Stone to accumulate, weight, thickness calculation method

(a) to accumulate computation.

1 just = 303 x ㎜ 303; 1 ping = 36 just;

1 square meters (㎡) = 10.89 just = 0.3025 apron

Just accumulate calculation: long (meters) x width (meters) x 10.89 = just

For example: long 324 meters, width 5.62 meters, its just accumulate computation and below

324 x 5.62 10.89 = 198.294 just =... 5.508 apron

(2) the weight calculation:

1. Granite, marble: 5 points = 4.5 ㎏; 6 points = 5 ㎏; 3 ㎝ = 7.5 ㎏

2. The Roman hillock stone: 4 points = 280 ㎏; 6 points = 4.4 ㎏

(3) thickness calculation:

1. ㎝) in centimeters (calculation: 1 cm (㎝) = 10 millimeters (㎜) = 0.01 meters (m)

(1) granite common thickness: 15 ㎜, 19 ㎜, 25, 30 ㎜ ㎜ ㎜, 50

(2) marble common thickness: 20 ㎜, 30 or 40 ㎜ ㎜

(3) Roman hillock stone, import hillock stone commonly used thickness: 12 ㎜ ㎜, 19

2. To points calculation: 1 cent = 1/8 inch = 3.2 ㎜ (appellative ㎜) 3

4 points = 4/8 inch = 1.28 ㎜ (appellative ㎜) 12

5 points = 5/8 inch = 16 ㎜ (appellative ㎜) 15

6 points = 6/8 inch = 19.2 ㎜ (appellative ㎜) 19
