# Calculate granite weight

Calculating the weight of granite is essential. In particular, in free-standing floors and for installation as work or table tops, the substructure must be designed for the weight load. In addition, the weight is important for the planning and execution of the transport.

### Geometric basic formulas

In order to calculate the weight of granite, a few mathematical calculations are necessary to calculate area and space.

• For square / rectangular areas: length x width
• For round surfaces: radius squared times pi (3.1415)
• For square / rectangular volumes: length x width x height
• For round volumes: radius square times Pi x height

With these formulas, the spatial volumes of the granite are calculated in cubic centimeters. The result must then be multiplied by the density of the granite to get a weight indication. The calculation unit is cubic centimeters. The unit of measurement of the calculated volume must, if not yet done, be converted into cubic centimeters.

The average density of one centimeter thick granite is 2.8 grams per cubic centimeter. The calculated cubic centimeters of volume are multiplied by the density. The result of the weight is the weight of the granite in grams. Of course, it is also possible to adapt the calculation to higher arithmetic units.

• Granite density 2.8 kg on a cubic decimeter
• Granite density 2800 kilograms per cubic meter

### Different densities

There are many types of granite, which also have different densities. With the standard density of 2.8 grams per cubic centimeter, the weight calculation is common. For more accurate results, more accurate densities of the granite species can be used.

• China Gold, 2.6 to 2.75 grams (g) per cubic centimeter (cc)
• Padang Crystal, 2.65 g / cc
• Shidao Red, 2.63 to 2.75g / cc
• Pearl Flower, 3.04 g / cm³
• Padang Rosa, 2.75 to 2.9 g / cm³

### Tips & Tricks

For common household quantities, for example, to prove soil with granite, the general density average is sufficient as a calculation factor.
