Perunit

Perunit tells you which pack is really cheaper. Enter the shelf price and the size of two to six items, and it works out the price per 100 g, per kg, per 100 ml, per litre or per item, highlights the cheapest and shows how much more each of the others costs in percent. Sizes can be in grams, kilograms, ounces, pounds, millilitres, litres, US fluid ounces or pieces, and they are converted so different units compare fairly: a 1 kg bag against an 18 oz box, or a litre bottle against a 500 ml one. Multipacks and deals are part of the sum. Enter "6 × 330 ml" as a pack of 6, and a "buy 2 get 1 free" offer spreads the price of two packs over three. • Compare 2 to 6 items side by side • Price per 100 g / kg, 100 ml / litre or per item • Metric and US units: g, kg, oz, lb, ml, L, fl oz, pieces • Multipacks and "buy N get M free" deals • Cheapest item highlighted, with the difference in percent • Save comparisons to check again on your next shop • Choose the currency symbol shown • Works offline, with no account and no ads Perunit only does the arithmetic: prices are the ones you type in, and it does not look anything up online.
