Select Shape

Notes:

  • Add 10% to your final quantity to account for waste and variations
  • One cubic yard = 27 cubic feet
  • Standard concrete mix: 1 part cement, 2 parts sand, 3 parts aggregate
  • Higher PSI ratings require more cement in the mix
  • Consider weather conditions and curing requirements

Concrete Calculator

The Concrete Calculator helps estimate the amount of concrete needed for different types of construction projects. It ensures that you purchase the correct amount, reducing waste and extra costs.

Formula:

Volume (cubic feet) = Length × Width × Depth

Volume (cubic yards) = Volume (cubic feet) ÷ 27

How to Use the Concrete Calculator

  • Select the shape of the structure you are working on (slab, wall, footing, or circular column).
  • Enter the required dimensions such as length, width, thickness, or height.
  • Choose the concrete grade based on the project’s requirements.
  • Click "Calculate Volume" to get an estimate of the concrete needed.
  • Adjust values to compare different scenarios and ensure accuracy.

Why Use a Concrete Calculator?

  • Prevents over-ordering or running short on concrete.
  • Helps budget construction materials efficiently.
  • Reduces waste and minimizes project costs.
  • Provides instant calculations for better planning.

FAQ

What is a concrete grade?

Concrete grade refers to the strength of concrete measured in PSI (pounds per square inch). Different grades are used for different types of construction.

Why should I add extra concrete?

It is recommended to add about 10% extra to account for variations in mixing, spills, and uneven surfaces.

How do I convert cubic feet to cubic yards?

Since 1 cubic yard equals 27 cubic feet, divide the total cubic feet by 27 to get the volume in cubic yards.

Can this calculator be used for different types of concrete work?

Yes, the calculator works for slabs, walls, footings, and circular columns, making it versatile for various construction needs.
