Overview

The Unit Price Comparison Calculator helps you compare two products by per-unit cost under the same unit type. Enter price, quantity, and unit, and the tool converts units automatically to show which option offers better value.

Key Features

• Compare two products with real-time price, quantity, and unit input.
• Convert units such as g/kg, ml/L, and meter, then display normalized unit prices.
• Show the better-value product, price difference, and cheaper percentage.
• Detect non-comparable unit types (for example, mass vs volume) and provide guidance.

How To Use

1. Enter the price for Product A and Product B.
2. Enter quantity for each product and choose the unit.
3. Check each product's unit price and normalized unit price.
4. Use the comparison conclusion, difference, and hint to make a buying decision.

Formula

• Unit price = total price / quantity
• Normalized unit price = unit price / unit conversion factor
• Difference = |normalized unit price of A - normalized unit price of B|
• Cheaper percentage = difference / max(normalized unit price of A, normalized unit price of B) x 100%

FAQ

• Can I compare grams and kilograms directly? Yes. The tool normalizes both to the same base unit.
• Can I compare grams and milliliters directly? No. They are different unit categories unless density conversion is provided.
• Is data uploaded? No. All calculations run locally in your browser.
