How Price per Gram Calculator works
Compare products by price per gram and price per kilogram. Enter price and weight to normalise cost, which is how you spot a better deal on smaller packs. Everything happens inside this page: the tool reads your input, runs the calculation or conversion locally, and hands the result back to you. Nothing is transmitted, because there is no backend to transmit it to.
That design choice is deliberate. Most free tool sites upload your files to a server, process them there, and quietly keep a copy. Toolcin cannot do that — the site is a set of static files. If your connection dropped the moment the page finished loading, every tool would still work.
For anything sold by weight
Price divided by grams gives the unit cost; multiplying by 1,000 gives the price per kilogram, which is the number shops display. A 1,200 pack of 250 g is 4.80 per gram, or 4,800 per kg.
Four decimal places matter here — gold, spices and coffee all move in fractions of a unit, and rounding to two would hide the difference between suppliers.
Where this is used
Comparing packaged goods against loose weight, checking whether a bulk pack is genuinely cheaper, and pricing a product you resell by weight.
| Price | Weight | Per gram | Per kg |
|---|---|---|---|
| 1,200 | 250 g | 4.80 | 4,800 |
| 900 | 200 g | 4.50 | 4,500 |
| 450 | 100 g | 4.50 | 4,500 |
The packaging trap
The stated weight often includes packaging or is the drained weight rather than the total. For food in brine, compare the drained weight — a 400 g tin holding 240 g of produce is priced per 240 g, not 400.
