In 1960 an international body on weights and measures held a meeting to agree the basis for an international standard metric system.
As part of that process they agreed a system of standard prefixes that would apply to ALL weights and measurements to indicate the multiple involved of the basic unit concerned.
These are the prefixes that precede the SI units (abbreviated SI from the French name: Le Système international d'unités) sich as gram, second or meter. But also other non-standard units like parsecs.
Thus a kilogram is a thousand grams, a kilometer is a thousand meters and a kiloparsec is a thousand parsecs.
And a milligram is one thousandth of a gram, a millimeter is one thousandth of a meter and a millisecond is one thousandth of a second.
The full table of prefixes and of the initials used is as follows:
The standard SI unit prefixes, with symbols and factors:
yotta Y 10^24
zetta Z 10^21
exa E 10^18
peta P 10^15
tera T 10^12
giga G 10^9
mega M 10^6
kilo k 10^3
hecto h 10^2
deca da 10^1
(base unit)
deci d 10^-1
centi c 10^-2
milli m 10^-3
micro µ 10^-6
nano n 10^-9
pico p 10^-12
femto f 10^-15
atto a 10^-18
zepto z 10^-21
yocto y 10^-24
Many of these words will be unfamiliar but not all of them. Megabyte, gigabyte and increasingly terabyte will be familiar to computer users. And Nanotechnology, based on components that are the size of a human hair (a billionth of a meter thick) is increasingly a buzz word.

Mill means a thousand in Latin. Kilo means a thousand in Greek. So those who devised the metric system decided to use the Greek to show multiples, so a kilometer is one thousand meters. The Latin mill shows parts, so a millimeter in one one thousandth of a meter.
So a millimeter is a thousandth of a meter. Multiply that by one thousand meters, you come up with one million millimeters to a kilometer.

A kilometer is one thousand meters (big, like more than half a mile).
A millimeter is one one-thousandth of a meter (tiny, like 1/25th of an inch).
So a kilometer is bigger.

kilometer. It's 1,000,000 times bigger

Centimeters are bigger. It takes ten(10) millimeters to make up one(1) centimeter.
