What Does A Glass Box Mean? What’s A Glass Box

The glass standard box is no longer used, and the weight box is used, which means: 1 heavy box = 50 kilograms of glass. The unit of measurement originally developed by the state administration was “standard box”, which was changed to “weight box” more than 20 years ago for factory cost accounting. Now many enterprises have begun to “ton” as an accounting unit.

The calculated density of glass is 2.5. The conversion method between the area and the heavy box is: area (square meters) * thickness (mm) *2.5/50 = heavy box.

For example, the weight of 100 square 12mm glass is: 100*12*2.5/50 = 60 heavy boxes.

4mm 1 heavy box = 5 square

5mm 1 heavy box = 4 square

6mm 1 heavy box = 3.333 square

8mm 1 heavy box = 2.5 square

10mm 1 heavy box = 2 square A box is a unit of quantity of glass. The measurement method of ordinary flat glass is generally calculated by “weight box”, which is a unit of measurement for calculating the materials and costs of flat glass. A unit of measurement for flat glass materials and costs. A weight box is equal to the weight of 10 square pieces of 2mm thick flat glass (weighs about 50kg). Think of glass as a cube, with weight equal to volume times specific gravity.

Calculate the volume, the volume of 10 square plates of 2mm thick glass is: 0.002m×10㎡=0.02 cubic meters; Calculate the specific gravity, the specific gravity of glass is: 2500 kg/cubic meter, which is a constant.

Calculate the weight, 2mm thick flat glass 10 square weight is: 0.02 cubic meters ×2500 kg/cubic meter =50kg; Comprehensive, (0.002m×10㎡) ×2500kg/ cubic meter =50kg.
