What your readers get

The same calculator as on this site: enter a price and package size for one or more products and see the price per ounce, pound, kilogram, 100 g or liter, plus which one is cheaper and by how much. It handles mixed units (grams against ounces), multipacks and count items.

Everything is calculated in the reader’s browser. Nothing they type is sent anywhere, and the widget shows no ads.

How to add it

Pick the options above, press Copy code and paste the snippet into your page’s HTML (in WordPress, use a Custom HTML block). The widget is 100% wide up to 480 pixels, so it fits a phone screen and a blog column alike.

Please keep the short credit line under the iframe. It is how readers can find the full calculator, and it is the only thing we ask in return.
