Abstract
THE torr has recently been adopted as the British standard unit for the measurement of pressure in vacuum physics; but the fact that proposals have been made for further change1,2 indicates that the present system is not yet satisfactory. The recent proposals have been concerned with definition of units; but the practical expression of pressures in terms of these units appears also to be due for revision.
