Of course, in addition to domestic, joint venture vehicles, there are a considerable number of imported cars, and even non Chinese specifications of the models are also occupying people's line of sight. In order to buy a car, compared to the previous us to pick and choose, but in contrast to several cars, but often found that data specifications of each car, are not unified. If it were made in China, it would be better. If there are domestic cars and imported cars, then the metric and British data are really a big headache. After a period of comparison and summary, the editor will write some rules and some quick conversion methods between the public and the British, hoping to help you buy your car later.Length: the average import car likes to use length (feet) and inches (inch, usually abbreviated in.) to indicate length, then it is converted to metric:1 inches (in.) =2.54 cm, 1 feet (feet) =12 inches, =30.48 cm, 1 yards (yard) =3 feet, =0.9144 metersIn the distance, they prefer to travel miles rather than kilometers.1 miles, =1760 yards, =1.61 kilometersIt is advisable to use 1 miles =1.6 kilometers when using Volume: imported cars in the trunk volume, tank volume and soon, love with cubic feet (usually indicated by the abbreviation cu.ft.), gallons (usually indicated by the abbreviation Gal.) and other units, and we used the "rise" of this unit.1 cubic feet (cu.ft.) =28.317 liters,1 cubic meters =35.3147 cubic feet.Gallon into British US gallons and gallons:1 imperial gallon =4.546 liters,1 US gallons =3.785 litersIn addition, some American car manufacturers are accustomed to using cubic inches (cu.in.) to indicate engine displacement.1 cubic inches (cu.in.) =16.317 cubic centimeters =16.317 ml.Weight: the weight of imported cars, more accustomed to using "pounds" to say, generally "pound" is divided into "long imperial pounds" system and "two pounds short", is now more long pounds (usually indicated by the abbreviation lb.)1 pounds (lb.) =0.4536 kgIn the calculation, general 1 pounds long =0.454 kg, if in vehicles without a calculator, so you can compare the vehicle weight (pounds) * 0.9, then by 2 to obtain the approximate number of kilograms (error of 0.8%). For example, a SUV can pull 5000 pounds of trailers, then 5000 * 0.9=4500 (Shi Jin), 4500divided by 2, that is 2250 kilograms.Power: in Europe and the United States, "horsepower" (that is, horsepower, usually abbreviated HP), this unit is still widely used. Horsepower according to the current scope, and can be divided into British horsepower and metric horsepower, while the international standard used to measure the "kilowatt" to measure the power of the engine.1 imperial horsepower, =0.746 kW 1, metric horsepower =0.7355 kwGeneral metric horsepower conversion, you can take 1 metric horsepower =0.735 kW, 1 kW =1.36 horsepower.In addition by the above two equations we can see that the imperial horsepower than metric horsepower "worth", which is why the same numerical car with imperial horsepower show, than small reasons for metric horsepower show. A 147 kilowatt car, for example, should be 200 metric horsepower, but only 197 horsepower when performed in Imperial horsepower. However, in view of the relatively close numerical values, they are usually not specified at the time of conversion,Approximately 1 British horsepower =1 metric horsepower.Torque: relative to cattle, meters, European and American countries prefer to use the pound foot (usually abbreviated ft-lb, or lb.-ft) to indicate the torque of the automobile engine. If it is not a special understanding of the two units, the conversion will be more troublesome, the editor providesa simple algorithm:1 pounds, ft-lb, =1.355 ox, MFor example, TOYOTA Sequoia Limited's 4.7 liter engine torque is 314 pounds, feet, then converted to metric is 425.47 cattle meters.Fuel consumption: compared to L/100KM in our country and other countries, there is another fuel consumption algorithm that occupies half of the country: MPG, that is, miles per gallon per gallon of gasoline. Simply according to each of these English units to convert to L/100KM is more troublesome, editors recommend a relatively fast method.If it's 1 miles per gallon, then..:L/100KM=282.35/MPG numberFor example, a car every 1 gallons to 25 miles, or MPG=25, then divide 282.35 by 25, equal to 11.294, then it is converted into a 11.294 liter /100KM L/100KM.If every 1 miles to the gallon, so:L/100KM=235/MPG numberFor example, a car every 1 US gallon can run 25 miles, namely MPG=25, then with 235 divided by 25 is equal to 9.4, then it is converted into a 9.4 liter /100KM L/100KM.。

system) was adopted in 1960 by the 11th General Conference on Weights and Measures. An expanded and modified version of the metric system, the International System addresses the needs of modern science for additional and more accurate units of measurement. The key features of the International System are decimalization, a system of prefixes, and a standard defined in terms of an invariable physical measure. 国际制度（国际制度的缩写为SI，是国际制度的法语名称）被1960年的第十一届大会用于度量衡。

Not just a unit, but a comment that the number represents a difference between two pressures. PSID gauges have two input connectors. PSIA is PSID relative to vacuum, PSIG is PSID relative to local atmospheric pressure, and PSIS is PSID relative to a sealed 14.7-psi pressure vessel.PSI = Pound per Square Inch (磅/每平方英吋) PSID == PSI Differential (PSI 压差).PSIA == PSID to Vacuum (对真空的压差)PSIG == PSID to environment (对表外环境的压差)工作压力10-40PSID 表示仪器能承受10-40PSI 的压力差.温度的测算标准有两种：摄氏和华氏。

当然，除了国产、合资车以外，还有相当部分的进口车、甚至是非中国规格的车型也在侵占着人们的视线。
为了买一辆好车，之前我们总要挑三拣四的对比一下，但是在对比几辆车时，却往往发现每个车的数据规格，都不是统一的。
如果都是国产车，尚能好一点。
如果这其中又有国产车，又有进口车，那么公制和英制的数据真是让我们大伤脑筋。
编辑经过一段时间的对比、总结后，将公、英制之间的一些换算规则及某些快速换算办法写出来，希望能对您以后的买车有所帮助。
长度：一般进口车都喜欢用英尺（feet）、英寸（inch，一般用缩写in.来表示）来表明长度，那么它与公制的换算是这样的：1英寸（in.）=2.54厘米， 1英尺（feet ）=12英寸=30.48厘米 1码（yard）=3英尺=0.9144米距离方面，他们多喜欢用英里而非公里。
1英里=1760码=1.61公里使用的时候可取1英里=1.6公里体积：进口车在行李箱容积、油箱容积等方面，喜欢用立方英尺（一般用缩写cu.ft.来表示）、加仑（一般用缩写gal.来表示）等单位，而我们习惯了用“升”这个单位。
1立方英尺（cu.ft.）=28.317升，1立方米=35.3147立方英尺。
加仑分为英制加仑和美制加仑：1英制加仑=4.546升，1美制加仑=3.785升另外，有的美国汽车厂商，在表明发动机排量时习惯用立方英寸（cu.in.）来表示。
1立方英寸（cu.in.）=16.317立方厘米=16.317毫升重量：重量方面，进口车多习惯用“磅”来表示，一般来说“磅”又分为英制的“长磅”和美制的“短磅”两种，现在较多的是使用长磅（一般用缩写lb.来表示）1长磅（lb.）=0.4536千克在计算时，一般可取1长磅=0.454千克，如果在比较车辆时身边没有计算器，那么可以将比较车辆的车重（磅数）×0.9，然后再除以2即得到近似公斤数（误差在0.8%）。
例如一辆SUV可牵引5000磅的拖车，那么5000×0.9=4500（市斤），4500再除以2，就是2250公斤了。
