Convert seconds to nanoseconds on a calculator?

  1. Sep 22, 2004 #1
    hye this might b a stupid question to ask here but how would one convert seconds to nanoseconds on a calculator? a program for TI format would answer my question (if u know how) or just an equasion

    Thanks

    Multiply by 1e9

    nano <=> 10E-9

    Dividing by 1 billion is the same as dividing by 109.

    Perhaps kawikdx225 mean "multiply by 10-9".

    No, I meant multiply by 1e9 ie 1000000000

    1 second = 1000000000 nanoseconds

    Let's just clarify this.

    [tex]1\ ns= 10^{-9}\ s = \frac{1\ s}{10^9}[/tex]

    Technically speaking, of course, when we "convert units" we really only multiply the measured quantity by 1... otherwise you change the quantity.
    Depending on the conversion you desire, write 1 using
    [tex] 1 =\frac{10^{-9}\ s}{1\ ns} =\frac{1\ ns}{10^{-9}\ s} [/tex]


    [tex] 1.23\ s = 1.23\ s (1) = 1.23\ s \left( \frac{1\ ns}{10^{-9}\ s} \right)
    =1.23\ ( 10^{9}\ ns) = 1.23 \times 10^{9}\ ns[/tex]

    Sorry about that - I typed the wrong thing and had to run before proofing. Thanks to all for catching my error.

    Wow, look guys this is simple.

    1nS = 1e-9 seconds
    1 second = 1e9 nanoseconds
    The original poster wants to convert seconds to nanoseconds so we multiply by 1 billion.

    Lets use small numbers. :smile:
    lets convert 1 second to nanoseconds. 1 x 1e9 = 1 billion. 1 second = 1 billion nanoseconds. See it's simple. :biggrin:

    milli = 10-3
    micro = 10-6
    nano = 10-9
    pico = 10-12
    femto = 10-15
    atto = 10-18

    Just in case you need to do more converting. :smile:

    Not particularly relevant to the thread but am I correct in thinking that in America 109 is 1 billion?
     
  15. Sep 23, 2004 #14
    yeah, but one person sed 1/1E9 and one person sed 1X1E9 and at the time i had too much work to just figure it out with common sence so yeah

    Yes, 1 billion is 109 almost every in the world, including where I am from, Asia. However, 10-9 is called nano-.

    Just for fun, some additional information for scientific notation:
    kilo = 103
    mega = 106
    giga = 109
    tera = 1012
    peta = 1015
    exa = 1018

    Actually by the original definition billion is 1012. (And still the definition in England)

    Billion quite simply means bi-million, as in a million millions.

    Trillion means tri-million, as in a million million millions (1018)

    Quadrillion... etc..
