Basic Time Unit Conversion

To convert time units, you must remember these key relationships:

• 1 minute = 60 seconds
• 1 hour = 60 minutes
• 1 day = 24 hours
• 1 week = 7 days
• 1 year ≈ 365 days (or 366 in a leap year)

For scientific calculations:

• 1 second = 1,000 milliseconds
• 1 millisecond = 1,000 microseconds
• 1 microsecond = 1,000 nanoseconds
• 1 nanosecond = 1,000 picoseconds

For longer time spans (average values used in calculations):

• 1 year ≈ 12 months
• 1 decade = 10 years
• 1 century = 100 years
