Quantity or

exist as a
multitude or magnitude,
which illustrate discontinuity and continuity.

analysis of the
relationships between different physical quantities by
identifying their base
quantities (such as length, m****, time, and
electric current)...

relationships between units. The
choice of
which and even how many
quantities to use as base
quantities is not
fundamental or even
unique – it is a
matter of convention...
- equivalent,
because a
ratio of
power quantities is
equal to the
square of the
corresponding ratio of root-power
quantities.[citation needed]
