华氏与摄氏换算公式,华氏摄氏体温换算表

A hot day means something very different temperature-wise in Fahrenheit and Celsius.

炎热的一天指的是华氏温度和摄氏温度非常不同的温度。

Depending on where you live in the world, you either use the Fahrenheit or the Celsius temperature scale. Converting between the two is easier than you may expect. A couple of simple formulas can help you estimate or exactly convert between the temperature scales.

依据你生活所处的地方，你可以使用华氏温标或摄氏温标。两者之间的转换比您想象的要容易。几个简单的公式可以帮助您估计或准确地转换温度尺度。

If you're living in the United States, you're probably accustomed to reading temperatures in Fahrenheit. On a summer day with the sun beating down on you, it may feel like almost 100 degrees, while a winter day may feel closer to 40 degrees. Yet, if you were living in almost any other country in the world, you're likely used to reading temperatures in Celsius. In this case, 40 degrees describes a hot summer day, while zero degrees would be more typical of a winter day.

如果你生活在美国，你可能已经习惯了用华氏温度来读取温度。在夏天，太阳直射在你身上，感觉温度接近100华氏度，而冬天可能感觉接近40华氏度。然而，如果你生活在世界上几乎任何其他国家，你可能都习惯用摄氏度来读取温度。在这种情况下，40度描述的是炎热的夏天，而0度更典型的是冬天。

The Fahrenheit scale was created by Daniel Gabriel Fahrenheit in 1724. He originally created the scale to measure temperature using mercury thermometers, which he also invented. The Celsius scale was created by Anders Celsius in 1742. But when the scale was first introduced, Celsius used the reverse of today's scale. He labeled 0 as the boiling point of water and 100 as the freezing point. After Celsius' death, Swedish taxonomist Carl Linnaeus flipped the Celsius scale into what it is today, making 100 represent boiling temperature and 0 as the freezing point.

华氏温标是丹尼尔·加布里埃尔·华氏在1724年发明的。他最初发明了水银温度计来测量温度，水银温度计也是他发明的。摄氏温标是由Anders Celsius在1742年发明的。但是当温度计首次被引入时，摄氏度使用的是与今天相反的刻度。他把0标为水的沸点，100标为冰点。在Anders Celsius死后，瑞典分类学家卡尔·林奈将摄氏温标改为今天的温度，100代表沸点，0代表冰点。

This formula will help you make a close estimate for a Fahrenheit temperature when you're converting from Celsius. This is a great formula to do quickly in your head. Simply multiply the Celsius temperature by 2 and add 30 to it:

这个公式可以帮助你从摄氏温度换算成华氏温度。这是一个可以快速计算的公式。简单地将摄氏温度乘以2，再加上30:

(Celsius temp. x 2) 30 = Fahrenheit temp. (摄氏温度x 2) 30 =华氏温度。

Here's an example using 30 degrees C. 这里有一个使用30摄氏度的例子。

(30 x 2) 30 = 90 degrees F. (30 x 2) 30 = 90华氏度。

This is pretty close to the 86 degrees F reading you'd get using the more precise method (explained later).

这与你使用更精确的方法(稍后解释)得到的86华氏度读数非常接近。

To do a rough approximation of Celsius using Fahrenheit, reverse the earlier formula. Subtract 30 from the Fahrenheit degrees, then divide your answer by 2.

要用华氏度粗略地近似摄氏度，请颠倒前面的公式。华氏度减去30，然后将答案除以2。

(Fahrenheit temp. – 30) ÷ 2 = Celsius temp. (华氏温度- 30)÷ 2 =摄氏温度。

Let's say the Fahrenheit temperature is 80 degrees. The approximate Celsius temperature would be:

假设华氏温度是80度。大概的摄氏温度是:

(80 – 30) ÷ 2 = 25 C

如何将摄氏度转换为华氏度(精确计算)

If you're looking to get a more precise calculation, you can use this exact formula. You may want to have a calculator handy when you do this.

如果你想要得到更精确的计算结果，你可以使用这个精确的公式。计算的时候，你可能需要一个计算器。

(Celsius temp. × 1.8) 32 = Fahrenheit temp. (摄氏温度× 1.8) 32 =华氏温度。

Begin the conversion by multiplying the temperature in Celsius by 1.8 (or 9/5), then add 32 to your answer to get the Fahrenheit reading.

开始转换时，用摄氏温度乘以1.8(或9/5)，然后在你的答案上加上32，得到华氏温度读数。

Here's an example using 30 degrees Celsius. 这里有一个使用30摄氏度的例子。

(30 x 1.8) 32 = 86 F

如何将华氏度转换为摄氏度(精确计算)

When converting Fahrenheit to Celsius, you simply reverse the same equation above. Subtract 32 from the degrees in Fahrenheit, then divide your answer by 1.8.

当将华氏温度转换为摄氏温度时，只需将上面的等式颠倒。华氏度减去32，然后将你的答案除以1.8。

(Fahrenheit temp. – 32) ÷ 1.8 = Celsius temp. (华氏温度- 32)÷ 1.8 =摄氏温度。

Here is the formula in action starting with 80 degrees F: 下面是从80华氏度开始的公式:

(80 – 32) ÷ 1.8 = 26.6 C (or round up to 27 C) (80 - 32) ÷ 1.8 = 26.6 C(或四舍五入到27 C)
