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.
There are 86,400,000,000,000 nanoseconds in one day.
60,000,000,000
There are 1,000,000,000 nanoseconds in one millisecond.
There are 3.1536 x 10^16 nanoseconds in a megayear, which is equivalent to one million years.
There are 1 billion nanoseconds in a second. This is because one second is equal to 1,000,000,000 nanoseconds when converted.
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.
1 second = 1000000000 nanoseconds
60,000,000,000
A nanosecond is 10-9 seconds. A millisecond is 10-3 seconds. There are 103 nanoseconds in a millisecond.
There are 1,000,000,000 nanoseconds in one millisecond.
There are 3.1536 x 10^16 nanoseconds in a megayear, which is equivalent to one million years.
473,099,999,999,999,936 nanoseconds.
There are one billion nanoseconds in a second, because it is 1/1,000,000,000 of a second
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.
3.1536E+24 nanoseconds.
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.
