A picometre is a thousandth of a nanometre.
kilo = 1000deci = 1/10 centi = 1/100 milli = 1/1000 micro = 1/1000000 nano = 1/1000000000.
Mathematicians, engineers and scientists avoid the words billion and billionth because they have different meanings in different countries. e.g. one billion (US) 109. one billion (UK) 1012. So, mathematicians use exponents as shown above. Engineers and scientists mostly use SI multipliers. 106 = Mega, 109 = Giga, 1012 = Tera 10-6 = micro, 10-9 = nano, 10-12 = pico. If you are American, a billionth is 10-9 . If you are a Brit it is 10-12.

No - at least not in the English language. We have zero (starts with z) one (starts with o) two (starts with t) three (starts with t) four (starts with f) five (starts with f) six (starts with s) seven (starts with s) eight (starts with e) nine (starts with n) ten (starts with t) eleven (starts with e) twelve (starts with t) thirteen (starts with t) fourteen (starts with f) fifteen (starts with f) sixteen (starts with s) seventeen (starts with s) eighteen (starts with e) nineteen (starts with n) twenty (starts with t) thirty (starts with t) forty (starts with f) fifty (starts with f) sixty (starts with s) seventy (starts with s) eighty (starts with e) ninety (starts with n) from there on up, all numbers start with one of these, for example: 35,500,400,122 Thirty five billion five hundred million, four hundred thousand one hundred twenty-two (starts with T) We do have some number related words that we don't actually start the names of numbers with: Hundred Thousand Million Billion Trillion Quadrillion Quintillion Sextillion Septillion Octillion Nonillion Decillion Undecillion Duodecillion Tredecillion Quatrodecillion Virgintillion ... and so forth continuing to use the same types of prefixes with u (un), b(bi) d(duo,dec), t(tri), q(quad, quint), s(sex, sept), o(oct), n(non), c(cent), m(mili), None of them start with "J". The extremely large numbers Googol and Googleplex both start with G. The metric prefixes include kilo mega giga tera peta exa zeta yotta (none of which start with J) and fractional prefixes of deci centi milli micro nano pico femto atto zepto yocto (still nothing starting with J) Informally 10 to the 27th power is called "hella" - as sort of a nerd joke - but still no "J" number.
The SI nano- prefix means x 10-9
nano
nano-
'Nano' is not a noun; 'nano' is not even a word, it is a prefix meaning 'one billionth' or used informally as an extremely small part of a whole. Some words with the prefix nano- are nanosecond, nanotechnology, or nanoscale.
There would be 4,000,000,000 nanoseconds in 4 seconds. This can be figured out because a nano second is . 0000000001 a second, meaning that there are 1,000,000,000 nanoseconds in one second.
nano-
Nano.
micro- nano-
Nano- means million.
The prefix "nano" = 1/1,000,000,000 indicates 10^-9 or a billionth.
The prefix "nano" means 10 to the power -9, in other words, a factor of 0.000 000 001.
