About Online Unit Converter

Unit conversion comes up whenever you’re working across two different measurement systems — a recipe in metric units when you think in imperial, a spec sheet using units unfamiliar to your region, or simply needing an exact conversion rather than a rough mental estimate.

This tool covers the common conversion categories: length, weight, volume, and temperature, handling both the metric and imperial systems in both directions, so you can convert whichever direction you actually need without hunting for a specific converter for that one combination.

For cooking specifically, volume conversions (cups, tablespoons, milliliters) are usually more relevant than weight conversions, since most home recipes measure by volume — though professional and baking recipes increasingly specify weight (grams) for the added precision it gives, since a “cup” of a packed versus loosely-scooped ingredient can vary meaningfully.

Frequently Asked Questions

How do I convert units?

Choose a category tab, enter a value, then pick the From and To units. The result updates as you type. The six categories are length, weight, temperature, volume, area and speed, and everything is calculated in your browser.

How do I convert units of measurement by hand?

Multiply by the conversion factor between the two units. For example, miles to kilometres uses 1.609344, and pounds to kilograms uses 0.45359237. For temperature, use formulas instead: Fahrenheit equals Celsius times 9/5 plus 32. The converter applies these factors for you.

Which units can I convert?

Length: metres, kilometres, centimetres, millimetres, miles, yards, feet, inches and nautical miles. Weight: kilograms, grams, milligrams, pounds, ounces, stone and tonnes. Temperature: Celsius, Fahrenheit, Kelvin. It also covers volume (US units), area and speed.

Can I convert currency, time or data sizes?

No. This converter has six categories only: length, weight, temperature, volume, area and speed. It does not convert currency, time, data storage, pressure or energy, and its volume units are US measures, not UK imperial.
