Formula used
Volume
- Block/slab:
V = L × W × T - Cylinder:
V = π × (D/2)² × H - Sphere:
V = (4/3) × π × (D/2)³ - Irregular: measured or known volume
Mass: m = ρ × V
Weight (force): W = m × g where g = 9.80665 m/s²

FAQs
Use the preset closest to your stone. For exact projects, obtain density from supplier datasheets or perform a water-displacement test to determine volume and compute density.
Mass measures the amount of matter (kg, lb). Weight is a force due to gravity (kN, lbf). This tool outputs both so you can use the most appropriate measure for your task.
Bulk aggregates include voids between particles, lowering bulk density compared with solid rock. Select an aggregate preset when estimating truckloads or handling loose material.
Yes. Switching unit system updates field labels and density unit automatically. You may recalc to see outputs in both metric and US customary units.
Presets are typical values. Natural stone varies by quarry and moisture. For critical lifts or structural checks, use certified values from your supplier and include safety factors.
No. The calculator estimates stone only. Add additional mass for pallets, straps, mortar, reinforcement, or fixtures as needed for logistics planning.
