Knots

Definition of Knots

Knots, commonly denoted kn, is a unit of speed equal to one nautical mile per hour, exactly 1.852 km/h (approximately 1.151 mph or 0.514 m/s). It is the standard unit of speed used in meteorology, and in maritime and air navigation. A vessel travelling at 1 kn along a meridian travels approximately one minute of geographic latitude in one hour.

How to Convert Knots

To convert knots to other units of speed, we need to multiply or divide by the corresponding conversion factors. For example, to convert knots to kilometers per hour, we need to multiply by 1.852, since there are 1.852 kilometers in one nautical mile. To convert knots to meters per second, we need to divide by 3.6, since there are 3.6 seconds in one hour.

Here are some examples of how to convert knots to other units of length in the US Standard system and the SI system:

• To convert 10 kn to kilometers per hour (km/h), we multiply by 1.852: 10 kn x 1.852 = 18.52 km/h
• To convert 20 kn to miles per hour (mph), we multiply by 1.1507794480235, since there are 1.1507794480235 miles in one nautical mile: 20 kn x 1.1507794480235 = 23.01558896047 mph
• To convert 30 kn to feet per second (fps), we multiply by 1.6878098571012, since there are 1.6878098571012 feet in one meter: 30 kn x 1.6878098571012 = 50.634295713036 fps
• To convert 40 kn to meters per second (m/s), we divide by 3.6: 40 kn / 3.6 = 11.111111111111 m/s
• To convert 50 kn to meters per minute (m/min), we multiply by 60, since there are 60 minutes in one hour: 50 kn x 60 = 3,000 m/min
• To convert 60 kn to centimeters per second (cm/s), we multiply by 100, since there are 100 centimeters in one meter, and divide by 3.6: 60 kn x 100 / 3.6 = 5,000 cm/s

Where Knots Are Used

Knots are used in various fields of science and technology where the speed and direction of movement of objects or phenomena are measured or applied in relation to water or air currents. For example:

• In meteorology, knots are used to measure wind speed and direction, as well as the speed and direction of storms, hurricanes, and other weather phenomena.
• In maritime navigation, knots are used to measure the speed and direction of ships, boats, submarines, and other watercraft, as well as the speed and direction of ocean currents, tides, and waves.
• In air navigation, knots are used to measure the speed and direction of aircraft, helicopters, rockets, satellites, and other aerospace vehicles, as well as the speed and direction of air currents, jet streams, and wind shear.

History of Knots

The origin of knots as a unit of speed can be traced back to the ancient practice of measuring the speed of ships by using a device called a chip log or log-line. This device consisted of a wooden board attached to a rope with knots tied at regular intervals along its length. The board was thrown overboard from the stern of the ship and allowed to drag behind it while the rope was let out for a fixed amount of time (usually measured by a sandglass). The number of knots that passed over the rail of the ship during that time indicated the speed of the ship in nautical miles per hour.

The first recorded use of this method was by the Phoenicians around the second millennium BCE. The device was later improved and standardized by various civilizations such as the Greeks, Romans, Arabs, Vikings, Chinese, and Europeans. The length of the nautical mile and the spacing of the knots varied from place to place and from time to time until they were fixed by international agreement in the late nineteenth century.

The term knot was derived from the Old English word cnotta meaning “a knot”. It was first used as a unit of speed by English sailors in the early seventeenth century.

Example Conversions of Knots to Other Units

Here are some examples of how to convert knots to other units of speed, using the conversion factors given above:

• To convert 300 kn to feet per second, we multiply by 1.6878098571012: 300 kn x 1.6878098571012 = 506.34295713011 fps
• To convert 400 kn to meters per second, we divide by 3.6: 400 kn / 3.6 = 111.11111111111 m/s
• To convert 500 kn to meters per minute, we multiply by 60: 500 kn x 60 = 30,000 m/min
• To convert 600 kn to centimeters per second, we multiply by 100 and divide by 3.6: 600 kn x 100 / 3.6 = 50,000 cm/s
• To convert 700 kn to millimeters per minute, we multiply by 1000, since there are 1000 millimeters in one meter, and multiply by 60: 700 kn x 1000 x 60 = 42,000,000 mm/min

Centimeters per minute: A unit of speed

Centimeters per minute (cm/min) is a unit of speed or velocity in the International System of Units (SI). It measures how fast an object is moving by calculating the distance traveled in centimeters divided by the time taken in minutes. For example, if a snail travels 6 centimeters in 3 minutes, its speed is 2 cm/min.

How to convert centimeters per minute

Centimeters per minute can be converted to other units of speed or velocity by using simple conversion factors. Here are some common units and their conversion factors:

• Meters per second (m/s): To convert from cm/min to m/s, divide by 6000. To convert from m/s to cm/min, multiply by 6000. For example, 1 cm/min is equal to 0.000166667 m/s, and 10 m/s is equal to 60000 cm/min.
• Kilometers per hour (km/h): To convert from cm/min to km/h, divide by 100000. To convert from km/h to cm/min, multiply by 100000. For example, 1 cm/min is equal to 0.0006 km/h, and 50 km/h is equal to 833333.333 cm/min.
• Miles per hour (mph): To convert from cm/min to mph, multiply by 0.000372823. To convert from mph to cm/min, divide by 0.000372823. For example, 1 cm/min is equal to 0.000372823 mph, and 30 mph is equal to 80467.2 cm/min.
• Knots (kn): To convert from cm/min to kn, multiply by 0.000323974. To convert from kn to cm/min, divide by 0.000323974. For example, 1 cm/min is equal to 0.000323974 kn, and 15 kn is equal to 46296.296 cm/min.
• Feet per minute (ft/min): To convert from cm/min to ft/min, divide by 30.48. To convert from ft/min to cm/min, multiply by 30.48. For example, 1 cm/min is equal to 0.0328084 ft/min, and 10 ft/min is equal to 304.8 cm/min.
• Inches per minute (in/min): To convert from cm/min to in/min, divide by 2.54. To convert from in/min to cm/min, multiply by 2.54. For example, 1 cm/min is equal to 0.393701 in/min, and 20 in/min is equal to 50.8 cm/min.

Where centimeters per minute are used

Centimeters per minute are mainly used in science and engineering to measure the flow rate of fluids and gases.

For example, the standard cubic centimeter per minute (SCCM) is a unit used to quantify the flow rate of a fluid at standard conditions of temperature and pressure.

The flow rate of blood through a capillary is often measured in centimeters per minute.

The flow rate of air through a wind tunnel is often measured in centimeters per second, which is equivalent to centimeters per minute divided by 60.

Definition of centimeters per minute

According to the SI definition, one centimeter per minute is the speed of a body that covers a distance of one centimeter in a time of one minute.

Mathematically, it can be expressed as:

v = s / t

where v is the speed or velocity in centimeters per minute, s is the distance traveled in centimeters, and t is the time taken in minutes.

History of centimeters per minute

The concept of speed or velocity has been studied since ancient times by philosophers and scientists such as Aristotle, Galileo, Newton, etc.

The centimeter was originally derived from the French centimeter which was defined as one hundredth of a meter.

The meter was originally derived from the French meter which was defined as one ten-millionth of the distance from the equator to the North Pole.

The minute was originally derived from the Babylonian sexagesimal system which divided an hour into sixty minutes.

The combination of these two units resulted in the centimeter per minute as a unit of speed or velocity.

The centimeter per minute was officially adopted as part of the SI system in 1960.
