美国人为什么还在用华氏度

2018.08.22 英语麦克风 为什么美国人还在用华氏度 Students have to train for two sets of measurements, making science education even more difficult. And companies spend extra dollars producing two sets of products, one for the US and the other for metric. There’s also an argument for public health. According to the CDC, about 3 to 4 thousand kids are brought to the ER, due to unintentional medication overdose every year. And conversion errors for dosage are to blame. So, it seems like a no-brainer - America needs to switch to the metric system to match the rest of the world. But it is still struggling to make that change. That’s because it’ll take a lot of time and money but there’s no financial proof that this will all be worth it. So, unless that change is proven to be economically better, we’re not going to be using Celsius anytime soon. 学生们必须要接受（公制和美制单位）两套测量方法的学习，这使科学教育更加困难。此外，商家要花费额外的美金来生产两套产品，一套是给美国人用，另外一套是给使用公制单位的人用。甚至还对公共卫生产生了争论。根据疾病防控中心显示，每年有三千到四千名儿童由于无意识地过量用药而进了急救室。罪魁祸首是剂量单位转换错误。 所以，显而易见——美国需要改用公制，以便和世界上其他国家匹配。但是美国至今仍在纠结这一问题。因为这一改变将会花费大量的时间和金钱，而且，目前经济上没有证明这样做是值得的。所以，除非这种改变被证明能让经济变得更好，否则短期内我们不会使用摄氏度。
