The imperial gallon, and hence tne imperial pint, was established in 1824. The imperial gallon was defined as 10 pounds of water at 62� f. This was the British response to the metric system, and is the only factor of ten in the imperial system. Further standarization against the cubic decimetre was published in 1896.;The United Kingdom ratified the *Convention du M�tre* in 1884. I have not been able to find out what happened in 1878.
