1.5 days = 1.29600 × 1014 nanoseconds.
Well, an eon is a really, really long time, like the blink of an eye for the universe. And a nanosecond is a tiny, tiny fraction of a second, like a little whisper in the wind. So, there are so many nanoseconds in an eon that it's like trying to count all the happy little trees in a forest - you just have to appreciate the beauty of it all instead.
None. It's a trick question. Light travels in firsts.
I could write 1 femtosecond as "1 femtosecond" : not a zero in sight. or as 0.000001 nanoseconds (6 zeros) or .000001 nanoseconds (5 zeros) 1 fs = 10-15 seconds so there are 14 0s between the decimal point and the 1.
How many hours does it take to get to 4.5 billion km
The Earth is 500 light-seconds from the Sun. One second is 10^9 nanoseconds.
473,099,999,999,999,936 nanoseconds.
3.1536E+24 nanoseconds.
There are 86,400,000,000,000 nanoseconds in one day.
There are one billion nanoseconds in one second.
1 microsecond = 1,000 nanoseconds.
Six years = 1.89216e17 nanoseconds.
20,000,000,000 nanoseconds = ~0.333 minutes.
9.5 years = 299,629,999,999,999,936 nanoseconds.
24 hours = 86,400,000,000,000 Nanoseconds
1.5 days = 1.29600 × 1014 nanoseconds.
5 milliseconds = 5 million nanoseconds.
