Frequently Asked Questions
How do I convert minutes to hours?
To convert minutes to hours, divide by 60. For example, 90 minutes = 1.5 hours (90 ÷ 60). Our converter handles this automatically - just enter the minutes and select hours as the target unit. The formula is: hours = minutes ÷ 60.
How many seconds are in a day?
There are 86,400 seconds in a day. This is calculated as: 24 hours × 60 minutes × 60 seconds = 86,400. Our converter shows this instantly when you enter 1 day and convert to seconds.
What is a fortnight?
A fortnight is a unit of time equal to 14 days (two weeks). The term comes from the Old English "fēowertȳne niht" meaning "fourteen nights." It's commonly used in British English and some other Commonwealth countries. 1 fortnight = 1,209,600 seconds.
How are months and years calculated?
For simplicity and consistency, our converter uses: 1 month = 30 days (average month length) and 1 year = 365 days (non-leap year). For precise calendar calculations involving specific dates, consider using a date calculator instead.
How do I convert between hours, minutes, and seconds?
These conversions are straightforward: 1 hour = 60 minutes = 3,600 seconds. To go from larger to smaller units, multiply (hours × 60 = minutes). To go from smaller to larger, divide (seconds ÷ 60 = minutes). Our human-readable display shows combined formats like "2h 30m 15s" for easy understanding.
