It doesn't even matter what unit is chosen as long as it is kept the same across.

Comparing Smarties to M&Ms is super easy if both have to use price per pound, price per oz, price per g or price per kg. Who cares if the price per kg would be $0.031.as long as I can see it's $0.028 for the other for the same unit without doing math.
