What is Knot?

A knot is a unit of speed used in navigation and aviation, representing one nautical mile per hour. It’s commonly used in maritime and aerial navigation due to its practicality in measuring speeds over water or through air currents. One knot is equivalent to approximately 1.15078 miles per hour or 1.852 kilometers per hour.

Knot Formula and Symbol

The formula to convert knots to other units of speed is:

Speed (in knots) = Distance (in nautical miles) / Time (in hours) 1 knot = 1 nautical mile per hour

The symbol used to represent knots is “kn” or “kt“.

Conversion of Knot into Other Units

Conversion of Knot into Other Units
From/To (unit)Conversion Formula
1Knot to Kilometers per Hour (km/h)kt × 1.852
1Knot to Miles per Hour (mph)kt × 1.150779
1Knot to Meters per Second (m/s)kt × 0.514444

Knot to Kilometers per Hour (km/h)

1Knot = 1.852 Kilometers per Hour (km/h)

One knot, a unit of speed used in navigation, equals 1.852 kilometers per hour (km/h). It represents the speed of one nautical mile per hour, commonly used in maritime and aviation contexts.

Knot to Miles per Hour (mph)

1Knot = 1.150779 Miles per Hour (mph)

One knot, a unit of speed in navigation, equals approximately 1.150779 miles per hour (mph). It’s commonly used to measure the speed of vessels and aircraft relative to the water or air.

Knot to Meters per Second (m/s)

1Knot = 0.514444 Meters per Second (m/s)

One knot, a unit of speed commonly used in navigation, is equivalent to approximately 0.514444 meters per second (m/s), representing the speed of one nautical mile per hour.

Examples of Knot

  1. A sailboat cruising at 7 knots on a calm sea.
  2. The speed of a commercial airliner during takeoff can reach up to 150 knots.
  3. A fishing trawler travels at 5 knots while searching for its catch.
  4. A yacht racing in a regatta achieves speeds of over 20 knots.
  5. A military vessel patrols coastal waters at 25 knots.
  6. A speedboat zips along the river at 30 knots, creating waves in its wake.
  7. A submarine moves stealthily underwater at 15 knots.
  8. A rescue helicopter flies at 120 knots to reach a distressed vessel.
  9. A passenger ferry transports commuters across the bay at 35 knots.
  10. A small dinghy sails at 4 knots, propelled by the wind.

Types of Knot

  1. Clove Hitch: Used for securing lines temporarily to posts or poles.
  2. Square Knot (Reef Knot): Ideal for joining two ropes of the same diameter.
  3. Bowline Knot: Creates a secure loop at the end of a rope, often used in sailing.
  4. Figure Eight Knot: Prevents ropes from slipping through a loop or a hole.
  5. Sheet Bend: Joins two ropes of different diameters.
  6. Double Fisherman’s Knot: Used for joining two ends of a cord or rope securely.
  7. Taut Line Hitch: Allows adjustment of the tension in a line, commonly used in camping.
  8. Trucker’s Hitch: Creates a mechanical advantage for securing loads.
  9. Timber Hitch: Used for attaching a rope to a cylindrical object like a log or pole.
  10. Fisherman’s Knot: Joins two lines or ropes of similar diameter, commonly used in fishing.


What are the most common knots used?

Common knots include the square knot, bowline, clove hitch, figure-eight knot, and sheet bend.

How do I choose the right knot for my needs?

The choice of knot depends on factors such as the type of rope, the intended use, and the load it will bear. Researching specific knots for your activity is advisable.

What are knots used for?

Knots have various applications, including sailing, camping, climbing, fishing, boating, and rescue operations.

Are there different categories of knots?

Yes, knots are often categorized based on their specific function, such as binding, loop, stopper, and hitch knots.
