Unit Description

Foot per second (ft/s)

Definition

Foot per second (ft/s) is a unit of speed expressing the number of feet traveled in one second. It provides more precise speed measurements in imperial systems and is commonly used in engineering and scientific applications within imperial unit systems.

History

Foot per second developed as a more precise alternative to mile per hour for engineering and scientific applications in imperial systems. It provided appropriate scaling for applications requiring finer speed resolution than mph could practically provide.

Current Use

Ft/s is used in engineering calculations, ballistics, fluid dynamics, and scientific applications within imperial systems. It's standard for projectile velocities, fluid flow rates, and engineering applications requiring precise speed measurements in imperial units.

Mile per hour (mph)

Definition

Mile per hour (mph) is a unit of speed expressing the number of miles traveled in one hour. It's the primary speed unit used in the United States and United Kingdom, providing a familiar measure for vehicle speeds and general motion in imperial systems.

History

Mile per hour developed with the imperial system and became standard in English-speaking countries. It provided a practical scale for measuring speeds using familiar mile distances, becoming deeply embedded in American and British transportation systems and regulations.

Current Use

Mph is extensively used in the United States and United Kingdom for vehicle speed limits, automotive speedometers, weather reporting, and general speed measurements. It's standard for road signs, traffic regulations, and vehicle specifications in countries using imperial units.
