction Software The concrete calculator is used to work out the yards of concrete or how many pre-mixed bags of concrete are required to pour a slab, footing, column or post-fill project along with circular slab and patios. The cost of materials can be easily calculated if per yard price is provided.

Put the value of length, width, thickness as well as price per cubic yard (optional) and hit the calculate button.

Method to estimate concrete in yards

Concrete is sold with the cubic yard or in pre-mixed bags. A cubic yard is just a standard volume that is calculated in yards.

To measure a rectangular area, cubic yardage can be obtained by multiplying the project width, length and height in yards. For a circular patio or column, multiple the radius by 3.14 (πr2) with the height. Here, the measurements are given in yards.

The calculator can measure the required yards of concrete by providing the project dimensions in imperial or metric measurements along with inches, feet, yards, centimeters, or meters.

As for instance, a 10′ x 10′ slab that is 4″ thick will require an estimated 1.23 yards3 or 74 60lb bags of concrete and will cost approximately \$100.

Step by Step Guidelines for calculation devoid of a Calculator

• Calculate the length, width, and height of the slab, footing, or column. If the area is problematic or if multiple pours are required, split the project into smaller pieces and measure the concrete yardage of each separately. As for example, if it is required to calculate a slab that is not a rectangle or circle, split it into several sections and calculate the yardage of each section initially, then add the cubic yards together.

• Change dimensions to feet if they aren’t in feet. Change inches to feet, yards to feet or meters to feet.

• Multiply the width, length and height (W x L x H). The volume calculator (www.inchcalculator.com) can be applied to determine the cubic yardage of a space.

• Change the volume to cubic yardage from cubic feet by dividing the cubic footage with 27 to find the cubic yardage.

• Measure how many pre-mixed bags are required for smaller projects. For smaller projects, it is not necessary to order a truckload and pre-mixed bags of concrete. The bags of concrete can be brought from your local home center.

1. 90 40lb bags of concrete are required to fill one cubic yard of volume.
2. 60 60lb bags of concrete are required to fill one cubic yard of volume.
3. 45 80lb bags of concrete are required to fill one cubic yard of volume.

• Include 5%-10% extra material for settling, spillage, and waste. It confirms that the project can be accomplished in a single pour devoid of providing more concrete to accomplish the project if there is short quantity.

Formulas for measuring concrete in yards

Square and Rectangular Areas

volume = width × length × height
yds3 = width yds × length yds × height yds
yds3 = (width ft × length ft × height ft) / 27

Circular and Cylindrical Areas

volume = π × radius2 × height
yds3 = π × radius yds × radius yds × height yds
yds3 = (π × radius ft × radius ft × height ft) / 27 π = 3.14159265359

Steps: Break the steps into rectangles, then determine the volume for each rectangle/cube. Include the volume for each rectangle to get the total volume.

volume = width × length × height
yds3 = width yds × length yds × height yds
