Concrete volume calculator
Calculate concrete in cubic metres and litres from rectangular dimensions, quantity and an optional waste allowance.
Quantity estimate for rectangular shapes only, not structural design. Bag counts require the yield of your specific mix and are not calculated here.
Your answer will appear here.
Help and method
Convert depth from centimetres to metres by dividing by 100. Multiply length × width × depth × quantity for the base volume, then multiply by (1 + waste percentage / 100). One cubic metre equals 1,000 litres. All items use the same dimensions. Limits: length and width 0.000001–10,000 m; depth 0.000001–10,000 cm; quantity 1–1,000,000 whole numbers; extra allowance 0–100%. Result up to 1,000,000,000 m³. Nonzero inputs must be at least 0.000001.
