Measure separate, non-overlapping sections.

Changing units clears the dimensions to avoid reinterpreting your measurements.

Know what is included

This calculator totals rectangular sections only. Exclude overlapping areas. Curved shapes, bags, reinforcement, mix design, structural checks and prices are not included.

Volume = length × width × thickness × quantity. All dimensions are converted to meters before calculating. 1 yard = 0.9144 meters; 1 yd³ = 0.764554857984 m³. Totals use unrounded values; the display rounds to three decimal places.
