Unit Converter

Length, weight, temperature, area, volume and speed, across the metric and imperial systems — metres and feet, kilograms and pounds, Celsius and Fahrenheit, square metres and square feet, litres and US gallons, km/h and mph.

Most of the world quotes square metres; the United States quotes square feet, and Hong Kong quotes both. One square metre is about 10.76 square feet, so a "900 sq ft" flat and an "84 m²" flat are the same size. Convert before comparing rent per unit area between cities — otherwise the cheaper city can look like the more expensive one.
