So what is the unit advance rate, what is the unit advance rate of the length unit?

The units of length are kilometers, meters, decimeters, centimeters, and millimeters, and the advance rate between kilometers and meters is 1000, and the advance rate between the other two adjacent units is 10.

Two counting units per adjacency.

The rate of progress between is (ten). We call this counting method decimal.

The decimal system is based on both bitimal and decimal digits.

Two principles, that is, all numbers are represented by 10 basic symbols, full decimal one, and at the same time, the same symbol represents different values in different positions, and the position of the symbol is very important. The basic symbols are ten numbers from 0 to 9.

To represent 10 times these ten numbers, shift the numbers to the left by one place and fill in the empty space with 0, i.e. 10, 20, 30 ,..90;If you want Minzhou to indicate 10 times of these ten numbers, you will continue to move the position of the numbers to the left, i.e., 100, 200, 300 ,..To represent the 1 10 of a number, move the number to the right, and fill in the empty space with 0 if needed

1 10 bits, 1 100 for 1 1000 bits.

This question focuses on the understanding of the generation and meaning of decimals.

When rewriting the name of the organization, it is necessary to use the progress rate. Method:

The number of high-level single-name advancement rate = the number of low-level single-name; The number of low-level single-name advancement rate = the number of high-level single-name number.

Extended information: The second is the basic unit of time in the International System of Units and the symbol is s. It is sometimes referred to as SEC by the English abbreviation.

Conversion of seconds. 1s = 10 3ms (milliseconds) = 10 6 s (microseconds) = 10 9ns (nanoseconds) = 10 12ps (picoseconds) = 10 15fs (femtoseconds) = 10 18as (attoseconds) = 10 21zm (thousand seconds) = 10 24ym (unit seconds).

Parsec is one of the oldest and most standard methods of measuring the distance between stars. It is based on trigonometric parallax. The inner angle of the triangle corresponding to the average radius of the Earth's orbit (one astronomical unit, au) as the base is called parallax.

When the size of this angle is 1 second, the length of one side of the triangle (since the difference in length between the two sides corresponding to the angle of 1 second is completely negligible, therefore, this triangle can be thought of as a right triangle or an isosceles triangle) is called a 1 second difference.

Common Time Unit Conversion:

1 second = 1000 milliseconds (ms).

1 second = 1,000,000 microseconds(s).

1 second = 1,000,000,000 Nanoseconds (ns) 1 second = 1,000,000,000,000,000 Picoseconds (ps) 1 second = 1,000,000,000,000,000 femtoseconds (fs) seconds, milliseconds, microseconds, nanoseconds, picoseconds, femtoseconds, and each of these two stages is converted to 1000.
