How many nanoseconds are in one hour? How do you write the following in scientific notation?

2,560,000m

3.6 * 10¹² nanoseconds

Explanation:

Hour is the unit of time. Seconds is the SI unit of time.

Hour and seconds are related as:

1 hour = 60 minutes

1 minute = 60 seconds

So,

1 hour = 60 * 60 seconds = 3600 seconds

Thus,

3600 seconds are in one hour

Also,

1 sec = 10⁹ nanoseconds

Thus,

3600 sec = 3600 * 10⁹ nanoseconds = 3.6 * 10¹² nanoseconds

Thus,

3.6 * 10¹² nanoseconds are in one hour.
