The density or specific gravity of granite is about 2.6-2.9 tons per cubic meter
The density or specific gravity of marble is about 2.5 tons per cubic meter
Calculation of stone weight: stone volume or cubic * density or specific gravity
That is: length * width * thickness * specific gravity = stone weight
If you want to know the freight price of each stone (from the source to the place of use)
Calculation method: length * width * height * proportion * ton / price = price of each stone
（1） Talent product calculation:
1 talent = 303 × 303mm; 1 Ping = 36 talent; 1 m2 = 10.89 talent = 0.3025 Ping
Calculation of talent product: length (m) × width (m) × 10.89 = talent
For example: 3.24M long and 5.62m wide, the product is calculated as follows:
3.24 × 5.62 × 10.89 = 198.294, then = 5.508
（2） Thickness calculation:
1. Calculated by cm (CM): 1cm (CM): 10 m m (mm): 0.01M (m)
(1) Common thickness of granite: 15 mm, 19 mm, 25 mm, 30 mm, 50 mm
(2) Common thickness of marble: 20mm, 30mm, 40mm
(3) Common thickness of Roman granite and imported granite: 12mm, 19mm
2. Calculated in points:
1 point = 1 / 8 inch = 3.2mm (commonly known as 3mm)
4 points = 4 / 8 inch = 12.8mm (commonly known as 12mm)
5 points = 5 / 8 inch = 16 mm (commonly known as 15 mm)
6 points = 6 / 8 inch = 19.2mm (commonly known as 19mm)
（3） Weight calculation:
1. Granite and marble: 5 points = 4.5kg; 6 points = 5kg; 3cm = 7.5kg
2. Roman granite: 4 points = 2.8kg; 6 points = 4.4kg
Attached small question and answer: what is the product?
A: Chi Ji is the customary term for overseas Chinese in Taiwan and some Southeast Asian countries, that is, the volume indicated by cubic feet. And we usually say the volume (in cubic meters) conversion, multiplied by 35.32.
