Concrete Calculator SF to Yards Formula:
Definition: This calculator converts an area in square feet and a thickness in feet to the volume of concrete in cubic yards.
Purpose: It helps contractors, builders, and DIY enthusiasts determine the volume of concrete needed for a project.
The calculator uses the formula:
Where:
Explanation: The area in square feet is multiplied by the thickness in feet, then divided by 27 to convert to cubic yards.
Details: Knowing the volume of concrete is crucial for ordering the correct amount, planning construction, and estimating costs accurately.
Tips: Enter the area in square feet and the thickness in feet (both must be > 0). The calculator computes the volume in cubic yards, rounded to 3 decimal places.
Q1: Why is the result in cubic yards?
A: Cubic yards are a standard unit for measuring concrete volume, especially for ordering and transportation.
Q2: How do I find the area and thickness?
A: Measure the length and width of the area in feet to calculate square feet. Measure the thickness in feet based on your project requirements.
Q3: Can I use inches for thickness?
A: Yes, but convert inches to feet by dividing by 12 before entering the value.
Q4: Is the formula accurate?
A: Yes, it accurately converts square feet and thickness to cubic yards using the standard conversion factor of 27.
Q5: Does this include waste?
A: No, this is a base calculation. Add 5-10% extra volume before ordering to account for waste or spillage.
