Metric System Day 2023: Metric System Day occurs annually on April 7. The metric system is now frequently used as a synonym for the International System of Units (or S.I.). It is a system of measurement used in most countries of the globe, excluding the United States and a few others. France introduced the metric system in 1799; it is a decimal-based (based on powers of 10) measurement system based on metres and kilogrammes. The metric system’s fundamental units are the kilogramme, the metre, and the litre. The metric system also measures temperature using the Kelvin scale (or the Celsius scale). In the metric system, the decimal-based prefixes include milli, centi, deci, and kilo. These prefixes are not, however, utilised with the temperature degree.
HISTORY OF METRIC SYSTEM DAY
The origins of the metric system date back to 1586, when the Flemish mathematician Simon Stevin published a pamphlet titled “De Thiende” (The Tenth). In the pamphlet, Stevin emphasised the significance of decimal measurement and predicted that decimals would one day be used as the standard unit of measurement worldwide. Well, Stevin’s prophecies did not come true until Napoleon became emperor of France and introduced the metric system in 1799, more than two centuries later. As Napoleon’s conquest of Europe progressed, he also implemented the metric system in his new territories. As soon as Napoleon was defeated at the Battle of Waterloo in 1815, France and the majority of his former colonies reverted to their previous systems of measurement. In 1837, France reinstituted the metric system, and in 1840, roughly 50 years after its introduction, the metric system was made mandatory throughout the country.
BACKGROUND
Other countries, including the newly-formed Kingdom of the Netherlands in 1815, adopted the metric system as a unified system of measurement in 1820. Likewise, the German Empire, which was constituted in 1871 from the former German Confederation, continued to use the metric system. In the same year, the newly unified Italy opted for the metric system over the previous systems of measurement. Other nations, including Brazil, Spain, Portugal, Norway, Mexico, Argentina, Peru, Colombia, Sweden, Denmark, Finland, Paraguay, Philippines, and Vietnam, adopted the metric system between 1875 and 1914. In 1866, the United States passed a law permitting commercial use of either the metric system or U.S. customary units. Many years later, in 1897, the United Kingdom also passed a law permitting its citizens to trade using either the metric system or Imperial units.
