章節(jié)摘錄

版權頁：插圖：Measurement systems have been a necessity since people first began to build and barter, and everyancient culture developed some sort of measurement system to serve its needs. Standardization ofunits took place gradually over the centuries, often through royal edicts. Development of the BritishImperial System from earlier measurement standards began in the 13th century and was well estab-lished by the 18th century. The British system spread to many parts of the world, including the UnitedStates, through commerce and colonization. In the United States the system gradually evolved into theU.S. Customary System （USCS） that is in common use today.The concept of the metric system originated in France about 300 years ago and was formalized inthe 1790s, at the time of the French Revolution. France mandated the use of the metric system in 1840,and since then many other countries have done the same. In 1866 the United States Congress legalizedthe metric system without making it compulsory.A new system of units was created when the metric system underwent a major revision in the1950s. Officially adopted in 1960 and named the International System of Units （Systeme Interna-tional d'Unites）, this newer system is commonly referred to as SI. Although some SI units are thesame as in the old metric system, SI has many new features and simplifications. Thus, SI is animproved metric system.Length, time, mass, and force are the basic concepts of mechanics for which units of measurementare needed. However, only three of these quantities are independent since all four of them are relatedby Newton's second law of motion.
