Multiply the time in seconds by 1 billion (1,000,000,000 or 10**9) to get the same time in nanoseconds.
Multiply by 1000000000 ns/s.
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 a second. Therefore 1.5/1000000000 is 0.0000000015 seconds
A nanosecond is one billionth of a second, or 1/1,000,000,000 seconds. Therefore, 9 nanoseconds is nine billionths of a second, or 9/1,000,000,000 seconds, or 9.0 x 10-9 seconds.
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.
Multiply by 1000000000 ns/s.
4.29 seconds = 4.29 billion nanoseconds.
4.1nanoseconds=0.000000041 seconds 1 Second = 1000000000 Nanoseconds
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
216 seconds is 216x109 nanoseconds. (890/(216x109))*100 is 4.12037x10-7%
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.
1 minute = 60 seconds 5 minutes = 300 seconds = 300 billion nanoseconds
A nanosecond is 10-9 seconds. A millisecond is 10-3 seconds. There are 103 nanoseconds in a millisecond.
Nano is the prefix of 10^(-9) or 0.00000001. So 28 nanoseconds is 2.8*10^(-8) seconds
There are 1,000,000,000 nanoseconds in a second. Therefore 1.5/1000000000 is 0.0000000015 seconds
To convert from nanoseconds to minutes, divide by 60 million.
