1. The network will be upgraded to Constantinople & Petersburg at block height of 7280000. L, Z, b show that it will be upgraded on March 1, 2019 Beijing time. I don't know if the upgrade is successful
2. How can you like cm? You can ask your friends to like cm.
3. 1000 meters = 1000 meters = 10000 decimeters = 100000 centimeters
4. 100 cm is one meter, 500 cm is five meters
5. 1 nm = 10 ^ (- 9) m
1 cm = 10 ^ (- 2) m
therefore, 1 nm = 10 ^ (- 7) cm
that is, 1 nm = 10 billionth of a centimeter
nm is a unit of length, originally called nanometer, which is 10 ^ - 9 m (1 billionth of a meter), that is 10 ^ - 6 mm (1 millionth of a millimeter). Nanoscience and technology, sometimes referred to as nanotechnology, is to study the properties and applications of materials with structure sizes ranging from 1 to 100 nm. Nano effect refers to that nano materials have strange or abnormal physical and chemical properties that traditional materials don't have. For example, copper, which is originally conctive, will not conct electricity when it reaches a certain nanometer level limit, and silicon dioxide, crystal, which is originally insulated, will conct electricity when it reaches a certain nanometer level limit. This is e to the characteristics of nano materials, such as small particle size, large specific surface area, high surface energy, large proportion of surface atoms, and its unique three effects: surface effect, small size effect and macro quantum tunneling effect.

6. Inch for centimeter, this conversion, 1 inch = 2.5399918 cm, if you think it is right, please accept it, thank you.
7. Length unit and area unit cannot be converted to each other
length unit conversion:
1 kilometer (km) = 0.621 mile
1 meter (m) = 3.281 feet (FT) = 1.094 yards (YD)
1 centimeter (CM) = 0.394 inches (in)
1 angstrom (a) = 10-10 meters (m)
1 mile (mile) = 1.609 kilometers (km)
1 fathom (FM) = 1.829 (m)
1 foot (FT) = 0.3048 meters (m)
1 inch (in) = 2.54 centimeters (CM) < br />1 nautical mile = 1.852 km
1 chain = 66 feet (FT) = 20.1168 m
1 yard (YD) = 0.9144 m
1 mil = 0.0254 mm
1 foot (FT) = 12 inches (in)
1 yard (YD) = 3 feet (FT)
1 rod (RAD) = 16.5 feet (FT)
1 mile = 5280 feet (FT)
1 nautical mile (n mile) = 1.1516 miles
area unit conversion:
1 square centimeter Li (km-178;)= 100 ha = 247.1 acre = 0.386 square mile
1 square meter (M2) = 10.764 square feet (FT & # 178;)
1 hectare (are) = 100 square meters (M & # 178;)
1 hectare (HA) = 10000 square meters (M & # 178;)= 471 acre (acre)
1 square mile (mile & # 178;)= 590 square kilometers (km & # 178;)
1 acre (acre) = 0.4047 hectare (HA) = 4.047 × 10-3 square kilometers (km & # 178;)= 4047 square meters (m-178;)
1 square foot (FT & # 178;)= 093 square meters (M & # 178;)
1 square inch (in & # 178;)= 452 square centimeter (CM & # 178;)
1 square yard (YD & # 178;)= 8361 square meters (M & # 178;)

8. 1 m = 100 cm
so the conversion from m to cm is multiplied by 100
2.4 * 100 = 240 cm
so the conversion from m to cm is multiplied by 100
2.4 * 100 = 240 cm
