The prefix meaning 10 in the metric system?

Answer 1

Bin-, standing for 2.

Tri-, standing for 3.

Quadr-, standing for 4. Hence the word "Square" = (S)quadr-

Quin(t)-, standing for 5.

Hex-, standing for 6.

Sept-, standing for 7.

Oct(a)-, standing for 8.

Nona-, standing for 9.

Deca-, standing for 10.

Dozen, standing for 12. ("Thousands" stands for: Dozens, because many dozens = many thousands, in the production line).

Hexadeci-, standing for 16.

In Numericals, and in Measurements:

Deca- / Deka-, standing for 10 (times 10)

Hecto-, standing for 100 (times 100).

Kilo-, standing for 1000 (times 1000).

[Myriad-, standing for 10000.]

Mega-, standing for 1000000 (= 10^6).

Giga-, standing for 1000000000 (= 10^9).

Tera-, standing for 1000000000000 (= 10^12).

Peta-, standing for 1000000000000000 (= 10^15).

The whole sequence is:

Kilo, mega, giga, tera, peta, exa, zetta, yotta, xona, weka, vunda, uda, treda, sorta, rinta, quexa, pepta, ocha, nena, minga, luma.

where every succedent (next) member of it equals 1000 times the precedent (e.g. Exa = Peta times 1000, Yotta = Exa times 1000000).

Actually, "treda" suggests 13, "quexa" suggests 16.

(That is: Treda- = (10^3)^13 = 10^39. Quexa- = (10^3)^16 = 10^48.)

For fractions, the sequence is:

deci-, standing for 1/10.

centi-, standing for 1/100.

milli-, standing for 1/1000.

micro-, standing for 1/1000000 (10^-6)

nano-, standing for 1/1000000000 (10^-9)

pico-, standing for 1/1000000000000 (10^-12)

The whole sequence is:

milli, micro, nano, pico, femto, atto, zepto, yocto, Y, Z, E, P, T, G, M, k, h, da, d, c, m, Á, ...
