Reference: BIPM SI Brochure / 13th CGPM (1967)
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 Seconds to Milliseconds
Converting measurements between seconds and milliseconds follows a structured calculation process:
- Identify the quantity in seconds (s) that you wish to convert.
- Multiply the input by the conversion factor ratio
1 s = 1,000 ms. - The resulting value is the equivalent amount expressed in milliseconds (ms).

About the Units
Authoritative technical specifications and historical definitions for both units.
Second (s)
The second is the SI base unit of time. Officially defined by taking the fixed numerical value of the caesium frequency ΔνCs, the unperturbed ground-state hyperfine transition frequency of the caesium-133 atom, to be 9,192,631,770 Hz.
Millisecond (ms)
A metric unit equal to one-thousandth of a second (10^-3 s). Common in computing, electronics, and digital audio.
