Concrete Volume Calculator
This concrete volume calculator reports every unit at once — cubic meters (m³), cubic yards, cubic feet and litres — so the same calculation works whether your supplier quotes yardage or metric volume.
Como usar esta calculadora
- Insira suas dimensões — pés para comprimentos, polegadas para a espessura.
- Ajuste as opções — porcentagem de desperdício, tamanho do saco e o preço local do concreto.
- Leia seus resultados — volume, sacos, peso e custo são atualizados ao vivo enquanto você digita.
A fórmula
Volume = L × W × T. Conversions: 1 yd³ = 27 ft³ = 0.7646 m³ = 764.6 L; 1 m³ = 1.308 yd³ = 35.31 ft³ = 1,000 L Exemplo resolvido: A 10 × 10 ft slab at 4 in = 33.3 ft³ = 1.23 yd³ = 0.94 m³ = 943 litres.
"How much concrete" is really a unit question: US ready-mix sells by the cubic yard (yardage), metric suppliers by the cubic meter, bagged products yield in cubic feet or litres. A concrete calculator m3 and yardage output side by side removes the conversion step entirely.
The concrete calculator cubic yards figure is your ordering number in the US — round up to the supplier's increment (usually 0.25 or 0.5 yd³). The concrete calculator cubic feet figure divides into bag yields, and litres map to metric bag yields.
For shape-specific volumes — circles, columns, trenches, stairs — every shape calculator on this site reports the same four-unit breakdown.
Perguntas frequentes
Perguntas comuns sobre a concrete volume calculator.
How do I calculate concrete volume?
Multiply length × width × thickness in a single unit. The calculator then converts among ft³, yd³, m³ and litres automatically.
How many cubic feet in a cubic yard?
27 ft³ = 1 yd³ (3 × 3 × 3 ft). One cubic yard also equals 0.7646 m³ or 764.6 litres.
What is concrete yardage?
Volume expressed in cubic yards — the standard US ready-mix ordering unit. This calculator's cubic-yards line is your yardage.
How many litres in a cubic meter?
1,000 litres. Metric bag yields are usually quoted in litres — a 25 kg bag yields about 12.5 L.
