Unit conversion and measurement tools
Conversion Tools
Convert measurements, sizes, and units between international systems with our free conversion tools. Whether you're shopping from an overseas store and need to translate shoe sizes, converting recipe measurements between metric and imperial, or looking up how many grams are in a cup of flour — these converters give you instant, reliable results.
Our conversion tools are designed for practical, real-world scenarios — not just abstract unit math. Each tool includes reference tables, step-by-step guides, and supports multiple international standards.
Shoe Size Converters
We offer four shoe size converters to cover every common conversion need. The general shoe size converter translates between all 8 international sizing systems at once: US, UK, EU, JP (Japan), KR (Korea), BR (Brazil), MX (Mexico), and AU (Australia). Select men's, women's, or kids' sizes and get instant results across all systems.
For quicker pair-to-pair lookups, use the dedicated converters: the US to EU shoe size converter, the US to UK shoe size converter, and the EU to UK shoe size converter. Each one focuses on a single pair of systems with a streamlined interface and a complete size chart for that combination.
Enter any known size or your foot length in centimeters to see the equivalent in the target system. A full reference table shows all conversions at a glance, and the built-in foot measurement guide helps you find your exact size if you're unsure.
Cooking Converters
Our cooking conversion tools help you follow recipes accurately regardless of which measurement system they use. The cooking converter is the all-in-one tool for converting volumes, weights, and temperatures between metric and imperial — tablespoons to milliliters, ounces to grams, Fahrenheit to Celsius, and more.
For the most searched cooking conversions, we also offer dedicated tools. The cups to grams converter handles ingredient-specific conversions, since a cup of flour weighs very differently from a cup of sugar or honey. The tablespoons to ml converter is ideal when scaling recipes or using a European recipe with US measuring spoons. The oz to grams converter lets you switch between imperial and metric weight in seconds.
All cooking converters include ingredient-specific data and practical examples so you get results that match real cooking — not just theoretical unit math.
Accurate, Practical Conversions
Our converters use lookup tables from industry standards rather than approximate formulas. This means the results match what you'll actually find in stores or in practice, not theoretical calculations that may differ from real-world values.
Every conversion tool includes a disclaimer where relevant, because standards can vary between brands and manufacturers. We aim to give you the most reliable starting point so you can shop and convert with confidence.
Frequently Asked Questions
Use the general shoe size converter to see your size across all 8 international systems (US, UK, EU, JP, KR, BR, MX, AU) at once. For a faster lookup between two specific systems, use one of the dedicated converters: US to EU, US to UK, or EU to UK. You can also enter your foot length in centimeters for the most accurate conversion.
The number of grams in a cup depends on the ingredient. A cup of all-purpose flour weighs about 120–130 g, a cup of granulated sugar about 200 g, a cup of butter about 227 g, and a cup of water or milk about 240 g. Use the cups to grams converter to get accurate weights for dozens of common ingredients.
One US tablespoon equals 14.79 ml (commonly rounded to 15 ml). One UK tablespoon equals 17.76 ml. Use the tablespoons to ml converter for quick and precise conversions when scaling recipes.
One ounce equals 28.35 grams. To convert, multiply the number of ounces by 28.35. For example, 4 oz = 113.4 g. Use the oz to grams converter for instant, accurate results without manual calculation.
Shoe size conversions are standardized but can vary slightly between brands. Our converters use industry-standard lookup tables for the most accurate results. We recommend checking the specific brand's size chart when ordering, especially for the first time.
