Time Converter

Our Time Converter is a versatile tool that helps you convert between different units of time: seconds, minutes, hours, days, weeks, months, and years. Whether you’re planning projects, calculating durations, or working with time intervals, this calculator makes time conversion simple and accurate.

Understanding Time Units

Base Units

Seconds (s)

The second is the SI base unit of time, defined by the duration of 9,192,631,770 periods of radiation from a cesium-133 atom.

Standard Time Units

Minutes (min)

1 minute = 60 seconds. Used for short durations and everyday timing.

Hours (h)

1 hour = 60 minutes = 3,600 seconds. Common for daily activities and scheduling.

Days (d)

1 day = 24 hours = 1,440 minutes = 86,400 seconds. Based on Earth’s rotation period.

Extended Time Units

Weeks (wk)

1 week = 7 days = 168 hours = 604,800 seconds. Common for medium-term planning.

Months (mo)

1 month ≈ 30.44 days = 730.5 hours = 2,629,800 seconds (average). Based on the calendar month.

Years (yr)

1 year = 365.25 days = 8,766 hours = 31,557,600 seconds (average, including leap years).

Conversion Formulas

Here are the formulas used for converting between different time units:

Base Unit (Seconds) Conversions

• 1 minute = 60 seconds
• 1 hour = 3,600 seconds

• 1 week = 604,800 seconds
• 1 month = 2,629,800 seconds (average)
• 1 year = 31,557,600 seconds (average)

Other Common Conversions

• 1 hour = 60 minutes
• 1 day = 24 hours
• 1 week = 7 days
• 1 month = 30.44 days (average)
• 1 year = 52.18 weeks = 12 months

Common Time References

Here are some common time measurements for reference:

• Typical work day: 8 hours
• Work week: 40 hours
• Lunar month: 29.53 days
• Calendar month: 28-31 days
• Standard year: 365 days
• Leap year: 366 days

How to Use the Calculator

1. Enter a value in any of the seven input fields (seconds, minutes, hours, days, weeks, months, or years)
2. The calculator will automatically convert and display the equivalent time in all other units
3. Use the Reset button to clear all fields and start a new conversion
4. Hover over the input fields for helpful tooltips

Applications

Time conversion is essential in many fields:

• Project Management: Duration calculations and scheduling
• Business: Work hours and billing time
• Science: Experimental timing and measurements
• Education: Course and study planning
• Travel: Time zone and journey duration calculations
• Sports: Performance timing and training schedules

Tips for Accurate Conversion

• Always use decimal points for precise measurements
• Consider whether to use average or exact month/year lengths
• Be aware of calendar variations (leap years, varying month lengths)
• Consider time zones when relevant
• Remember that months and years are not uniform units

Technical Notes

This calculator uses these standardized values:

• 1 day = 24 hours (exact)
• 1 week = 7 days (exact)
• 1 month = 30.44 days (average)
• 1 year = 365.25 days (average, accounting for leap years)

For extremely precise calculations or specific calendar dates, please use specialized date calculation tools.

Common Conversion Scenarios

• Converting work hours to days or weeks
• Calculating project durations
• Planning schedules across different time units
• Converting between different timing standards
• Estimating long-term durations
• Breaking down large time periods into smaller units

Time Standards

Different time standards exist for various purposes:

Civil Time

• Based on calendar days and clock hours
• Follows local time zones
• Accounts for daylight saving time

Universal Time (UT)

• Based on Earth’s rotation
• Used for astronomical observations
• Independent of time zones

Atomic Time

• Based on atomic oscillations
• Most precise time standard
• Used for scientific measurements
