“Metric Units. – The Meteorological Office, under the direction of Sir Napier Shaw, has introduced a new system of units for the official records of British Meteorology based on absolute measures and the metric system. … I should not have felt justified this year undertaking the expense of converting over 5000 values from inches to millimetres (an operation which had to be done twice over to ensure accuracy), and of altering the format of the volume by widening the page to admit the additional column; but on explaining the position to Sir Napier Shaw I had the satisfaction of finding that the Meteorological Office was prepared to assist by bearing the cost of the change, which amounted to £30.”

Commentary on the change to metric units introduced in the Met Office over a century ago, by Hugh Robert Mill, director of the British Rainfall Organization, British Rainfall 1914 (British Rainfall Organization 1915)
