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 you estimate the amount of concrete needed for various construction projects. It makes sure you buy the right amount, cutting down on 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’re working on (slab, wall, footing, or circular column).
  • Input the required dimensions like length, width, thickness, or height.
  • Choose the concrete grade based on your project’s needs.
  • Click "Calculate Volume" to get an estimate of the concrete required.
  • Adjust values to compare different scenarios and ensure accuracy.

Why Use a Concrete Calculator?

  • Prevents over-ordering or running short on concrete.
  • Helps you budget for construction materials effectively.
  • Reduces waste and keeps project costs down.
  • 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 various types of construction.

Why should I add extra concrete?

It’s advisable 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 is suitable for slabs, walls, footings, and circular columns, making it versatile for various construction needs.
