four numbers.
It depends on what material and how many there are in the bundle.
A standard bundle of 10 mm steel bars typically contains around 100 to 150 pieces, depending on the manufacturer and regional standards. The total weight of the bundle can vary, but it generally ranges from 1,000 to 1,500 kilograms (approximately 2,200 to 3,300 pounds). It's always best to check with the supplier for specific bundle sizes and weights.
8.8 is a quality measurement, 20 mm is a size measurement. They're not dependent on each other. You can have a 20 mm bar in any quality, as you can have an 8.8 quality bar in any size.
20 mm
It would take 20 pieces of 3 mm thick paper to make a stack that is 6 cm thick. This is because 1 cm is equal to 10 mm, so each piece of paper adds 3 mm to the height of the stack.
20 mm should still be 20 mm!
All U.S. bills are approximately 0.11 mm thick. I.e. a stack of 9 of them is about 1 mm high. In inches, a single bill is about 0.0043 inches thick. A standard bundle of 50 bills ($50 to $5000) is about 5.5. mm high (0.215 in at 233 to the inch).
None but 20 mm = 2 cm
10m (10,000 mm) of water column is about 0.98 bar (P=density*specific gravity*height=1000*9.8*10) 5000 mm WC is 0.49 bar then.
20 mm - 0.2mm = 19.8
0.001. because a micron is 1000 times smaller than a millimetre
20 millimeters=0.78 inches Direct Conversion Formula 20 mm* 1 in 25.4 mm = 0.7874015748 in
