Imperial Units

The system of imperial units or the imperial system (also known as British Imperial) is the system of units first defined in the British Weights and Measures Act of 1824, which was later refined and reduced. The system came into official use across the British Empire. By the late 20th century, most nations of the former empire had officially adopted the metric system as their main system of measurement, although as of 2012 the United Kingdom had only partially adopted it.

Famous quotes containing the words imperial and/or units:

    Fair tresses man’s imperial race ensnare,
    And beauty draws us with a single hair.
    Alexander Pope (1688–1744)

    Even in harmonious families there is this double life: the group life, which is the one we can observe in our neighbour’s household, and, underneath, another—secret and passionate and intense—which is the real life that stamps the faces and gives character to the voices of our friends. Always in his mind each member of these social units is escaping, running away, trying to break the net which circumstances and his own affections have woven about him.
    Willa Cather (1873–1947)
