Understanding Days 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.

How accurate is this conversion?

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.

All conversion factors on ClearUnits are based on internationally recognised standards (the International System of Units, SI, and official definitions). Factors are reviewed for accuracy and the calculator uses full-precision values, rounding only the displayed result.
