A "knot" is one nautical mile per hour and one nautical mile is defined as one minute of an angle along any of the earth's great circles. The obvious benefit is that using knots, you get your displacement with respect to the earth's coordinates. As an example, flying at 60 knots (groundspeed), east or west along the equator for one hour means you travel one degree of longitude in every hour. Usage of earth's cordinates is beneficial in aerial and oceanic navigation.
Cars use roads, which are well documented and its standard measurements (km or miles) suits fine.
As a general rule, wherever latitudes and longitudes are used for source and destination identification, knots are used. Between cities and towns, km or mile would suffice.
KIAS stands for Knots, Indicated Air Speed. And just for the record, one nautical mile is 1852 meters exactly.
20 knots is equivalent to approximately 10.29 meters per second.
To convert knots to meters per second, multiply the speed in knots by 0.514444. This conversion factor accounts for the difference in the units of measurement used for speed (nautical miles per hour for knots and meters per second).
Sailors in the past used a rope with knots tied on it to measure speed. They would throw the rope overboard from a moving ship and count how many knots passed through their hands in a certain amount of time. This helped them estimate how fast the ship was moving in knots.
A league ************************ That's a very old term! Nautical miles
Wind speed is often measured in knots because this unit is based on nautical miles, which are more relevant for maritime and aviation navigation. Knots provide a standardized measure that aligns with the distances traveled over water, making it easier for sailors and pilots to calculate their speed and distance. Additionally, using knots helps maintain consistency in international contexts, as it is widely recognized in meteorology and maritime operations.
The "knots of the child sailors" refers to the various knots that young sailors learned to tie as part of their training. These knots were essential for securing sails, ropes, and other equipment on a ship. Common knots included the bowline, square knot, and clove hitch, each serving specific purposes in sailing and maintaining safety on board. Mastery of these knots was crucial for effective seamanship, even for young crew members.
20 knots is equivalent to approximately 10.29 meters per second.
24 knots was the speed in which they were traveling when the sailors saw the ice burg
10.2888888 is the speed in meters per second of a ship traveling at 20 knots.
To convert knots to meters per second, multiply the speed in knots by 0.514444. This conversion factor accounts for the difference in the units of measurement used for speed (nautical miles per hour for knots and meters per second).
It originated in reference to the knots sailors tied in the rope used to measure the distance a ship travled. E2020's answer
"Sailors have long used ropes with weights on the end to measure depths in shallow water. Often they tied knots 6 feet (1 fathom) apart in the rope for ease of measurement. The number of knots let out gave the depth in fathoms once the weight hit the bottom. The first accurate physical measurements of the deep ocean bottom were made by Sir J. Clark Ross in 1840 who measured a depth of 4435 meters off Antarctica. Later, extensive depth recordings were taken by scientists on the H.M.S. Challenger using steam-driven winches with one inch hemp rope that did not tangle."
Knots is the form of measurement of the speed of boats. It was originally measured by a board being dropped in the water with a rope tied to it, the other end of the rope was tied to the stern of the boat. This rope had knots tied into it at 14.4 meters apart. The one sailor would use a 30 second glass sand timer while another would let the rope out behind the boat. When 30 seconds were up the number of knots on the rope that had gone thru the sailors hands were the speed they were traveling. Dividing that 14.4 meters by 30 seconds told them that one knot equaled 1.85166 kilometers per hour, or one nautical mile.
6.32766667 meters per second ==
.089 knots per meter or 11.23 meters per knots
The speed in meter/scond is 15x1800 m/3600 s = 7.5 meters/second where a Knot is a Nautical mile of 1800 meters/hour.
no, instead its growing at the rate of knots!
