Sand Calculator
Calculate sand quantity in cubic metres, kg and tons for concrete or mortar.
📐 Dry Volume = Wet Volume × 1.54 · Sand Volume = Dry Volume × (sand ratio ÷ sum of ratio) · Weight = Volume × 1600 kg/m³
The sand calculator estimates the volume and weight of sand (river sand, M-sand, or fill sand) needed for construction — plastering, brickwork mortar, concrete, and flooring screed. It also converts between units (cubic metres, cubic feet, tonnes, and kg) since sand is sold differently by different suppliers: cubic feet at the material yard, tonnes by weight, or cubic metres for large quantities.
📋 How to Use This Calculator
Select the application (plastering, mortar, concrete, backfilling, or flooring). Enter the area and thickness (for slab/plaster) or volume (for mixing). The calculator shows sand volume in cubic metres and cubic feet, weight in tonnes and kg, and the number of standard trucks needed. Cost estimation uses current market sand prices.
💡 Key Facts & Information
Sand unit conversions: 1 cubic metre = 35.315 cubic feet. Density of dry river sand: 1,440–1,600 kg/m³. Density of M-sand: ~1,550 kg/m³. Loose sand is 10–15% less dense than compacted. Volume increase when wet: 10–20% (bulking of sand). Standard tractor load: 90–100 cubic feet in most Indian cities. Truck (6-wheeler): 200–250 cubic feet. Common sand types: river sand (regulated and sometimes banned); M-sand (manufactured sand from crushed stone, mandated in several states including Karnataka, Tamil Nadu); pit sand (used for filling). M-sand prices: ₹40–80 per cubic foot depending on city.
