Some "measurements" or units that are scalar include mass, length, time, volume, etc. A scalar unit means that they are measurable values, of course, but they don't necessarily have a direction. Vector measurements or units include force, velocity, acceleration, etc. both have a magnitude and a DIRECTION.

Scalars are quantities that are fully described by a magnitude (or numerical value) alone. Vectors are quantities that are fully described by both a magnitude and a direction.
