Slab Concrete Calculator

Step 1: Select Measurement Unit

Choose between meters (m) or feet (ft) based on your preference. The calculator will handle all conversions automatically.

Step 2: Enter Slab Dimensions

Input the length, width, and thickness of your slab. You can use the thickness presets for common slab sizes (4 inches, 6 inches, 10 cm, 15 cm, etc.).

Example: For a 10m × 5m slab with 0.1m thickness, enter: Length=10, Width=5, Thickness=0.1

Step 3: Enable Cost Estimation (Optional)

If you want to estimate the total cost, enable cost estimation and enter the price per cubic meter of concrete in your area.

Step 4: View Results

The calculator instantly displays the concrete volume in multiple units (m³, ft³, yd³), slab area, and optional cost estimate. You can copy, save, or export the results.

How much concrete do I need for a 10×10 slab?

For a 10m × 10m slab with standard 0.1m (4 inch) thickness, you'll need 10 cubic meters of concrete. For a 10ft × 10ft slab with 4 inch thickness, you'll need approximately 1.23 cubic yards.

What thickness should my concrete slab be?

Standard residential slabs are typically 4 inches (10 cm) thick. For heavier loads like garages, use 6 inches (15 cm). Industrial applications may require 8 inches (20 cm) or more. Always consult local building codes.

How do I convert cubic meters to cubic yards?

Multiply cubic meters by 1.30795 to get cubic yards. The calculator automatically shows results in all common units (m³, ft³, yd³).

Should I order extra concrete?

Yes, always order 5-10% extra to account for spillage, uneven ground, and measurement variations. It's better to have slightly too much than to run short during pouring.
