Seconds to Milliseconds Converter (s to ms)

Seconds

The second is the SI base unit of time, defined since 1967 as the duration of exactly 9,192,631,770 cycles of radiation from the caesium-133 atom. Atomic clocks based on this definition lose less than one second in 300 million years. The second underpins all timekeeping in modern civilisation — from GPS satellite synchronisation to internet protocols and financial transaction timestamps.

Milliseconds

The millisecond is a unit of time equal to one thousandth of a second (10⁻³ s) and represents the timescale of human physiological responses and digital audio. The human minimum reaction time to a visual stimulus is approximately 150–200 milliseconds. Network latency in internet communications is measured in milliseconds, where values below 20 ms are considered excellent for real-time applications.
