SwitchExplanation
Formula: Seconds = Hours × 3,600. Why: both units are short fixed time scales built directly from seconds and minutes, so the route follows exact integer relationships through one second reference.
Hours (h): a civil time unit equal to exactly 3,600 seconds, widely used for work, travel, and scheduling.
Seconds (s): the SI base unit of time, used as the common reference for fixed civil-time conversions.
This route is useful when restating short fixed durations between seconds, minutes, and hours for scheduling, logging, and time-tracking work.
This conversion is purely multiplicative because both units reduce through seconds using fixed civil time definitions with no offset.
