Time Converter
Convert between milliseconds, seconds, minutes, hours, days, weeks, and years.
Time Unit Converter
Enter a duration and choose the time units to convert between. This tool converts durations, not time zones.
Months and years use average calendar values.

Time Duration vs Clock Time
Duration conversion
Duration is an amount of elapsed time, such as 90 minutes, 2 hours, or 7 days. This converter changes duration units.
Clock and time zone conversion
Clock time is a time of day, such as 10:00 PM. Time zone conversion changes the displayed time between locations.
Crossing dates
Adding 3 hours to 10 PM may cross a date boundary, but this converter only handles unit conversion.
Calendar tools
For exact calendar differences, use the Date Calculator or Date Difference Calculator.
Metric-Style Time Scaling
Sub-second units
Milliseconds, microseconds, and nanoseconds scale by powers of 1,000.
Conventional units
Seconds, minutes, hours, days, and weeks use traditional relationships instead of a pure decimal system.
Calendar units
Months and years depend on calendars, leap years, and month length.

Practical Use Cases
Formula Explanation
Converted Value = Input Value × Conversion Factor
minutes = seconds ÷ 60
hours = minutes ÷ 60
days = hours ÷ 24
weeks = days ÷ 7
days ≈ years × 365.2425
days ≈ months × 30.436875
The converter changes the input value into seconds, then converts seconds into the selected target unit. Rounded results are shown for readability. Month and year conversions use average Gregorian values, so exact calendar results may differ when specific dates are involved.
