What unit of measurement is used in USA?
The United States Code refers to these units as "traditional systems of weights and measures". Other common ways of referring to the system in the U.S. are: "Standard", "Customary", or, erroneously: "Imperial", or "English" (which refers to the pre-1824 reform measures used throughout the British Empire).
Most countries use the Metric System, which uses the measuring units such as meters and grams and adds prefixes like kilo, milli and centi to count orders of magnitude. In the United States, we use the older Imperial system, where things are measured in feet, inches and pounds.
- The metric system was first proposed in 1791. It was adopted by the French revolutionary assembly in 1795, and the first metric standards (a standard meter bar and kilogram bar) were adopted in 1799. There was considerable resistence to the system at first, and its use was not made compulsory in France until 1837.

The system of imperial units or the imperial system (also known as British Imperial or Exchequer Standards of 1825) 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.
10 milligrams (mg) = 1 centigram (cg) 10 grams = 1 dekagram (dag) 10 dekagrams = 1 hectogram (hg) = 100 grams 10 hectograms = 1 kilogram (kg) = 1,000 grams 1,000 kilograms = 1 metric ton (t)
- Three temperature scales are in common use in science and industry. Two of those scales are SI metric: The degree Celsius (°C) scale was devised by dividing the range of temperature between the freezing and boiling temperatures of pure water at standard atmospheric conditions (sea level pressure) into 100 equal parts.
- Since 1995, goods sold in Europe have had to be weighed or measured in metric, but the UK was temporarily allowed to continue using the imperial system. This opt-out was due to expire in 2009, with only pints of beer, milk and cider and miles and supposed to survive beyond the cut-off.
Up to and including the pound, the two systems are the same. The Americans never use the stone as a weight, which is in universal use in England (especially to weigh people). The hundredweight (cwt) in England is always 112 pounds, or 8 stone. In the US, the hundredweight is 100 lb, unless noted as otherwise.
- Lb is an abbreviation of the Latin word libra. The primary meaning of libra was balance or scales (as in the astrological sign), but it also stood for the ancient Roman unit of measure libra pondo, meaning “a pound by weight.”
- To work out your BMI:
- divide your weight in kilograms (kg) by your height in metres (m)
- then divide the answer by your height again to get your BMI.
- Simple steps to work out your imperial BMI:
- Multiply your height in inches (in) by itself.
- Divide your weight in pounds (lb) by your step 1 result.
- Multiply the result from step 2 by 703.
