About Unit Converter
Unit conversions come up constantly — centimeters to inches, kilograms to pounds, Celsius to Fahrenheit, liters to gallons, megabytes to gigabytes. This converter handles length, weight, temperature, volume, area, speed, and data storage units all in one place, showing results across all units simultaneously so you can pick whichever one you need.
It also handles the conversions that trip people up between Europe and the US: tyre pressure (psi ↔ bar), engine power (hp ↔ kW ↔ metric PS), fuel economy (US mpg ↔ UK mpg ↔ L/100km), and US vs UK gallons and pints. Type a value in any field and all others update instantly — no need to remember formulas or switch calculators. Great for cooking with international recipes, car specs, shopping from overseas stores, travel, and science or engineering work.
