If you don't know their equivalence, then you can either get a common denominator, and compare the numerators. Or you can divide and convert them all to decimal form and then compare.
You can convert units of length to units of length, and units of area to units of area. But it doesn't make sense to convert between units of length and units of area.
It doesn't make sense to convert that. You can convert units of length to units of length, for example; but you can't convert a pure number to a length.
It doesn't make sense to convert that. You can only convert units of the same kind, e.g., units of length to units of length; units of area to units of area; units of time to units of time, etc.
You can't convert that. You can only convert units that measure the same type of thing - for example, units of length to units of length, units of mass to units of mass, units of time to units of time, etc.
You use conversion factors.

Some customary units of length include inches, feet, yards, and miles in the United States. In other countries, units like centimeters, meters, and kilometers are common for measuring length.

There are different ways of converting weight, length, volume etc.
It doesn't make sense to convert units that measure completely different things. You can only convert units of length to units of length, units of mass to units of mass, etc.
You can't convert that. You can only convert units that measure the same type of thing - for example, units of length to units of length, units of mass to units of mass, units of time to units of time, etc.
Units of weight do not convert into units of length. Weight and length are different things.
