Understanding Time Units
Common time units and relationships:
- Seconds (s): SI base unit of time. 1 second = 1,000 milliseconds = 1,000,000 microseconds = 1,000,000,000 nanoseconds.
- Minutes: 1 minute = 60 seconds. Used for short durations and timekeeping.
- Hours: 1 hour = 60 minutes = 3,600 seconds. Standard unit for work schedules and daily activities.
- Days: 1 day = 24 hours = 1,440 minutes = 86,400 seconds. Based on Earth's rotation.
- Weeks: 1 week = 7 days = 168 hours. Common for scheduling and planning.
- Months: Average month = 30.44 days (365.25 ÷ 12). Calendar months vary (28-31 days).
- Years: 1 year = 365.25 days (accounting for leap years) = 8,766 hours = 525,960 minutes.

Time Measurement Standards
Important time measurement concepts:
- SI Second: Defined as 9,192,631,770 periods of radiation from cesium-133 atom transitions.
- Leap Years: Every 4 years (except century years not divisible by 400) adds an extra day to February.
- Average Year: 365.25 days accounts for leap years over long periods.
- Month Variations: Calendar months range from 28-31 days. Average = 30.44 days for consistent calculations.
- Time Zones: Earth is divided into 24 time zones, each approximately 15° of longitude wide.
Note: All conversions use standard conversion factors. The second is the SI base unit of time. Months are calculated using the average month length (30.44 days) for consistency, though calendar months vary. Years use 365.25 days to account for leap years. For precise calendar calculations, consider the specific month and year.
