SI prefixes, also known as a metric prefixes, are names or associated symbols that precedes a unit of measure or its symbol to form decimal multiples or submultiples. SI prefixes are used to reduce the quantity of zeroes in numerical equivalencies. For measuring length (meter), volume (liter), or mass (gram) prefixes are all the same. Femto (f) 10-15 One Quadrillionth

Pico (p) 10-12 One Trillionth

Nano (n) 10-9 One Billionth

Micro (µ) 10-6 One Millionth (greek letter 'mu')

Milli (m) 10-3 One Thousandth

Centi (c) 0.01 One Hundredth

Deci (d) 0.1 One Tenth

one = initial value

deka (dk) = 10 Ten

hecto (h) = 100 Hundred

Kilo (k) 103 One Thousand

Mega (M) 106 One Million

Giga (G) 109 One Billion

Tera (T) 1012 One Trillion

Peta (P) 1015 One Quadrillion

The scientific prefixes are:

pico, nano, micro, milli, centi, deci, deca, hecto, kilo, mega, giga, terra

all in order from 10 to the -12 power to the 10 to the 12 power

pico=10 to the -12, nano=10 to the -9, micro=10 to the -6, milli=10 to the -3, centi=10 to the -2, deci=10 to the -1, deca=10 to the 1, hecto=10 to the 2, kilo=10 to the 3, mega=10 to the 6, giga=10 to the 9, terra=10 to the 12

Hope that helps!

SI units have the advantage that their multiples and sub-multiples can be expressed in terms of prefixes.prefixes are the word or letters added before SI units such as lilo,mega,giga,and milli>>>>>>>>>>>>>>........<<<<<<<<<<<<

Unlike ionic compounds, which are known to transfer electrons in specific numbers from metal to nonmetal, covalent compounds can often share electrons in many different arrangements.

For example, nitrogen and oxygen can share electrons to form many different compounds, requiring prefixes to distinguish them:

N2O

NO

NO2

...etc...
