Conversion Tools
Convert measurements, sizes, units, and calendar dates 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, looking up how many grams are in a cup of flour, or converting a Thai Buddhist Era date for a visa application — 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.
Calendar Converters
The Buddhist calendar converter translates dates between the Thai Buddhist Era (BE / พ.ศ.) and the Gregorian calendar (CE) in both directions. The rule is simple: BE = CE + 543. Enter a full date in either system and instantly see the equivalent date, the day of the week, the date in Thai numerals, and the ISO-8601 format for use in spreadsheets and international paperwork.
This tool is especially useful for expats living in Thailand, travelers applying for Thai visas, lawyers and real-estate professionals reading Thai contracts and land title deeds, and anyone who needs to interpret dates on Thai government documents, national ID cards, or official certificates. The converter also handles the historical pre-1941 calendar reform correctly — dates in January, February, and March before BE 2484 use an offset of 542 instead of 543.
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.
