Default "unit", "mass", "rate", "impulse", "momentum", "inertia"

A unit is One of anything; including the following:

A unit of mass is One kilogram; the ratio of One newton, dvided by One
meter per second, per second; Which is a unit of inertia: One
kilogram; the ratio of One newton, dvided by One meter per second, per
second.

A unit rate of speed, is One newton per second.

A unit of change in speed is the quotient of One unit of length,
divided by One second.

A rate of change in speed is a unit of change in speed, divided by a
unit of time.

A unit of impulse is the prodict of One newton per second.

A unit of momentum is the product of One unit of mass, and One unit of
change in speed.

I love the way you can make simple minded trash don sound so theological...
almost messianic its like god giving moses the ten commandments....

errors? well as for glaring dimensional inconsistencies (about as fatal a
flaw as is possible), then no don.... none at all mate

I personally think of a unit of quantity as *a unit* of anything - not
necessarily "kilograms" or "pounds" and so on. Unless the question in focus in
predefined in SI units. So talk about measurements of, say, dimensions of some
household furniture. So what is more important: 1mm, 1cm or 1m? Most people
would probably think differences within 1cm is more important than the others.
So furniture dimensions would most probably be quoted to the nearest cm, and
hence a unit dimension of furniture is 1cm.

Remember the differences between basic units and derived units! Some are mixed
up with 'dimensions' and 'units' can be confusing the read, eg, One unit of
length divided by one second...why not call it "...unit of time" or "One metre
divided...".
