Convert between time units and see multi-format breakdowns
This time converter supports nine units: seconds, minutes, hours, days, weeks, months (30.44 days), years (365.25 days), decades, and centuries. It converts between all units and displays a multi-format breakdown showing the same duration expressed in different units (e.g., "2 days = 48 hours = 2880 minutes = 172800 seconds").
Select the time unit you are converting from, enter the value, and click "Convert". The results include a multi-format breakdown and a complete conversion table for all nine units. The default value of 2 days shows a clear example of how the same duration expands across time scales.
The average month length is 30.44 days, calculated as 365.25 days per year divided by 12 months. This accounts for both leap years (366 days every 4 years) and the varying lengths of calendar months. Using 30.44 days provides a consistent average for conversion purposes.
The Earth's orbit around the sun takes approximately 365.2425 days (a tropical year). Using 365.25 days accounts for leap years — an extra day every four years. For even greater precision, many calculations use 365.2425 days (accounting for century leap rules), but 365.25 is standard for general conversions.
