This Cubic Yard Calculator can calculate the cubic yards of a rectangular, triangular, or circular area. Just enter the length, width and depth values and click the Calculate button. For a circular area just enter the width and depth of the area, and no length.

A cubic yard is equal to 27 cubic feet. You can use this online calculator to determine how many cubic yards of material will be required for your project.

The formulas for the provided calculations are:
Cubic Yards of a Rectangular Area: ((Length x Width x Depth)/27)
Cubic Yards of a Triangular Area: (((Length / 2) x Width x Depth)/27)
Cubic Yards of a Round Area: ((3.1416 x (Width x Width) x Depth)/27)


Topsoil
Screened topsoil 1:1 - 1 cubic yard = 1 ton
Un-screened topsoil 1:1.3 - 1 cubic yard = 1 1/3 tons


Gravel
Bank run gravel 1:2
2" Screened gravel 1:2
1" and 2" Gravel 1:2
1 cubic yard = 2 tons

3"-6" oversized rock 1:1.5
8"-18" oversized rock 1:1.5
1 cubic yard = 1 1/2 tons


Crushed Aggregates
#1 Crushed limestone 1:1.5 - 1 cubic yard = 1 1/2 tons
#2 Crusher run limestone 1:2 - 1 cubic yard = 2 tons
