About time units
The second is the SI unit of time. A minute is 60 seconds, an hour 3,600 seconds and a day 86,400 seconds. Months and years vary in length, so converters use the average Gregorian values: a year of 365.2425 days and a month of 30.436875 days.
Where time conversions are used
Time conversions are used for timesheets and payroll, cooking and workout timers, project planning, travel times and turning a decimal number of hours into hours and minutes.
Conversion factors use exact international definitions where they exist (for example 1 inch = 2.54 cm and 1 lb = 0.45359237 kg). Results are rounded for display only.
