Conversion Formula

Multiply the Second value by 1000 to get Millisecond.

The Measurement of Time

Unlike other measurements which rely on base-10 (metric) systems, time is measured using a sexagesimal (base-60) system inherited from the ancient Sumerians. This is why there are 60 seconds in a minute, and 60 minutes in an hour.

Global Standardization

Time is arguably the only measurement system that is entirely unified across the globe. Whether you are in the United States, Europe, or Asia, a second is fundamentally defined in the exact same way (based on the radiation periods of the caesium-133 atom).

Common Time Conversions

  • 1 Minute (min) = 60 Seconds (s)
  • 1 Hour (h) = 60 Minutes = 3,600 Seconds
  • 1 Day (d) = 24 Hours = 1,440 Minutes = 86,400 Seconds
  • 1 Week (wk) = 7 Days = 168 Hours
  • 1 Year (yr) = 365 Days (366 in leap years) = 8,760 Hours = 525,600 Minutes
