Distance: Meters (or metres)
Speed & velocity (meters per second). velocity also needs a direction but that isn't defined by SI units.
SI units: time:second length: meter speed:meter/second velocity:meter/second.
(any unit of length) / (any unit of time) is a unit that can be used for the magnitude (size) of velocity, and must always be accompanied by a description of direction. Without it, all you have is a speed, not a velocity.
What are the SI units used to measure acceleration.
In a system of units such as the SI, BASE UNITS are defined; other units are derived from those.For example, in the SI, the meter, the kilogram, and the second are base units; the units for area (meters squared), for speed and velocity (meters/second), etc. are derived from the base units. Which units are base units, and which units are derived units, really depends on how the unit is defined. For example, in the SI, pressure is a derived unit; but you can just as well invent a system in which pressure is a base unit, and some other units, that are base units in the SI, are derived in this new system.
Meter per secondThere is no standard SI unit for velocity actually. It is a derived unit. Velocity is distance traveled per time together with the direction of motion. The SI unit of distance is the meter (m) and the SI unit of time is the second (s).So the units of velocity in SI units is meters/second (m/s), or ms-1See the Related Questions link to the left "What are all the SI units" for more information about SI units.CommentDerived units are SI units.
SI units: time:second length: meter speed:meter/second velocity:meter/second.
Velocity is comprised of a speed part and a direction part. (any SI unit of length)/(any SI unit of time) is a unit of speed. The simplest one, in SI base units, would be meters/second . Direction is most often stated as an angle.
The SI unit for velocity is m/s. Therefore the SI units for velocity squared would be m2/s2.
Velocity is the measure of speed in a given direction. Although the SI measurement units for both are metres per second, there must be an explicit or implied direction for velocity.

The velocity is distance per unit time and the SI unit is m/s.
Volume is a fundamental quality because of volume per mass. Other familiar fundamental qualities include mass, velocity, speed, m3, cubic meter, and density.AnswerThere is no such thing as a 'fundamental unit' in SI. Units are either 'base units' or 'derived units'. In SI, volume is measured in cubic metres, where the metre is the base unit of length.

"si" stands for the International System of Units, which is the modern form of the metric system. It is based on seven base units, one of which is the meter for length.
