英寸和脚的历史和起源

The inch and foot are units of length in the Imperial and United States customary systems of measurement that have a rich history dating back centuries. The word "inch" comes from the Latin word "uncia," meaning one-twelfth, as it was originally defined as 1/12 of a foot.

In early measurements, the inch was defined by the width of a human thumb. In fact, in many European languages, the word for "inch" is the same as or derived from the word for "thumb." By the 7th century, the inch was already being used in England, as referenced in the Laws of Æthelberht.

One historical definition of the inch from 1324, set by King Edward II of England, defined it as "three grains of barley, dry and round, placed end to end, lengthwise." Similarly, the foot was traditionally based on the length of a man's foot.

现代标准化

今天,一英寸和一英尺都被精确地用公分单位来定义. 自1959年通过国际院子和磅协议后,一英寸正等为25.4毫米,一英尺正等为0.3048米(或30.48厘米).

环绕世界的使用

虽然大多数国家已正式采用度量衡系统,但在美国,英国和加拿大,英寸和英尺仍然被普遍用于各种应用. 在英国,脚和英寸仍然用于人高和道路标志. 在全球范围内,英寸是测量显示屏(电视,显示器)和轮圈直径的标准.

标注和代表

Inches are commonly denoted by the symbol "in" or by a double prime (″). Feet are denoted by "ft" or a single prime ('). For example, 5 feet and 10 inches can be written as 5' 10″. In technical contexts, inches may be expressed in decimal form (e.g., 5.83 feet), but in everyday use, they're typically expressed as feet and inches.
