Compare pack sizes to find the best value

How it works
To compare two packs, divide each price by its size. A 500 g pack at ₹120 costs ₹24 per 100 g. A 1 kg pack at ₹220 costs ₹22 per 100 g, so the bigger pack is cheaper. Enter up to three items, in grams, kilograms, millilitres, litres or pieces.
unit price = price ÷ size
We convert every item to the same unit first, so a pack in grams can be compared with one in kilograms.
Weight and volume can’t be compared directly, so we say so if you mix them.
Worked example. A 500 g pack at ₹120 is ₹24 per 100 g. A 1 kg pack at ₹220 is ₹22 per 100 g, so the bigger pack is cheaper here.
Examples
| Item | Price | Price per 100 g |
|---|---|---|
| 500 g pack | ₹120 | ₹24.00 |
| 1 kg pack | ₹220 | ₹22.00 |
| 250 g pack | ₹70 | ₹28.00 |
What this tool doesn’t cover
- This compares price only, not quality or how much you’ll use.
Questions
Is a bigger pack always cheaper?
No. Offers on small packs can beat large ones, which is why it’s worth checking.
Can I compare grams with millilitres?
No. They measure different things, so we won’t pick a winner.
What if I only fill in one item?
We show its unit price. You need two to compare.
How do I work out a unit price?
Divide the price by the amount. A 500 g pack at ₹120 costs ₹0.24 per gram, or ₹240 per kg.
Why should I compare unit prices?
Packs come in different sizes, so the sticker price can mislead. The unit price shows which one really costs less.
