About speed converter

We use different speed units in everyday life. Speed is relevant unit to keep track of time passage on certain length, for example how long it takes to walk into work.
This page will give you all the necessary information you need to know about speed, and how to convert different speed units.

How to use the speed converter?

You can convert speeds units by using our speed convertor. This calculator works with knots, kilometers per hour, meters per second, miles per hour and many more. Make calculations easily by choosing a speed unit and then inserting the temperature amount.

What is speed?

Speed is a quantity that refers to how fast an object is moving. It can be considered the rate at which an object moves across a distance. Speed doesn't have a direction.
Definition of speed

What is the formula of speed?

Speed is the unit of distance divided by time.
Formula of speed
s = d / t
s = speed
d = travelled distance
t = time elapsed

What is the difference speed and velocity?

Speed is the time rate at which an object moves along a path. Speed is not aware of direction.
Velocity is a vector quantity that is aware of direction. If you ran across the room and then got back to where you were before, then your velocity would be zero since it didn't change from the beginning and end of the interval.
Speed and velocity

What is difference between average speed and instaneous speed?

Instantaneous speed is equivalent to instantaneous velocity without elapsed time and it is always positive. Average speed is the distance divided by elapsed time.

What are kilometers?

The kilometre is a unit of length that is equal to one thousand meters. It is used to represent distances between different regions in most of the world.

What are miles?

A mile is a unit of length and it equals to 1.609 kilometers.

What are knots?

The knot is a unit of speed that's equal to one nautical mile (1.852 km) per hour, or 1.151 miles per hour.

Why ship’s speed measured in knots?

Before the modern era, sailors have been using a floating object to measure their vessel’s speed. They would then throw it over their bow and count the time it took for the object to pass before they stopped. The method, which was known as a Dutchmen’s log, became known as a chip log.
For years, different nations have had varying standards for the exact measurement of the nautical mile. In 1929, the International Nautical Mile was established, which became the US standard in 1954.

What is the speed of light?

The speed of light, which is the speed at which light waves propagate through various materials, is a fundamental property of nature. It is considered the limiting velocity of the universe.
During ancient times, scientists believed that the speed of light could travel at infinite speed.
In the first half of the 19th century, a number of scientists carried out experiments to determine the speed of light. Some of these techniques, such as the one used by Hippolyte Fizeau in 1849, were very accurate. In 1983, the International Commission on weights and measures established the speed of light at 299,792,458 meters per second.

What is the fastest sailboat?

The fastest monohull sailboat in the world is called V.O.60. It's a 64-foot vessel that can reach velocities of over 36 knots. The boats hull is made of resin, and the mast, boom, and spinnaker pole are made of carbon fiber. The sails are vacuum-formed composite. Bruce Farr designed it to be as fast as a needle-nose boat.
