Per Unit: Unit Price Compare

The 900 g pack is 210. The 1.5 kg pack is 320. Which one actually costs less?

Per Unit does that sum for you while you are standing in the aisle. Type the price and the pack size for each option and it ranks them by what you pay per kilogram, per litre or per piece, with the better buy marked and the difference shown as a percentage, so you can see whether the bigger pack is worth it or not.

It handles the units the way shelves actually label them. Grams against kilograms, millilitres against litres, and loose pieces against multipacks are all converted before anything is compared. Weight and volume are kept in separate rankings, because a price per kilo and a price per litre are not the same measurement, and pretending otherwise gives you a wrong answer.

Compare as many packs as you like, not just two. Give each one the brand or shop name so the result reads properly. Save a comparison to look up on the next trip, and share the verdict as plain text with whoever asked you to pick up the shopping.

Pick your currency symbol once and it stays.
