Question

How many nanoseconds in 1 year?

Answer 1

\[1 s=10^{9}ns\]
\[1 year=365days=365*24hours=365*24*60 \min=365*24*60*60s\]
365*24*60*60 * 10^9 = 31536 * 10^12 ns

Answer 2

one year=365*24*60*60=\[3.1536\times10^{7}\]s
one second =\[10^{9}\] nanosecond
one year=\[3.1536\times10^{7}\times10^{9}\]ns
one year=\[3.1536\times10^{16}\]ns
