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.

Meters Per Hour

Definition of Meters Per Hour

Meters per hour (m/h) is a unit of speed that measures how fast something is moving in terms of meters per unit of time. It is a metric unit that is derived from the base unit of length, the meter, and the base unit of time, the hour. It is rarely used however, as the units of meters per second and kilometers per hour are considered sufficient for most situations.

One meter per hour is equal to 0.00027777777777778 meters per second, or 0.001 kilometers per hour. It can also be converted to other units of speed, such as feet per second, miles per hour, or knots, by using appropriate conversion factors.

How to Convert Meters Per Hour

To convert meters per hour to other units of speed, we need to multiply or divide by the corresponding conversion factors. For example, to convert meters per hour to feet per second, we need to multiply by 0.0009113444153, since there are 0.0009113444153 feet in one meter. To convert meters per hour to kilometers per hour, we need to multiply by 0.001, since there are 0.001 kilometers in one meter.

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

• To convert 10 m/h to feet per second (fps), we multiply by 0.0009113444153: 10 m/h x 0.0009113444153 = 0.009113444153 fps

• To convert 50 m/h to meters per minute (m/min), we divide by 60, since there are 60 minutes in one hour: 50 m/h / 60 = 0.833333333333 m/min
• To convert 60 m/h to centimeters per second (cm/s), we multiply by 100, since there are 100 centimeters in one meter, and divide by 3600: 60 m/h x 100 / 3600 = 1.666666666667 cm/s

Where Meters Per Hour Are Used

Meters per hour are mainly used for measuring very slow speeds or velocities of objects or phenomena that move in terms of meters per unit of time. They are often used in scientific fields such as geology, biology, astronomy, and physics, where the speed or velocity of an object or phenomenon is very small compared to the usual units of speed.

For example, a glacier may have a speed of a few meters per hour, which means that it moves a few meters in one hour. A snail may have a speed of up to 47 meters per hour, which means that it can travel up to 47 meters in one hour. A planet may have an orbital velocity of thousands of meters per hour, which means that it covers thousands of meters along its orbit in one hour.

Meters per hour are also used in some other fields where the speed or velocity of an object or phenomenon is measured in terms of meters per unit of time.

History of Meters Per Hour

The origin of meters per hour as a unit of speed can be traced back to the development of the metric system and the meter as a unit of length in the late eighteenth century. The meter was defined as one ten-millionth of the distance from the equator to the North Pole along a meridian through Paris.

The term meter first appeared in English in 1797, but it was not until later in the early nineteenth century that the use of meters per hour became more common; before that, other units such as feet per hour or leagues per hour were preferred for expressing speed.

Meters per hour have been used ever since as a standard unit of speed for measuring very slow speeds or velocities of objects or phenomena that move in terms of meters per unit of time. They have also been adopted by some international organizations and conventions, such as the International System of Units and the International Astronomical Union.
