Fahrenheit is a scale for measuring how hot or cold something is. On this scale, water freezes at 32 degrees and boils at 212 degrees. We write the unit as °F. A healthy human body is about 98.6°F.

Fahrenheit華氏 is a scale for measuring how hot or cold something is是用來量東西有多熱或多冷的一種溫標。On this scale在這個溫標上 water freezes at 32 degrees水在32度結冰 and boils at 212 degrees在212度沸騰。We write the unit as °F這個單位寫成 °F。A healthy human body健康的人體體溫 is about 98.6°F大約是98.6°F。

The United States still uses Fahrenheit for weather, cooking, and fever; Taiwan and most of the world use Celsius instead. So the number you hear matters only if you know which scale is speaking. 77°F is a nice day. 77°C would be dangerously hot air.

The United States still uses Fahrenheit美國在天氣、烹飪和發燒體溫上還是用華氏 for weather, cooking, and fever Taiwan and most of the world use Celsius instead而台灣和世界上大多數地方用的是攝氏。So the number you hear matters only if you know which scale is speaking所以聽到的數字，要先知道是哪個溫標才有意義。77°F is a nice day 77°F是舒服的好天氣。77°C would be dangerously hot air77°C可就是危險的高溫了。

The name comes from Daniel Gabriel Fahrenheit, a Prussian scientist, who built thermometers and set this scale. He chose his numbers from very cold mixtures and from body heat, and later the freeze-and-boil points were fixed at 32 and 212 so the gap would be a round 180 degrees. The first laboratory choices are a little tangled in the history, so remember the water numbers; they will not let you down.

The name comes from Daniel Gabriel Fahrenheit這個名字來自丹尼爾．加百列．華倫海特 a Prussian scientist一位普魯士科學家 who built thermometers and set this scale他製作溫度計並訂出這套溫標。He chose his numbers from very cold mixtures and from body heat他當初的數字來自非常冷的混合物和體溫 and later the freeze-and-boil points were fixed at 32 and 212後來結冰點和沸點固定在32度和212度 so the gap would be a round 180 degrees讓中間剛好差180度整。The first laboratory choices are a little tangled in the history最早實驗室裡的選擇在歷史上有點說不清楚 so remember the water numbers所以只要記住水的那兩個數字就好 they will not let you down它們不會讓你出錯。
