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
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.
Units of speed can be what?
Units of speed can be expressed in miles per hour (mph), kilometers per hour (km/h), meters per second (m/s), or knots.
Is what units is speed expressed?
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.
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 units are used for speed in the laboratory?
Speed in the laboratory is typically measured in units of meters per second (m/s) or centimeters per second (cm/s). Sometimes, it can also be expressed in micrometers per second (μm/s) for very small particles or organisms.
What are the units of probability density?
The units of probability density are typically expressed as the reciprocal of the units of the variable being measured. For example, if the variable is measured in meters, the units of probability density would be expressed as 1/meters.
What is the concentration of the solution in units of micromolar?
The concentration of the solution is expressed in micromolar units.
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).
