2 seconds = microseconds

2 seconds = milliseconds

3000000000 nanoseconds = seconds

1 microsecond = 1000 nanoseconds

1 millisecond = 1000 microseconds

1 second = 1000 milliseconds

5. Time unit conversion.

5 quarters = months

5 decades = quarters

3 decades = years

4 millenniums = decades

2 millenniums = centuries

72000 months = millenniums
