Hey ,
Do you ever find yourself standing in a store aisle, trying to do mental math to figure out which item is the actual best value? Like, is the 48 oz giant bottle of olive oil a better deal per ounce than the 1-liter bottle next to it?
I run into this all the time, and the unit conversions are a pain. To solve this, I built a simple, free web tool to do the math for you: Unit Price Comparator.
Here’s how it works:
You add a card for each product you want to compare.
Enter the price, quantity, and unit for each one.
The key feature is that it automatically handles different units. You can directly compare a 2 lb bag against a 900g bag, or a gallon of milk against a 2-liter carton. It supports common weight (oz, lb, g, kg) and volume (fl oz, gal, l, ml) units.
It instantly calculates the price per common unit and highlights the “Best Deal!” so you know which one to grab.
It’s designed to be fast and easy to use on your phone while you’re shopping.
Is this something you could see yourself using?
Are there any features or units you think are missing that would make it more helpful?
I’d love to hear what you think. Thanks for checking it out!
