1 nautical mile per hour (by definition), 1 852.000 metres per hour (exactly), [5] 0.51444 metres per second (approximately), 1.15078 miles per hour (approximately), 20.25372 inches per second (approximately) 1.68781 feet per second (approximately). The length of the internationally agreed nautical mile is 1 852 m.
A basic airspeed indicator with the indicated airspeed (IAS) indicated in knots ("Kt" or "Kts" or "KIAS") -- the most common unit of measure for airspeed. Some airspeed indicators in aircraft prior to the mid-1970s indicate in miles per hour plus knots (1 knot = 1.15 mph) or kilometers per hour (1 knot = 1.85 km/h).
Most United States Navy ships of the post–World War II era have actually carried 2 or 3 bells: the larger bell engraved with the ship's name, mounted on the forecastle, and smaller bells in the pilot house and at the quarterdeck at the 1MC (public address) station, for use in making shipwide announcements and marking the time. The larger bell ...
The sensitivity of a microphone is usually expressed as the sound field strength in decibels (dB) relative to 1 V/Pa (Pa = N/m 2) or as the transfer factor in millivolts per pascal (mV/Pa) into an open circuit or into a 1 kiloohm load. [citation needed] The sensitivity of a hydrophone is usually expressed as dB relative to 1 V/μPa. [7]
The airspeed indicator (ASI) or airspeed gauge is a flight instrument indicating the airspeed of an aircraft in kilometres per hour (km/h), knots (kn or kt), miles per hour (MPH) and/or metres per second (m/s). The recommendation by ICAO is to use km/h, however knots (kt) is currently the most used unit.
Knot (unit), a unit of speed equal to one nautical mile per hour; Kotlin (programming language), uses the .kts file extension for Kotlin script files; Brevig Mission Airport (IATA: KTS) Potassium thiosulfate, a chemical compound commonly abbreviated as KTS.

For example, while six bells have 720 permutations, eight bells have 40,320; furthermore, 10! = 3,628,800, and 12! = 479,001,600. Estimating two seconds for each change (a reasonable pace), one finds that while an extent on six bells can be accomplished in half an hour, an extent on eight bells should take nearly twenty-two and a half hours.
Airspeed is commonly given in knots (kn). Since 2010, the International Civil Aviation Organization (ICAO) recommends using kilometers per hour (km/h) for airspeed (and meters per second for wind speed on runways), but allows using the de facto standard of knots, and has no set date on when to stop.
