20 kiloseconds = 20,000 seconds 60 seconds = 1 minute 60 minutes = 1 hour 330 min = 5.6 hours

In the SI system, the second is the base unit of time. We talk about atomic events that occur in picoseconds (10^-12s) or even in femtoseconds (10^-15s). But we do not talk about megaseconds or kiloseconds; the old standards of minutes, hours, and days prevail. How many minutes and hours are 20. kiloseconds?
