Grocery Unit Pricing Principles

1. Beware the "Package Size Illusion"

A ₹90 pack is not cheaper than a ₹120 pack if the first has 300g (₹300/kg) and the second has 500g (₹240/kg). Always normalize to cost per 100g or 1 kg before deciding.

2. Weight and Volume Cannot Cross-Convert

1 litre of milk is not 1 kilogram. Oil is even lighter (~910g per litre). This calculator strictly preserves physical dimensions to prevent dangerous billing errors.

3. Budget Scaling vs. Fixed Quantity

When shopping at fresh sabzi mandis, buying to an exact note (e.g. ₹50 or ₹100) avoids awkward coin change. Use Mode 2 to know the exact weight the vendor should weigh.

Value Theorem

Package Normalization Architecture

True Value Definition:

Real grocery savings come from minimizing the unit price (₹/kg or ₹/100g), not from choosing the lowest upfront package price.

Understanding Grocery Unit Pricing

Whether you are buying 750 grams of vegetables quoted per kilogram or 500 millilitres of milk quoted per litre, normalizing to unit cost guarantees you never overpay.
