What Is a Price Per Unit Calculator?
A Price Per Unit Calculator divides the total price of a product by its quantity to give you the cost for a single unit. This makes it easy to compare different pack sizes or suppliers — a 500g pack for ₹80 vs a 1kg pack for ₹145 looks cheaper at first, but the per-unit price reveals which is actually better value. The Compare mode lets you evaluate up to 3 products simultaneously, highlighting the cheapest per-unit option automatically.
