Quick Reference

1 minute= 60 seconds
1 hour= 60 minutes = 3,600 seconds
1 day= 24 hours = 86,400 seconds
1 week= 7 days = 168 hours
1 year= 365 days = 8,760 hours

Understanding Time Units

•
Second (s): SI base unit of time, defined by cesium atomic clock
•
Standard Year: 365 days (8,760 hours), leap year has 366 days
•
Month: Varies from 28-31 days; calculator uses 30 days average
•
Fortnight: 14 days, still used in UK and Australia
•
Millisecond: 1/1000 second, human reaction time ~200-300 ms
•
Nanosecond: 1 billionth of a second, light travels ~30 cm in 1 ns
