What does SI prefix mean?

Answer 1

i know this is stupid, but that's why i remember it

tera giga mega kilo hecto deka deci centi milli micro nano pico femto atto Right?

k well i say

the giant mom killed her dumb doctor cause. and then i remember the alphabet hijkl M N o P... Micro Nano Pico. and then just idk the last two.. femto atto, you'll just actually have to remember those. hope that helped lol

Answer 2

SI prefixes define sub-units or multiples (of ten) and are added to SI units to make it easier to express large or small quantities. For example:

• You would probably say someone weighs 100 kg, not 100,000 grams.
• You would probably say you are going to walk 10 km, not 10,000 metres

The standard prefixes, their values and abbreviations:

Larger Units :

deca 1x101 da *

hecto 1x102 h *
kilo 1x103 k
mega 1x106 M
giga 1x109 G
tera 1x1012 T
peta 1x1015 P
exa 1x1018 E
zetta 1x1021 Z
yotta 1x1024 Y

Smaller Units :

deci 1x10-1 d *
centi 1x10-2 c
milli 1x10-3 m
micro 1x10-6 µ * *
nano 1x10-9 n
pico 1x10-12 p
femto 1x10-15 f
atto 1x10-18 a
zepto 1x10-21 z
yocto 1x10-24 y

* Also defined but not widely used for all units

** While micro is officially abbreviated μ (the greek letter mu), it is common practice to substitute the lower-case u in its place for keyboard convenience.


The following metric prefixes were generally used as part of the metric system prior to standardization through SI.

myria 1x104 ma or my
myrio 1x10-4 mo

Answer 3

SI prefixes precede a unit of measure to indicate decimal multiples or dividions. This reduces the number of zeros needed to express large or small quantities. One gigabyte is easier to read, write and say than 1000000000 bytes and one microsecond is simpler than .000001 second. For measuring length (meter), volume (liter), or mass (gram) prefixes are all the same. SI prefixes stand for: 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) = Ten

hecto (h) = One 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 4

SI prefix refers to a set of prefixes used in the International System of Units to denote decimal multiples and submultiples of units. These prefixes are added to the base unit to indicate a specific magnitude of measurement, making it easier to work with very large or very small values. Examples of SI prefixes include kilo- (10^3), mega- (10^6), and milli- (10^-3).

Answer 5

Answer 6

Its french. Système International [d'Unités]

International system

Answer 7

Si (with a small 'i') would be the element silicon. SI (with a capital 'I') would not be an element, it would be a compound. It's excessively fussy, I know.

Answer 8

It means "one thousand".
