开尔文到摄氏公式
开尔文和摄氏度是两个温度标度。两种秤都以自己独特的方式使用。开尔文标度主要被科学家用来测量光源的色温。另一方面,摄氏温标用于测量水温等一般用途。这两个比例可以很容易地从一个转换到另一个。在直接到开尔文到摄氏度之前。让我们更多地了解这些秤以及它们最常使用的地方。
开尔文
开尔文是温标。它的单位是(K),因为它是一个绝对比例,我们不使用度数。开尔文以第一代开尔文男爵威廉汤姆森的名字命名。 0(零) 开尔文定义绝对零值,这意味着在此温度下粒子的动能非常小。在物理科学中,开尔文是测量温度的主要单位。
摄氏度
摄氏度也是一个温度标度。它的单位是摄氏度(°C)。它以 1948 年天文学家安德斯·摄氏命名。在摄氏温度范围内,水在 0°C 时结冰,在正常条件下在 100°C 时沸腾。除美国、伯利兹、帕劳、巴哈马和开曼群岛等国家外,大多数国家都使用摄氏温度标度作为官方温度标度。
开尔文到摄氏度公式
The formula for Fahrenheit to Celsius is Celsius(°C )= Kelvin – 273.15°.

示例问题
问题 1:将 319.15 K 转换为 °C。
解决方案:
Given,
The temperature in Kelvin scale = 319.15 K
According to the relationship between Kelvin scale and Celsius scale,
C = k – 273.15
Inserting the values,
C = 319.15 – 273.15
C = 46°C.
The value of temperature on the Celsius scale is 46 °C.
问题2:500K是多少摄氏度?
解决方案:
Given,
The temperature in Kelvin scale = 500 K
According to the relationship between Kelvin scale and Celsius scale,
C = k – 273.15
Inserting the values,
C = 500 – 273.15
C = 226.85 °C
The value of temperature on the Celsius scale is 226.85 °C.
问题 3:开尔文的什么温度被称为“绝对零”?
回答:
When the temperature is 0 (Zero) K, then it is called Absolute Null. Because at this temperature kinetic value of the atoms is lowest.
问题 4:在摄氏多少度时,开尔文的温度为零?
解决方案:
Given,
According to Question Temperature in Kelvin scale = 0 K
According to the relationship between Kelvin scale and Celsius scale,
C = k – 273.15
Inserting the values,
C = 0 – 273.15
C =273.15 °C
The value of temperature on the Celsius scale is 273.15°C.When the temperature in Kelvin is Zero.
问题 5:将 775 K 转换为° C。
解决方案:
Given,
The temperature in Kelvin scale = 775 K
According to the relationship between Kelvin scale and Celsius scale,
C = k – 273.15
Inserting the values,
C = 775 – 273.15
C = 501.85 °C
The value of temperature on the Celsius scale is 501.85 °C.
问题 6:开尔文的温度值是多少。摄氏度的温度为零(0)?
解决方案:
Given,
According to the question value of temperature in Degree Celsius is = 0°C.
According to the relationship between Kelvin scale and Celsius scale,
C = K – 273.15
Inserting the values,
0 = K – 273.15
K = 273.15
The value of temperature on the Kelvin scale is 273.15 K . When the temperature in Degree Celsius is Zero.
