About seconds and hours
Second (s)
The second is the SI base unit of time. It is used for timing, frequency and nearly every scientific time measurement.
Hour (h)
An hour is 60 minutes, or 3,600 seconds. It is used for work time, travel time and speeds such as km/h.
Both are units of time; the base unit used internally is s.
Notes
- A day is taken as exactly 86,400 s and a week as 7 days. Leap seconds, daylight-saving changes and calendar months/years are ignored.
- Durations cannot be negative.
