Concrete Volume Reference Table

Unit Conversions

For calculations involving concrete footings, these key unit relationships are essential:

• 1 cubic yard (cy) = 27 cubic feet
• 1 foot (ft) = 12 inches (in)

Note: The formula v = 0.0031 l w t uses length and width in feet but depth in inches. This conversion factor (0.0031) accounts for the mixed units and converts the final volume to cubic yards.
