FAQs
How do you calculate the weight of granite?
Multiply the length × width × thickness (in meters) to get volume in cubic meters, then multiply by granite density (kg/m³).
How much does granite weigh by size?
Weight depends on size and thickness. For example, a 1m × 1m × 3cm granite slab weighs about 85.5 kg (using 2850 kg/m³).
What is the weight of granite?
On average, granite weighs between 2700–3000 kg per cubic meter, depending on its density and color.
How much does 1.5 inch granite weigh?
A 1.5-inch (≈3.8 cm) granite slab weighs around 95–100 kg per square meter, depending on density.
