The knot per second (kn/s) is a unit of velocity that measures speed in nautical miles per hour. It is commonly used in maritime and aviation contexts, where it is essential to understand the speed of vessels and aircraft relative to the water or air. One knot is equivalent to one nautical mile per hour, which is approximately 1.15078 miles per hour.
The knot is a standardized unit of measure recognized internationally. The International System of Units (SI) does not include the knot as a base unit; however, it is widely accepted in navigation and meteorology. The symbol for knot is "kn," and when expressed in terms of seconds, it becomes "kn/s."
The term "knot" originates from the practice of measuring a ship's speed by counting the number of knots tied in a rope that was thrown overboard. This method dates back to the 17th century and has evolved into the modern use of the knot as a unit of speed. The adoption of the knot in aviation and maritime navigation has made it an essential component of global transportation.
To convert speed from knots to kilometers per second, you can use the following formula:
1 kn = 0.000514444 km/s
For example, if a vessel is traveling at 20 knots, the calculation would be:
20 kn × 0.000514444 km/s = 0.01028888 km/s
Knot per second is primarily used in maritime and aviation contexts. It helps navigators and pilots understand their speed relative to the earth's surface, which is crucial for safe and efficient travel. Whether you're sailing a boat or flying an aircraft, knowing your speed in knots can help you make informed decisions.

The astronomical unit per hour (AU/h) is a unit of measurement used to express velocity in terms of astronomical units traveled in one hour. One astronomical unit (AU) is approximately the distance from the Earth to the Sun, roughly 149.6 million kilometers. This unit is particularly useful in astrophysics and astronomy, where distances between celestial bodies are vast and often measured in astronomical units.
The astronomical unit is a standard unit of measurement in the field of astronomy. The International Astronomical Union (IAU) has defined the astronomical unit as precisely 149,597,870.7 kilometers. By standardizing this unit, scientists and researchers can communicate distances and velocities in a consistent manner, facilitating collaboration and understanding across various scientific disciplines.
The concept of the astronomical unit dates back to ancient civilizations, but it was not until the 17th century that it began to be used in a standardized way. The term "astronomical unit" was first coined in the 19th century, and its definition has evolved with advancements in technology and our understanding of the solar system. The introduction of the AU/h unit allows for a more practical application of this measurement in the context of time, making it easier to calculate velocities of celestial objects.
To convert a velocity from kilometers per hour (km/h) to astronomical units per hour (AU/h), you can use the following formula:
[ \text{Velocity (AU/h)} = \frac{\text{Velocity (km/h)}}{149,597,870.7} ]
For example, if a spacecraft is traveling at a speed of 300,000 km/h, the calculation would be:
[ \text{Velocity (AU/h)} = \frac{300,000}{149,597,870.7} \approx 0.00201 \text{ AU/h} ]
The AU/h unit is primarily used in astrophysics to describe the velocities of spacecraft, comets, and other celestial bodies. It allows astronomers to easily compare speeds and distances in a context that is meaningful within the vastness of space.
