Are you able to calculate that how many nanoseconds are there in a second?

Easy Fix with Online Calculator

In one second there are 1,000,000,000 nanoseconds.

Nowadays people use seconds, minutes, hours to measure time in a day, which makes everything easier. Also, with International System of Units, millisecond, microsecond, nanosecond and picosecond are members of this time unit family. So how many nano seconds are in a second? How many nanoseconds are in one second?

There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and a nanosecond is one billionth of a second (10 or /1,000,000,000 s). So let’s do it step by step: 1 nanosecond is equal to how many seconds? And we’ll move onto more exercise with: how many seconds in 1.39 nanoseconds?

So,
. 1 second = 1,000,000,000 nanoseconds
. 1 s = 1000 ns
1 second = 1000 nanoseconds (PS: nanosecond= ns, second= s)

More exercise: How many nanoseconds are in 1.39 seconds? 
. 1 s = 1,000,000,000 ns
. 1.39 s = 1,000,000,000 x 1.39 = 1,390,000,000 nanoseconds
