Common Time Conversions

Here are some of the most frequently used time conversions:

1 Minute = 60 Seconds
1 Hour = 60 Minutes = 3,600 Seconds
1 Day = 24 Hours = 1,440 Minutes
1 Week = 7 Days = 168 Hours
1 Month (avg) = 30.44 Days = 730.56 Hours
1 Year = 365 Days = 8,760 Hours (8,784 in leap year)
Quick Tip: To convert minutes to hours, divide by 60. To convert hours to days, divide by 24. For days to weeks, divide by 7.
