Price-Per-Unit Comparator
Enter multiple products with their package price, size, and unit to see prices normalized to a common measure. Supports weight (oz, lb, g, kg), volume (fl oz, mL, L, gal), and count comparisons. The tool highlights the best value, shows savings versus the most expensive option, and charts unit prices for visual comparison. Use it for shelf-tag audits, competitive pricing, or everyday shopping math. Runs entirely in your browser — your data never leaves your machine.

Why Unit Price Matters
Package prices are misleading when sizes vary. A 24-oz jar at $4.99 looks cheaper than a 5-lb bag at $12.99, but per-ounce the bag costs roughly half as much. Unit pricing strips away the packaging and shows the true cost of what you’re buying. Retailers are required to display unit prices on shelf tags in many jurisdictions, and buyers and category managers use unit cost analysis to evaluate vendor bids, set competitive prices, and flag margin-eroding SKUs.
Common Unit Conversions in Grocery
This tool converts across standard measurement systems: weight (ounces, pounds, grams, kilograms), volume (fluid ounces, milliliters, liters, gallons), and simple count. It uses NIST standard conversion factors. The tool auto-detects the unit group from your first entry and normalizes all items to a common base, which you can override with the “Compare per” selector.
Automating Price Analysis
For bulk competitive analysis across thousands of items, I build pricing intelligence tools that pull data from your merchandising systems and vendor catalogs. See grocery and retail services or explore custom reporting. Also see the Margin & Markup Calculator for pricing math.
