For mainland China, a 斤 is 500g. Very common unit of weight.
Housing would be measured in 平米, square meters. It's pretty much impossible to understand that one as anything other than an adoption of the foreign norm. (Similarly for 斤, set at half a kilogram to fall within the range of traditional use while still fitting seamlessly into the metric system. But wholesale adoption there would mean measuring weights in 公斤, kilograms, which isn't done much.)
