The official unit for speed is meters/second. Any other combination of units, where you divide distance/time, may also be used. One such unit that is commonly used is kilometers/hour. Some units used for speed don't explicitly reference distance and time; for example, a certain fraction of the speed of light in a vacuum, or the unit called "knots" which is used for ships.

Angular Measure
What is expressed in units?
Everything measureable has a unit it is measured in.
What is the unit of measurement of a anamometer?
The "anemometer" is an instrument used to measure wind speed. Its output is a speed measurement, and may be expressed in any convenient unit of speed, such as 'miles per hour', 'kilometers per hour', 'feet per second', etc. Anemometers are sold in units of "each".
How is momentum expressed in imperial or English units?
slug-feet/second
Why is light measured in distance and not in time?
-- The distance that light travels in some amount of time is expressed in units of distance. -- The time that it takes light to cover some amount of distance is expressed in units of time. -- The speed of light is expressed in units of speed . . . distance/time
Speed is expressed in units of what?
speed =distance/time and units of speed can differ depending on the circumstance. in science we usually measure speed as meters per second (m/s) can also be written ms^-1.
Directions are expressed as units of?

What are Units of particle motions?
"Motion" can be expressed in units of speed. Or it might refer to momentum - in which case you would use any unit of mass x velocity.
What is expressed in square units?
The surface area of a shape is expressed in square units.
What are three units of measurment?
Here are some international units of measurement:Mass is expressed in kilograms.Length and distance is expressed in meters.Time is expressed in seconds.Electrical current is expressed in amperes.Speed is expressed in meters/second.
Average weight of an element expressed in atomic mass units?
Average weight of an element expressed in Atomic Mass units.
How is the volume of solid objects commonly expressed?
It is expressed in cubic units.
What is the speed of light measured in?
This is commonly expressed in meters/second, kilometers/second, or miles/second. To use SI units, use meters/second.
What are the four units of speed?
what are the four units of speed
How is rpm related to speed?
More rpm means more speed, but the speed is also related to the diameter of the rotating object. The exact formula is: speed = angular speed x radius (assuming compatible units are used: for example, speed in meters/second, angular speed in expressed in radians/second, radius in meters).
What are two units of measure for speed?
In order to measure speed, a unit for distance and a unit for time must be used. Common units with which speed is expressed are meters per second (m/s), miles per hour (mph), and kilometers per hour (km/h).
