Time Converter - Convert Time Units
Convert fixed durations between nanoseconds, microseconds, milliseconds, seconds, minutes, hours, days, weeks, and Year (365 days).
What Is a Time Converter?
This Time Converter converts a fixed duration from one time unit to another. It supports nanoseconds, microseconds, milliseconds, seconds, minutes, hours, days, weeks, and Year (365 days). It does not calculate calendar dates, leap years, or variable-length months.
How to Use This Converter
- Enter a non-negative time value — Changing the value does not update the displayed result yet.
- Select From — Choose the unit of the value you entered. The displayed result stays unchanged until you convert.
- Select To — Choose the unit you want to convert to. The displayed result still waits for Convert.
- Click Convert or press Enter — Calculate the result.
- Swap — Reverse the From and To units and convert using the current value.
- Copy Result — Copy the currently displayed conversion result.
- Reset — Restore the default 1 minute to hour conversion.
Time Unit Conversion Table
All factors below are the same values used by the converter. Year is a fixed 365-day duration, not a calendar year.
| Unit | Abbreviation | Conversion to Seconds |
|---|---|---|
| Nanosecond | ns | 0.000000001 s |
| Microsecond | µs | 0.000001 s |
| Millisecond | ms | 0.001 s |
| Second | s | 1 s |
| Minute | min | 60 s |
| Hour | h | 3,600 s |
| Day | day | 86,400 s |
| Week | week | 604,800 s |
| Year (365 days) | — | 31,536,000 s |
Practical Uses
- Software development: Convert milliseconds, microseconds, and nanoseconds used in timers and logs.
- Performance measurement: Compare benchmark durations across seconds and smaller units.
- Electronics: Convert pulse widths and delays.
- Science and laboratory work: Convert experimental time intervals.
- Scheduling: Convert minutes, hours, days, and weeks for everyday plans.
Common Time Conversions
| From | To | Conversion |
|---|---|---|
| 1 second | milliseconds | 1,000 ms |
| 1 minute | seconds | 60 s |
| 1 hour | minutes | 60 min |
| 1 day | hours | 24 h |
| 1 week | days | 7 days |
| 1 Year (365 days) | days | 365 days |
Fixed Durations vs Calendar Dates
This converter treats a day as exactly 24 hours and a year as exactly 365 days. Calendar months range from 28 to 31 days, and calendar years can be 365 or 366 days because of leap years. Month is not included here because it has no single fixed length. For calendar spans, use the Date Difference Calculator or the Age Calculator.
Frequently Asked Questions
What units does the Time Converter support?
It supports nanoseconds (ns), microseconds (µs), milliseconds (ms), seconds (s), minutes (min), hours (h), days, weeks, and Year (365 days).
How many seconds are in a minute?
There are exactly 60 seconds in 1 minute.
How many minutes are in an hour?
There are exactly 60 minutes in 1 hour.
How many hours are in a day?
This converter uses a 24-hour day, so 1 day = 24 hours = 86,400 seconds.
How many days are in a week?
There are exactly 7 days in 1 week.
How many milliseconds are in a second?
There are exactly 1,000 milliseconds in 1 second.
What is a microsecond?
A microsecond (µs) is one millionth of a second (0.000001 s), or 0.001 milliseconds.
What is a nanosecond?
A nanosecond (ns) is one billionth of a second (0.000000001 s). There are 1,000,000,000 nanoseconds in 1 second.
Does this converter support months and calendar years?
No. It does not include Month, and it does not calculate calendar years. Calendar months vary from 28 to 31 days, and calendar years can include a leap day. Use the Date Difference Calculator for calendar date spans.
Why is Year labeled "365 days"?
Year (365 days) is a fixed-duration convention equal to 365 × 24 hours (8,760 hours). A calendar year is not always 365 days. This option is for duration math, not for birthday or fiscal-year calendar math.
How precise are the results?
Conversions use exact SI second multiples and a 365-day year convention. Results are formatted to keep meaningful precision without padding extra zeros.
Is this time converter free?
Yes. It is free to use, with no registration or subscription. After the page loads, the converter also works offline.
