About Convierte

Convierte is a free set of everyday conversion tools built to do one thing well: give you an accurate answer in seconds, without clutter, pop-ups, or sign-ups. Whether you are buying shoes from a foreign retailer, following a recipe written in cups when your scale reads grams, or counting down to a holiday, the goal is the same — a clear result you can trust.

The site is fully bilingual (English and Spanish) from the first page to the last, with content written for real people rather than machine-translated. Every tool runs entirely in your browser: the maths happens on your device, nothing is sent to a server, and there is no account to create.

What you will find here

Three tool families cover the conversions people search for most. The shoe and clothing size converters translate between US, EU, UK, Japanese, Korean and international sizing for men, women and children. The cooking converter turns grams into cups (and back) for more than a hundred everyday baking ingredients, each with its own measured density. The countdown tools show exactly how many days remain until popular holidays and events.

Each page pairs an interactive calculator with a full, printable reference table, so the information is useful whether you want a single quick answer or the complete chart.

Our commitment to accuracy

Sizes and densities come from recognised references — foot-length charts for footwear, standard apparel size tables, and the USDA FoodData Central database for ingredient densities. Where a value is an industry estimate rather than an official figure, we label it honestly. If you ever spot a number that looks wrong, please tell us; corrections are welcome and we act on them.
