Are BA Screws Metric or Imperial?

The truth about Metric BA threads.
www.stubmandrel.co.uk www.stubmandrel.co.uk
"So, the list of BA thread sizes is reached on the basis of a list of sizes, each 0.9 times the size of the previous, starting at 6.00 millimetres. This list is then rounded to the nearest hundredth of a millimetre, equivalents in 'mils' or thousandths of an inch are approximate. We have to face the truth, British Association threads are well and truly metric."
