Units of measurements
Metric prefixes:
There are 7 Base units that are the most used that were decided by the international system of Units:
Meter (M) for Length
Kilogram(kg) for Mass
Second (S or Sec) for Time
Kelvin (K) for Temperature
Mole (Mol) for the amount of a Substance
Ampere (A) for electric current
Candela (Cd) for Luminous Intensity
The reasons that they decided to use these measurements are because its easier to calculate with this units, they are all based on 10, and they are understood around the world.
SI prefixes: These are used to go before the base unit. They can be either smaller or larger than the base. The prefixes are:
giga (G) 1x10^9
Mega (M) 1x10^6
Kilo (k) 1x10^3
Hecto (h) 1x10^2
Deca (da) 1x10^1
Deci (d) 1x10^-1
centi (c) 1x10^-2
mili (m) 1x10^-3
Micro 1x10^-6
nano (n) 1x10^-9
