How to use and verify
Enter the actual purchase price, quantity in one pack and number of packs. Total quantity equals quantity times pack count times the conversion factor. Kilograms become grams and liters become milliliters. Mass and volume cannot be mixed. For count-based products, check that the size and specification of each item are comparable.
Unit price is purchase price divided by total quantity, multiplied by 100 for mass or volume. Item prices use a base of one. Two 500 g bags costing 8000 have a price of 800 per 100 g; one 1 kg bag costing 7500 costs 750 per 100 g. Results sort from cheapest to most expensive, retaining input order for ties.
Use the same currency for every product. No exchange conversion is performed. Shipping and discounts are not estimated; include any relevant charges in the price you enter. Zero prices are allowed, quantities must be positive and pack counts must be positive integers.
Displayed rounding can make close values appear identical. Sorting uses unrounded values. Consider quality, expiry dates and usable quantity alongside this comparison and verify package labels before purchasing.
2026 example: 8000 ÷ (500 g × 2) × 100 = 800 / 100 g
