Concrete Volume Calculator
Calculate how much concrete you need in cubic yards or cubic meters.
Enter length, width, and depth to get accurate concrete volume estimates.
Concrete Needed
Concrete Volume is calculated by multiplying the three dimensions of the area to be filled, then converting to the desired unit.
Volume = Length × Width × Depth
Unit conversions:
Cubic Yards = (Length ft × Width ft × Depth ft) / 27Cubic Meters = Length m × Width m × Depth m
Practical tips (imperial):
- Always order 5–10% extra to account for spillage, uneven ground, and over-excavation
- One cubic yard covers about 81 sq ft at 4 inches deep
- Standard slab thickness: 4 inches (residential), 6 inches (garage/driveway)
- A typical 60 lb bag of concrete mix yields about 0.45 cubic feet
Practical tips (metric):
- Always order 5–10% extra to account for spillage, uneven ground, and over-excavation
- One cubic meter covers about 10 m² at 10 cm deep
- Standard slab thickness: 10 cm (residential), 15 cm (garage/driveway)
- A typical 25 kg bag of concrete mix yields about 0.012 cubic meters
- A 50 kg bag yields about 0.024 cubic meters
