Some of the most popular units of speed are
-- miles per hour
-- feet per second
-- kilometers per hour.
But (any unit of length or distance) divided by (any unit of time) is a
perfectly good unit of speed, and armed with that knowledge, you can
easily make up your own, to amuse and astound your friends with.
Here are some:
-- meters per minute
-- furlongs per fortnight
-- miles per month
-- smoots per century
-- Indy-laps per day
-- yards per yocto-week
Speed is expressed in units of Knots = 2 meters/second or Nautical Miles/hour.

You can express or determine the speed of wind using the Beaufort Wind Scale.

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.
Mass is expressed in grams in the SI system and slugs in the English system. (these are the base units obviously multiples of these units exist. ex: kg). Volume is expressed as a cubic of any unit of length ex: M^3.
speed =distance/speed .units to express speed are m/s and km/hr.

The most common units used to express the volume of gas are liters (L) and cubic meters (m³). Other units such as milliliters (mL) and cubic centimeters (cm³) are also used for smaller volumes.
