Online unit converter for length, weight, volume and temperature

The online unit converter is ideal when you need to quickly switch between metric and imperial systems. Convert cm to inches, meters to feet, kilometers to miles or even nautical miles for mapping and travel. For weight you can go from kg to lbs or stone to kg, and for volume you can convert liters to US gallons and US dry cups to milliliters.

The temperature section supports Celsius to Fahrenheit and back, which is useful when reading documentation, recipes or scientific articles written in a different standard. Keep this page pinned and use it as a simple calculator whenever you are working with measurements in code, design specs or real‑world projects.

How to get accurate results

Enter a value, choose the source and target units, and click Convert. The calculator normalizes everything internally (meters for length, kilograms for weight, liters for volume), then converts to your chosen target unit. This approach reduces rounding issues so that repeated conversions remain consistent.
