Work it out by basic dimensional analysis!
One (average) year = 365.24 days
One day = 24 hours
One hour = 60 minutes
One minute = 60 seconds
so there are 365.24 * 24 * 60 * 60 seconds in a year.
One nanosecond is 10**9 seconds so multiply the above answer by 10**9 (or just shift the decimal point 9 places, it's loads easier)
BTW this same approach can be used to convert any comparable sets of units, e.g. miles per hour into metres per second, or even furlongs per fortnight if you really want to try.
By multiplication,
1 second = 1,000,000,000 nanoseconds (1 x 109 nanoseconds)
1 day = 86,400 seconds
1 year = 365.2422 days
so 1 year = 31,556,926,000,000,000 nanoseconds (3.1557 x 1016 nanoseconds)
(The Julian year consists of 31,557,600 seconds, based on 365.25 days.)
One second is equivalent to 1,000,000,000 nanoseconds.
That's one billion nanoseconds, 10E9, or 10**9 nanoseconds.
3.1556926 × 1016 31,556,926,000,000,000
1 Day = 86400000000000 Nanoseconds
Egvdf
1 second = 1000000000 nanoseconds
There are 109 nanoseconds in one second, and there are 60 x 109 nanoseconds in a minute. There are 60 x 60 x 109 nanoseconds in an hour, or 3.6 x 1012 nanoseconds in an hour.
There are one billion nanoseconds in a second, because it is 1/1,000,000,000 of a second
They are billionths of a second. 1 second = 1,000,000,000 nanoseconds
A nanosecond is one billionth of a second. One second is a billion nanoseconds. It is a VERY small slice of time.
according to dictionary.com it is one billionth of a second.
1,000,000,000 109 one billion
20 nanoseconds.
An hour is 3600 seconds, and a nanosecond is a billionth of a second, so an hour is 3,600,000,000,000 (three point six trillion) nanoseconds.
The Earth is 500 light-seconds from the Sun. One second is 10^9 nanoseconds.
One million - or 1 000 000.
A nanosecond is one billionth of a second. One second is a billion nanoseconds. It is a VERY small slice of time.
1 second = 1 billion nanoseconds 4 seconds = 4 billion nanoseconds = 4,000,000,000 = 4 x 109
There are 1,000,000,000 nanoseconds in a second. There are 1x60x60x24x365.25 or 31,557,600 seconds in a year. So nanoseconds in a second is over 60 times more
60,000,000,000
There are about 1,000,000,000 nano seconds in a second.
