Second per foot [s/ft] to Minute per kilometre [min/km] Converter

Definition: Second per foot (s/ft) is a unit of kinematic viscosity. It represents the time in seconds required for a fluid to flow a distance of one foot under the influence of gravity.

History/origin: The second per foot unit likely arose from practical applications in fields such as hydraulics and fluid dynamics, where measuring flow rates and viscosities was crucial. Its exact origins are difficult to pinpoint but are tied to the development of techniques for quantifying fluid behavior.

Current use: While not as widely used as other viscosity units like centistokes or Pascal-seconds, second per foot may still be encountered in older literature, specific industrial contexts, or specialized applications within engineering and physics related to fluid flow and material characterization.

Definition: Minute per kilometre (min/km) is a unit of pace, expressing the time taken to travel one kilometre. It is commonly used in running and walking to indicate speed over distance.

History/origin: Minute per kilometre is a practical unit derived from the metric system for indicating pace in endurance activities. It allows for easy comparison of performance over a fixed distance.

Current use: Min/km is used by runners and walkers to track and compare their pace. It is also used in fitness apps and sports tracking devices to provide feedback on performance during training and races.
