when did germany start using the metric system
Obsolete German units of measurement The metric system became compulsory on January 1, 1872, in Germany and on January 1, 1876, in Austria.[1]
Imperial units British law now defines each imperial unit in terms of the metric equivalent. The metric system is in official use within the United Kingdom for most official applications with Imperial units remaining in widespread use amongst the public.[36] All UK roads use the imperial system except for weight limits, and newer height or width restriction signs give metric alongside imperial.[37]
Measurement The metric system features a single base unit for many physical quantities. Other quantities are derived from the standard SI units. Multiples and fractions are expressed as powers of 10 of each unit. When smaller or larger units are more convenient for given use, metric prefixes can be added to the base unit to denote its multiple by a power of ten: a thousandth (10âˆ’3) of a metre is a millimetre, while a thousand (103) metres is a kilometre. Unit conversions are thus always simple, so that convenient magnitudes for measurements are achieved by simply moving the decimal place: 1.234 metres is 1234 millimetres or 0.001234 kilometres. The use of fractions, such as 2/5 of a metre, is not prohibited, but uncommon. There is no profusion of different units with different conversion factors as in the Imperial system which uses, for example, inches, feet, yards, fathoms, and rods for length.
Metric system In its modern form, it consists of a set of electromechanical base units including metre for length, kilogram for mass, second for time and ampere as an electrical unit, and a few others, which together with their derived units, can measure any useful quantity. Metric system may also refer to other systems of related base and derived units defined before the middle of the 20th century, some of which are still in limited use today.

Metrication in the United Kingdom Another example was the Met Office who, in 1962, started publishing temperatures in both Celsius and Fahrenheit, dropping the use of Fahrenheit from their official reports in 1970.[78]
