Conversion formula
Linear unit conversions use standardized factors; many are exact by definition (e.g., 1 in = 25.4 mm, 1 ft = 0.3048 m).
Common mistakes
- Assuming all ‘days’ are equal in astronomical contexts; civil day is standardized at 24 h.
Unit facts
- Hour (h): One hour equals 60 minutes (3,600 s); civil time standard.
- Second (s): The second (s) is the SI base unit of time; defined via the cesium-133 transition.
About Time
Timekeeping blends SI seconds with civil conventions like minutes, hours, and days. Precision timing underpins GPS and networks, while everyday planning uses calendar intervals and weeks.
About Hour (h)
Hour (h)
Equals 60 minutes (3,600 s). Used universally in timetables, billing, and shift scheduling.
History: Civil time standardized hours with mechanical clocks; now coordinated by atomic time.
About Second (s)
Second (s)
SI base unit of time defined via the cesium-133 hyperfine transition. Forms the backbone of GPS, telecoms, and scientific timing.
History: Atomic timekeeping led to redefinition in the 1960s; future redefinitions may use optical clocks with even better stability.
