为什么一英里等于5280英尺？
[ 20060825 11:39 ]
从古到今，世界上出现过很多种度量方法。英里是其中的一个度量单位。不过奇怪的一点是，一般的度量单位是以整数进位的，英里却不同。一英里等于5280英尺，而非5000英尺或是6000英尺。原来，这是英国度量单位与罗马度量单位妥协的结果。欲知详情如何，且看下文分解。
The measurement known as a mile is avestigeof the Roman Empire's rule over Britain. At this time, the Romans had a measurement known as mille pasuum (MElay PAsooem), or a thousand paces. A pace comprised five, possibly sandal shod, Roman feet. Using a simple mathematical calculation, we arrive at 5,000 feet per mile.
Thedemiseof the Roman Empire left the Britons in aquandary. They now had a mile, consisting of 5,000 feet, and their own agricultural measurement, thefurlong, used to measure the farmers' fields for the purpose of property deeds, etc. Instead of using the Roman foot in calculating the measure of a furlong, they used the distance a horse could pull a plow, in a linear fashion, before thenagneeded anap. They agreed that this measurement consisted 660 feet.
Now came the dilemma. The British wished to marry the furlong to the mile, but, as they wanted a mile to comprise eight furlongs, totaling 5,280 feet, instead of the Roman 5,000 feet per mile, they had no choice but to select one of the two. Not surprisingly, they chose their measurement over the Roman measurement because, as property deeds at the time were measured in furlongs, or 660 feet, a change to the Roman measurement would short the farmer or landowner.
