explain with examples : smaller lengths and bigger lengths

Answer: mm is thesmaller length example - sand particles
Step-by-step explanation:
Answer:
Here is an illustration of sizes, from the very small (a Quark) to the very large (the known Universe):
length continuum
The sizes are in meters using metric numbers.
(Just add the word "meter" after them, so we get "millimeter", "terameter", etc.)
Examples:
A Quark is about a femtometer in size.
Cells are about a micrometer in size (many different sizes though!)
The Milky Way is about a zettameter in size.
The Numbers
The numbers (like 106) use Scientific Notation to show how big the value is.
Example: 106 means to use 10 in a multiplication 6 times:
10 × 10 × 10 × 10 × 10 × 10 = 1,000,000
But in practice it is easier to think "a 1 followed by 6 zeros"
Which is a million.
The prefix is mega-, so a megameter is a million meters.
Example: 109 is a 1 followed by 9 zeros: 1,000,000,000 (a billion).
The prefix is giga-, so a gigameter is a billion meters.
Example: 10-9 is a 1 moved nine places the other side of the decimal: 0.000 000 001
It is also called a billionth.
The prefix is nano-, so a nanometer is a billionth of a meter.
Looking at the illustration we can see that a person is about 1 meter in size, a mountain is about 103 (one thousand) meters in size, and the diameter of the Sun is about 109 (one billion) meters.
Example: We could also say the Sun is about a "gigameter" in size
It's diameter is actually 1.392×109 meters, or 1.392 gigameters, or simply 1.392 Gm
