Quantity K is metric for 1000. For units, it can also refer to Kelvin temperature. It can also refer to Kinetic energy.
A unit conversion ratio
the conversion factor merely changes the number in such a way that it fits the new units the physical quantity is not changed
The quantity (magnitude, numrical value) and the units (eg inch, metre, light year)
Nothing specifically is "done" to the variable; variables are generally used to represent either:* A quantity that is initially unknown (and should be solved for), or * A quantity that can be anything - to analyze what happens no matter what a certain value is.
they show the magnitude
Yes, a value can represent a quantity or amount.
A number is an arithmetic value used to represent quantity.
A ratio that's used to convert units always has the value of ' 1 ' with no units. If it were anything different, then you could not multiply it or divide it by any quantity without changing the value of the quantity, which is a basic no-no.

It could be but not necessarily. It is just a value and could represent that quantity of anything.
-the quantity (magnitude,numerical value). -the units (in inch,meter,light year).
The quantity (magnitude, numrical value) and the units (eg inch, metre, light year)
Yes. Although it can also be used for constants whose value is not yet known.
