How do I compare prices by unit?

Divide each price by its quantity to get price per unit, then compare. $3.50 for 500 g is $0.007/g; $6 for 1000 g is $0.006/g — B is cheaper per gram.

Why use the same unit?

Only compare price per gram with price per gram (or per ml, per item). Mixing units gives a meaningless comparison.
