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
- Enter the price for Product A and Product B.
- Enter quantity for each product and choose the unit.
- Check each product's unit price and normalized unit price.
- 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.
