How it works
Everything converts through seconds. Months and years vary in length, so averages are used: a year is 365.2425 days (the calendar average including leap years) and a month is a twelfth of that, about 30.44 days. For exact dates, use the date difference calculator.
Worked example
0.75 hours is 45 min (0.75 × 60).
