  3. Foot per second - Wikipedia

    en.wikipedia.org/wiki/Foot_per_second

    The foot per second (plural feet per second) is a unit of both speed (scalar) and velocity (vector quantity, which includes direction). [1] It expresses the distance in feet (ft) traveled or displaced, divided by the time in seconds (s). [2] The corresponding unit in the International System of Units (SI) is the meter per second.

    The beard-second is a unit of length inspired by the light-year, but applicable to extremely short distances such as those in integrated circuits. It is the length an average beard grows in one second. Kemp Bennett Kolb defines the distance as exactly 100 angstroms (10 nanometres), [8] as does Nordling and Österman's Physics Handbook. [9]

  8. Speed of sound - Wikipedia

    en.wikipedia.org/wiki/Speed_of_sound

    The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. More simply, the speed of sound is how fast vibrations travel. At 20 °C (68 °F), the speed of sound in air, is about 343 m/s (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or 1 km in 2.91 s or one mile in 4.69 s.
