How it works

Floor plans in square metres, listings in square feet, land in acres. This puts all of them in one place, including the survey units that show up on deeds and the odd Chinese and Japanese measures that appear in property listings.

The formula

Every unit is defined by how many base units it is worth, so the conversion is value x factor(from) / factor(to).
