Examples
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.
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.

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.
