Say a 5-pound rice bag costs $4.00 at your local store. That means the cost of rice per pound is:

Price per pound ⟹ Price per pound = \frac{Total cost}{Total weight} = \frac{$4.00}{5 lbs} = 0.8 = $0.80

Price per pound⟹Price per pound=Total weightTotal cost=5 lbs$4.00=0.8=$0.80

The formula for calculating the price per unit volume is similar:

Cost per unit volume = \frac{Total cost}{Total volume}

Cost per unit volume=Total volumeTotal cost

For example, if a gallon of milk costs $3.50, what does a fluid ounce (fl oz) cost?

Price per fluid ounce ⟹ Price per fluid ounce = \frac{Total cost}{Total volume} = \frac{$3.50}{1 US gal} = \frac{$3.50}{128 fl oz} = 0.027 \equiv $0.03

Price per fluid ounce⟹Price per fluid ounce=Total volumeTotal cost=1 US gal$3.50=128 fl oz$3.50=0.027≡$0.03

We bet you can already guess what the formula for calculating unit cost per item is:

Cost per egg ⟹ Price per egg = \frac{Total cost}{Number of eggs} = \frac{$4.40}{18 eggs} = 0.244 \equiv $0.24

Cost per egg⟹Price per egg=Number of eggsTotal cost=18 eggs$4.40=0.244≡$0.24
