Understanding Seconds and Weeks

Time is unique among measurement systems because it isn't decimal: 60 seconds make a minute, 60 minutes an hour, 24 hours a day, 7 days a week. This mixed-base system means converting between distant units (like seconds to days) requires chaining several factors, which is exactly what the table below does for you.

These conversions use standard definitions: 60 seconds per minute, 3,600 seconds per hour, 86,400 seconds per day. For months and years, average lengths are used (a year as 365.25 days) since calendar months vary in length.
