What is Imperial: Definition and 58 Discussions

The imperial system of units, imperial system or imperial units (also known as British Imperial or Exchequer Standards of 1826) is the system of units first defined in the British Weights and Measures Act 1824 and continued to be developed through a series of Weights and Measures Acts and amendments. The imperial units replaced the Winchester Standards, which were in effect from 1588 to 1825. The system came into official use across the British Empire in 1826. By the late 20th century, most nations of the former empire had officially adopted the metric system as their main system of measurement, but imperial units are still used in the United Kingdom and some other countries formerly part of the British Empire. The imperial system developed from what were first known as English units, as did the related system of United States customary units.
The modern legislation defining the imperial system of units is given in the Weights and Measures Act 1985 (as amended).

    How Can I Refresh My Knowledge of Physics?

    Hi, I love physics since school, but after years I forgot a lot of what I studied. I hope this forum will help refresh my memory. Also I built a web converter application to convert different measurement units and this forum can be really helpful for me to promote it and keep improving it. Thanks
