Metric prefix

Presentation of the different tipes of metric prefix. From yotta to yocto.

1. METRIC PREFIX

2. Yotta Yotta is the largest unit prefix in the International System of Units (SI), denoting a factor of 1024. It has the unit symbol Y. The prefix name is derived from the Greek οκτώ ( októ ), meaning eight, because it is equal to 10008. The total power output of the  Sun  is approximately 385 YW.

3. Zetta Zetta  is a unit  prefix in the metric system  denoting a factor of 10 21 . The prefix was added to the International System of Units (SI ) in 1991 and has the symbol  Z . Zetta is evocative of the Latin numeral  septem , meaning  seven . Therefore it was used to denote the seventh power of 1000. The mass of Earth's atmosphere is approximately 5 zettagrams ( Zg ).

4. Exa Exa  is a unit prefix in the metric system denoting 10 18 . It was added to the International System of Units (SI) in 1975, and has the unit symbol E. Exa  comes from the Greek ἕξ, used as a prefix ἑξά-, meaning  six , because it is equal to 1000 6 . 0.43 Es ≈ the approximate age of the Universe.

5. Peta Peta  is a unit prefix  in the metric system denoting multiplication by 10 15 . It was adopted in the International System of Units in 1975 ,  and has the symbol  P . Peta  is derived from the Greek π έντε , meaning "five". It denotes the fifth power of 1000 (1000 5 ). The distance light travels in a year is 10 Pm.

6. Tera Tera  is a unit prefix in the metric system denoting multiplication by 10 12 . It has the symbol  T . The prefix tera was confirmed for use in the SI in 1960. Tera  is derived from Greek word τέρας  teras , meaning “monster ”. The orbit of Ceres is 1Tm.

7. Giga Giga is a unit prefix in the metric system denoting a factor of a billion, 10 9 . It has the symbol  G . Giga  is derived from the Greek word γίγας, meaning "giant ". The orbit of the moon is measured in 1Gm.

8. Mega Mega  is a unit  prefix M  in the metric system denoting a factor of one million, 10 6 . It was confirmed for use in the International System of Units (SI) in 1960 . Mega  comes from the Greek μέγας  megas , meaning "great ". The state of Florida is 1Mm.

9. Kilo Kilo  is a unit prefix in the metric system denoting multiplication by one thousand .  It has been used in the International System of Units where it has the unit symbol  k , in lower case . The prefix  kilo  is derived from the Greek word  χίλιοι, meaning "thousand ". The Grand Coulee Dam is 1km.

10. Hecto Hecto  or  hecta  is a unit prefix in the metric system denoting a factor of one hundred . Comes from the Greek ἑκατόν  hekaton , meaning  hundred . Its unit symbol in the International System of Units (SI) is the lower case letter  h . The Court House is 1hm.

11. Deca Deca -  or  deka -  (symbol  da ) is a prefix in the metric system, also a numerical prefix, denoting a factor of ten . The term is derived from the Greek  δέκ α  meaning "ten". Its symbol is the only SI prefix that uses more than one character . The Oak tree is 1dam.

12. Deci Deci  (symbol  d ) is a prefix in the metric system denoting a factor of one tenth . The prefix comes from the Latin  decimus , meaning  tenth .  Its most frequent use is in the non-SI  unit. The maple leaf can be measured in 1dm.

13. Centi Centi  (symbol  c ) is a prefix in the metric system denoting a factor of one hundredth. The prefix comes from the Latin  centum , meaning  hundred .   It is mainly used with the meter to express lengths in  centimeters. A honeybee is about 1.3 centimeters in length.

14. Milli Milli  (symbol  m ) is a prefix in the metric system denoting a factor of one thousandth (10 -3 ).   The prefix comes from the Latin  mille , meaning  one thousand. A snow crystal is about 1 millimeter in diameter .

15. Micro Micro  (symbol  µ ) is a prefix in the metric system denoting a factor of 10 −6   . The prefix comes from the Greek  μικρός, meaning "small ". It is the only SI prefix which uses a character not from the Latin alphabet . The size of the influenza virus is about 0.8 to 1.2.

16. Nano Nano -  (symbol  n ) is an SI prefix meaning one billionth.   Used primarily with the metric system, this prefix denotes a factor of 10 − 9 . It is frequently encountered in science and electronics for prefixing units of time and length . One nanometer is about the length that a fingernail grows in one second.

17. Pico Pico-  (symbol  p ) is a prefix in the metric system denoting one trillionth, a factor of 10 −12   . Derived from the Spanish  pico , meaning  peak ,  beak ,  bit . The radius of atoms range from ~25 picometers (hydrogen ).

18. Femto Femto -  (symbol  f ) is a prefix in the metric system denoting a factor of 10 −15   .   It was added in 1964 to the SI . It is derived from the Danish word  femten , meaning "fifteen ". A proton  as a diameter of about 1.6 to 1.7 femtometres .

19. Atto Atto -  (symbol  a ) is a prefix in the metric system denoting a factor of 10 −18   . It is derived from the Danish word  atten , meaning "eighteen ". Weight of the HIV-1 Virus is about 1 ag.

20. Zepto Zepto -  (symbol  z ) is a prefix in the metric system denoting a factor of 10 −21   .   It comes from the Latin  septem , meaning "seven", since it is equal to 1000 −7 . The human insulin molecule is roughly 10 zeptograms .

21. Yocto Yocto  (symbol  y ) is a prefix in the metric system denoting a factor of 10 −24   .  It comes from the Latin/Greek  octo  ( οκτώ ), meaning "eight", because it is equal to 1000 −8 . Rest mass of proton:1.6726 yg
