What are the metric prefix's and their multipliers of the base unit from kilo to milli?

Answer 1

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

Answer 2

In modern usage the prefixes that tend to be used are those that go up or down by order of 1 000, that is billionths, millionths, thousandths, base unit, thousands, millions, billions (nano-, micro-, milli-, base, kilo-, mega-, giga-). So milli and kilo are the first prefixes used.

Officially there are prefixes for hundredths, tenths, tens, and hundreds, but these are only used very rarely.

Hundredths are centi-, this is only used for metres, in all technical measurements millimetres are preferred.

Tenths are deci- this is only really used in the non-SI decibel.

Tens are deca- I know of no situation where this is used.

Hundreds are hecto-, this is manily used for the non-SI hectare, in SI area is measured in square metres.

The one exception is the kilogram. Kilogram is the base unit of mass. the prefixes are used one step out for simplicity, otherwise a gram is one thousand of the base unit so would be a millikilogram, a tonne is one thousand base units so would be a kilokilogram (a tonne is really a megagram).
