TopToolsAiCompare two products by their true price per unit (per gram, per litre, per piece) to instantly see which one is actually the better deal, regardless of pack size. A 1kg pack priced at PKR 950 works out to PKR 950 per kg, while a 750g pack at PKR 720 works out to PKR 960 per kg — despite looking cheaper on the shelf, the smaller pack is actually the worse deal per unit.

Frequently asked questions
What if the two products have different units (grams vs ml)?
Convert both to the same unit first, then enter the quantities — the calculator just needs matching units to compare fairly.
Does a bigger pack always win?
Not always — sometimes smaller packs are on sale and end up cheaper per unit. That is exactly why comparing unit price is useful.
Why do stores show unit price on shelf labels?
Many stores are required to display unit pricing so shoppers can compare value across different pack sizes and brands at a glance.
Can I compare more than two products at once?
This version compares two at a time — for more items, run the comparison in pairs, or note down each unit price and compare manually.
