What is a Time Converter?
A time converter is a tool that converts measurements of time duration from one unit to another. Whether you need to convert seconds to minutes, hours to days, or weeks to months, a time converter makes these calculations instant and accurate.
Time conversions are essential in many fields including scheduling, project planning, programming, science, and everyday life. Different contexts use different time units, making conversions a common necessity.
Our time converter supports 10 different units ranging from nanoseconds to years, handling everything from precise scientific measurements to long-term durations.
How it Works
Our time converter uses precise conversion factors to accurately transform values between different time units:
- Select Units: Choose the source unit and target unit from the dropdowns
- Enter Value: Input the time duration you want to convert
- Instant Results: The conversion is calculated automatically in real-time
- Swap Units: Click the swap button to reverse the conversion direction
The converter works by first converting to a base unit (seconds), then converting to the target unit. All conversions use standard time relationships (60 seconds = 1 minute, 60 minutes = 1 hour, etc.) for maximum accuracy.
Supported Units
Small Time Units
- Nanosecond (ns) - 0.000000001 seconds
- Microsecond (μs) - 0.000001 seconds
- Millisecond (ms) - 0.001 seconds
- Second (s) - Base unit
Common Time Units
- Minute (min) - 60 seconds
- Hour (h) - 3,600 seconds
- Day (d) - 86,400 seconds
- Week (wk) - 604,800 seconds
- Month (mo) - 2,592,000 seconds (30 days)
- Year (yr) - 31,536,000 seconds (365 days)
Common Use Cases
- Project Planning: Convert project durations, deadlines, and timelines between days, weeks, and months
- Programming: Convert time intervals, delays, and durations between milliseconds, seconds, and minutes for code
- Scheduling: Convert meeting durations, work hours, and time blocks between different units
- Science & Research: Convert precise time measurements between nanoseconds, microseconds, and milliseconds for experiments
- Time Tracking: Convert work hours, billable time, and time logs between hours, days, and weeks
- Education: Help students understand time relationships and practice conversions
- Long-term Planning: Convert durations between weeks, months, and years for planning and goal setting
Conversion Examples
Hours to Days
24 hours = 1 day
Example: 48 hours is 2 days. 72 hours is 3 days. A standard work week (40 hours) is approximately 1.67 days.
Weeks to Months
1 month (30 days) = 4.29 weeks
Example: 8 weeks is approximately 1.86 months. 12 weeks is approximately 2.79 months.
Seconds to Milliseconds
1 second = 1,000 milliseconds
Example: 0.5 seconds is 500 milliseconds. 2.5 seconds is 2,500 milliseconds. Common for programming delays and timing.
Days to Years
365 days = 1 year
Example: 730 days is 2 years. 1,095 days is 3 years. Useful for long-term planning and age calculations.
Frequently Asked Questions
Months have different numbers of days (28-31), and years can be 365 or 366 days (leap years). Our converter uses standard approximations: 1 month = 30 days and 1 year = 365 days for consistency. For precise date calculations, use a date calculator instead.
The converter automatically handles very small measurements (nanoseconds, microseconds) and will display them in scientific notation when appropriate. For example, converting nanoseconds to years might show a result like 3.17e-17.
