ft/s to Mach

Foot per second

• Definition: Foot per second (ft/s) is a unit of speed that expresses the distance traveled in feet during one second of time.

• Symbol: The symbol for foot per second is ft/s.

• Usage: This unit is commonly used in various fields such as engineering, physics, and everyday life to quantify speed, especially in the United States.

Mach 20c 1 atm

• Definition: Mach 20c 1 atm refers to a speed that is 20 times the speed of sound at sea level, under standard atmospheric conditions, which is approximately 343 meters per second or 1125.33 feet per second.

• Symbol: The symbol for Mach is “M,” so Mach 20 is represented as M20.

• Usage: This unit is typically used in aerospace and aeronautical engineering to describe speeds of aircraft and spacecraft at hypersonic levels.

Origin of the foot per second

• The foot per second unit has its origins in the imperial system of measurement, which dates back to the Roman Empire. The foot itself has been used as a standard measure since ancient times, and the concept of speed was later quantified as distance over time.

Origin of the mach 20c 1 atm

• The concept of Mach was introduced in the 19th century by Austrian physicist Ernst Mach. The Mach number is a dimensionless unit used to represent the speed of an object relative to the speed of sound. The designation of Mach 20c specifically relates to speeds that are 20 times that of sound in standard atmospheric conditions.
