Time Unit Converter
Pick any two time units and type in either box. Minutes, hours, days and weeks are fixed multiples of the second, so these conversions are exact.
2 h = 120 min
Why months and years are not listed
A minute is always 60 seconds, an hour 60 minutes, a day 24 hours and a week 7 days (ignoring the rare leap second and daylight-saving clock changes). Months are 28 to 31 days long and years 365 or 366 days, so converting “months to days” has no single answer. For calendar spans use the days between dates or date difference calculator.
Decimal hours vs hours and minutes
0.5 h is 30 minutes, not 50. To turn decimal hours into minutes, multiply the decimal part by 60: 3.2 h = 3 h 12 min.
