In he wrote in his log book a wind force scale. The scale was simple and very similar to one that Alexander Dalrymple had written in a book in A year later he added some criteria to the scale that indicated how much of a ship's sails would be employed by a British man-of-war under each condition. It was not related to the speed of the wind.
Over the following years he continued to use his scale in his logs. However, as ship design and the introduction of steam power became widespread even that scale had to be modified.
In the International Commission for Weather Telegraphy sought some agreement on velocity equivalents for the Beaufort scale. A uniform set of equivalents was accepted in and revised slightly in , extending the scale to 17 values the added five values further refining the hurricane-force winds. By , wind velocities in knots replaced Beaufort numbers on weather maps. The car consumes an average of 1 liter of fuel for every 4 kilometers.
