There are 86,400 seconds in a day, from 24 hours times 60 minutes times 60 seconds. A week is 604,800 seconds. These are exact for a standard day and ignore leap seconds.
Multiply hours by 60. For example, 2.5 hours is 150 minutes. Decimal hours are not hours and minutes, so 2.5 hours is 2 hours 30 minutes. Enter the decimal value in the tool and it converts it directly.
Months and years vary in real life, so the tool uses averages. A year is 365.2425 days (31,556,952 seconds), the Gregorian average, and a month is one twelfth of that, about 30.437 days (2,629,746 seconds). For a specific calendar span, count actual days.
Milliseconds, seconds, minutes, hours, days, weeks, months, years and decades. The tool converts through seconds, so 1 hour is 3,600 seconds, 1 week is 604,800 seconds and 1 decade is 315,569,520 seconds using the average year.
A common year has 365 days and a leap year has 366. The Gregorian calendar average is 365.2425 days, which this converter uses. That means 1 year is about 52.18 weeks rather than exactly 52.
Keep the whole number as hours and multiply the decimal part by 60 for minutes. For example, 1.75 hours is 1 hour and 0.75 x 60 = 45 minutes. This matters for timesheets and payroll, where 7.5 hours means 7 hours 30 minutes.
