⏱️ Time Converter
Convert between 12 time units instantly
Pick a unit on each side of the converter above and type a value — the result appears as you type. Everything runs in your browser, so nothing is sent anywhere.
Time conversion covers everything from milliseconds used in computing and sport timing to years used in planning and finance. The category includes seconds, minutes, hours, days, weeks, months and years. Note that months and years use average values (a year is 365.25 days) because calendar months vary in length, so conversions involving them are approximations.
