Frequently asked questions
How many cft are in one brass?
One brass is 100 cubic feet, which is about 2.83 cubic metres. It's commonly used for sand, aggregate and excavation in western and central India.
Is a bigha the same in every state?
No. The size of a bigha (and of a katha) differs between states and even districts. The converter uses the Assam and West Bengal bigha of 14,400 sq ft, and lists the West Bengal (720 sq ft) and Assam (2,880 sq ft) katha separately.
