Time Unit Converter
Convert a value between any two time units — seconds, minutes, hours, days, weeks, months and years. Enter an amount, pick the unit it is in, and read every equivalent at once.
How the time unit converter works
Every unit is converted through a common base of seconds. A minute is 60 seconds, an hour 3,600, a day 86,400, a week 604,800. Months and years use the average lengths of 30.44 and 365.2425 days so long spans stay accurate.
Type a number, choose its unit, and the converter lists the same amount in all the other units instantly.
