What is Unit Converter?

A quick converter covering six everyday unit categories — length, weight, temperature, area, volume and speed — with metric units like kilometres, kilograms and Celsius front and centre alongside common imperial units.

How to use Unit Converter

Pick a category, enter a value, and choose the "from" and "to" units. The converted value updates immediately, and a swap button flips the two units.

Example

Converting 5 kilometres to miles gives approximately 3.11 miles; converting 30°C to Fahrenheit gives 86°F; converting 1 acre to square metres gives about 4,047 m².

Understanding your result

Length, weight, area, volume and speed conversions are exact multiplications between units. Temperature conversion uses the standard Celsius/Fahrenheit/Kelvin formulas rather than a simple ratio, since those scales do not share a zero point.
