Some of the most profound statements on the nature of science have come from Albert Einstein, one of the greatest scientists of all time. . The Imperial units or the Imperial system is a collection of measurement units. The SI was established in 1960 and is based on the metre-kilogram-second system rather than the centimetre-gram-second system. In keeping with the Omnibus Trade and Competitiveness Act of 1988, the ultimate objective is to make the International System of Units the primary measurement system used in the United States. Most countries use the International System of Units ().In contrast, the furlong/firkin/fortnight system of units of measurement draws attention by being extremely old fashioned and off-beat at the same time.. One furlong per fortnight is very nearly 1 centimetre per minute (to within 1 part in 400).

SI units (International System of Units) Metric system; For example, SI unit of length is a metre (m), while metric units are kilometre (km), meter (m), decimetre (dm), centimetre (cm) and millimetre (mm). Background Definitions of the SI base units and their historical context International aspects of the SI Unit conversions. Among the SI base units, the kilogram (kg) is the only one whose name and symbol, for historical reasons, include a prefix. Names and symbols for decimal multiples and submultiples of the unit of mass are formed by attaching prefix names to the unit name "gram," and prefix symbols to the unit symbol "g." There are four types of speed: uniform speed, variable speed, average speed, and instantaneous speed. The International System of Units (abbreviated as SI Units from its French name, Système International d'unités) is an internationally agreed metric system of units of measurement that has been in existence since 1960. .
