在摄氏度、华氏度和开尔文温度之间转换

结果
请输入要转换的值
常见参考点
水的冰点0°C = 32°F = 273.15K
人体体温37°C = 98.6°F = 310.15K
水的沸点100°C = 212°F = 373.15K
绝对零度-273.15°C = -459.67°F = 0K
公式：°F = °C × 9/5 + 32，K = °C + 273.15。水在 0°C / 32°F / 273.15K 时结冰。

    Type the temperature you want to convert into the input field. Negative values are supported.

  2. 2

    Select the source scale

    Choose the temperature scale you are converting from: Celsius, Fahrenheit, or Kelvin.

  3. 3

    Choose the target scale

    Pick the scale to convert to, or use the swap button to reverse the direction instantly.

  4. 4

    Check common references

    Below the result, a reference table shows common temperature points (freezing, boiling, body temp, absolute zero) in all three scales.

Frequently Asked Questions

How do I convert Celsius to Fahrenheit?
Multiply the Celsius value by 9/5 (or 1.8) and add 32. For example, 100°C × 1.8 + 32 = 212°F.
What is absolute zero?
Absolute zero is the lowest possible temperature: 0 Kelvin, −273.15°C, or −459.67°F. At this point, molecular motion theoretically stops.
When should I use Kelvin?
Kelvin is the SI unit for temperature used in scientific contexts. It starts at absolute zero and uses the same increment size as Celsius.
What is normal human body temperature in Fahrenheit?
Normal body temperature is approximately 98.6°F (37°C or 310.15 K), though it can vary slightly from person to person.
