Time Measurement Standards & Base Units
The SI base unit of time is the second (s), defined by the resonance frequency of the caesium-133 atom.
Larger time intervals follow the historical sexagesimal (base-60) system: 1 minute = 60 seconds, 1 hour = 60 minutes (3,600 seconds), and 1 standard day = 24 hours (86,400 seconds). Conversions between standard time units are exact whole integers.
How to Convert Weeks to Days
Converting measurements between weeks and days follows a structured calculation process:
- Identify the quantity in weeks (wk) that you wish to convert.
- Multiply the input by the conversion factor ratio
1 wk = 7 d. - The resulting value is the equivalent amount expressed in days (d).
