At the end of 2003, RMB savings amounted to 11 trillion yuan?

1.1X10^13
That is, 1.1 times 10 to the 13th power
Scientific counting method, that is, a number greater than 1 and less than 10 times the XX power of 10

1.18 billion scientific counting

1180 million = 1180 million
1180000000=1.18x10^9

1104 million in scientific counting

1.104 * 10 12th power

How many hundred million kilometers is 108.21 million kilometers

108.21 million km

36185.4 million yuan = () billion yuan, about () billion yuan, 48908 million km = () billion km, about () billion km

36185.4 million yuan = (36.185.4) billion yuan, about equal to (36.2) billion yuan
48908 million km = (48.908) billion km, about equal to (48.9) billion km

How many billion kilometers is 1936420000 kilometers

1936420000 km = 1.936442 billion km

How many nanometers is a millimeter

1000000nm

How many decimeters is one nanometer

One nanometer is equal to one billionth of a meter in length. 10 ^ - 9, 10 is minus nine square meters

How many nanometers is one meter

1 nm is 10-9 M
So 1 meter is equal to 10 to the 9th nanometer, and it is equal to 1000000000 nanometer
