What is Temperature Conversion?

Temperature conversion is the process of converting temperature measurements from one scale to another. Our temperature converter tool supports the most common temperature scales including Celsius, Fahrenheit, and Kelvin, making it easy to switch between these systems for cooking, weather monitoring, scientific experiments, and industrial applications.

Celsius is the metric scale used worldwide and is defined by setting the freezing point of water at 0°C and boiling point at 100°C. Fahrenheit is primarily used in the United States with water freezing at 32°F and boiling at 212°F. Kelvin is the scientific scale based on absolute zero, with 0K representing the lowest possible temperature. Quick conversion between these scales is essential for international travel, scientific research, cooking, and weather forecasting.

Simply enter your value in the "From" field, select the original temperature scale, choose your target scale in the "To" field, and the converter will instantly display the converted result along with the conversion formula.

Temperature Conversion Examples

Cooking Example

Converting oven temperatures:

  • 180°C = 356°F
  • 200°C = 392°F
  • 350°F = 177°C

Weather Example

Converting weather temperatures:

  • 25°C = 77°F
  • 32°F = 0°C (freezing point)
  • -40°C = -40°F

Scientific Example

Converting to scientific scale:

  • 0°C = 273.15K
  • 100°C = 373.15K
  • -273.15°C = 0K (absolute zero)

Frequently Asked Questions

How do I convert Celsius to Fahrenheit?

To convert Celsius to Fahrenheit, multiply the Celsius value by 9/5 and add 32. For example, 25°C × 9/5 + 32 = 77°F.

What is the formula for Fahrenheit to Celsius?

To convert Fahrenheit to Celsius, subtract 32 from the Fahrenheit value and multiply by 5/9. For example, 77°F - 32 × 5/9 = 25°C.

What is absolute zero?

Absolute zero is -273.15°C or 0K, which is the lowest possible temperature where all molecular motion theoretically stops. This is the base of the Kelvin temperature scale.

How do I convert Celsius to Kelvin?

To convert Celsius to Kelvin, add 273.15 to the Celsius value. For example, 25°C + 273.15 = 298.15K.

What is the boiling point of water in Fahrenheit?

Water boils at 212°F (100°C) at standard atmospheric pressure. The freezing point is 32°F (0°C).
