How to Use the Food Unit Price Comparator
When shopping for groceries, the same type of food often comes in different sizes and prices across brands. Looking at the sticker price alone can be misleading โ a larger package may seem expensive but actually costs less per gram. This tool calculates the price per 100g for up to 4 products and ranks them so you can instantly see which gives the best value.
Simply select how many products to compare, then enter the product name, price, and weight with its unit. The tool supports g, kg, ml, L, oz, and lb, so you can compare different packaging formats without manual conversion. For example, comparing a 32 oz box versus a 5 lb bag of flour becomes a one-click calculation.
Keep in mind that the lowest unit price is not always the smartest choice. Consider whether you can use a bulk package before it expires, and whether you have the storage space. If a product is on sale, enter the sale price to get the actual unit cost. Use this tool regularly to make informed grocery decisions and reduce your food spending over time.
