Oh, what a happy little question! There are 31,536,000,000,000 nanoseconds in a year. Isn't that just a wonderful thought? Just imagine all those tiny moments adding up to create a whole year of possibilities and joy.
1 second = 1000000000 nanoseconds
10 milliseconds = 10 million 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.
A nanosecond is 10-9 seconds. A millisecond is 10-3 seconds. There are 103 nanoseconds in a millisecond.
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.
9.5 years = 299,629,999,999,999,936 nanoseconds.
Six years = 1.89216e17 nanoseconds.
1 year = 3.1556926 × 1016 nanoseconds
3.16224 multiplied by 10 to the power of 16
1 year = 3.1556926 × 1016 nanoseconds
473,099,999,999,999,936 nanoseconds.
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
3.1536E+24 nanoseconds.
There are 86,400,000,000,000 nanoseconds in one day.
Yes, there are more nanoseconds in a second than the number of seconds in a year. A nanosecond is one billionth of a second, so there are 1,000,000,000 nanoseconds in one second. In a year, there are 31,536,000 seconds (in a non-leap year), which is significantly fewer than the number of nanoseconds in a single second.
1 second = 1000000000 nanoseconds
24 hours = 86,400,000,000,000 Nanoseconds
