Concrete Calculator

How do you figure the quantity of concrete?

• Dimensions of the volume you wish to pour are measured in cubic feet and then converted to cubic yards.
• 1 cubic yard = 27 cubic feet.

To calculate the volume of walls and flatwork, use the equation:

V = L x W x D / 27 ft³

Use the online calculation below to figure cubic yards for walls and flatwork.  All measurements should be entered in feet:

Length:	ft.
Width:	ft.
Depth:	ft.
Volume in Cubic Yards =	yd3

V = 3.14 r² x D / 27 ft³

Use the online calculation below to figure cubic yards for Caissons and Columns:

Diameter:	ft.
Depth:	ft.
Volume in Cubic Yards =	yd3
