美國佬禍害世界最大的就是英製度量,記得動畫片the simpsons有一隻,Simpson就唱,we ruin the world by inches

華氏溫度和攝氏溫度重合在零下40度。兩者換算公式是 F = C * 9/5 + 32。若 F 和 C 都等於 -40,則等式成立。
實際上,華氏比攝氏的有點還有幾個。
1.華氏1度相當於攝氏5/9度,所以若隻用整數,可以比攝氏表達的溫度更精確。這個有點可比厘米較英寸的優點。
2.水的沸點和冰點(攝氏的100度和0度)並非不變的常量。珠穆朗瑪峰上,水70攝氏度就沸騰了。潛艇螺旋槳葉片上,由於葉片旋轉造成的低壓,常溫下,水就沸騰了(這是潛艇噪音的最大來源)。可是華氏100度,最初是人的體溫(當然有些誤差)。人的體溫,隻要還活著,基本上是恒定的,無論是高空還是海底。即使發燒,也差不了幾度。這就比水的沸點,穩定多了。
3.再有就是樓主說的感受。100華氏度,對人來說很熱。0華氏度,對人來說很冷。用起來很方便。
It's all arbitrary things, metrics or English measurements. The only difference is whether most people accept it. There's nothing wrong with using Fahrenheit instead of Celsius if most people like it or are used to it. The majority of Americans are not used to the metric system, sudden conversion will cause confusion in many aspects. So yeah, without consensus from the majority population, forget about it. Fahrenheit is just fine for me, after 20+ years of living with it.
