Temperature Scales Explained

Understanding temperature units is key before performing conversions. Here are the most widely used scales:

Celsius (°C)

  • Based on the freezing point (0°C) and boiling point (100°C) of water.

  • Commonly used worldwide for weather and scientific calculations.

Fahrenheit (°F)

  • Primarily used in the United States.

  • Freezing point of water is 32°F, boiling point is 212°F.

Kelvin (K)

  • Used in scientific and engineering applications.

  • Absolute scale starting from 0K (absolute zero).

  • 0°C equals 273.15K.


Temperature Conversion Formulas

Accurate conversions rely on simple formulas. Let’s break down the most common ones:

Celsius to Fahrenheit

°F=(°C×9/5)+32°F = (°C × 9/5) + 32

Fahrenheit to Celsius

°C=(°F−32)×5/9°C = (°F − 32) × 5/9

Celsius to Kelvin

K=°C+273.15K = °C + 273.15

Kelvin to Celsius

°C=K−273.15°C = K − 273.15

Fahrenheit to Kelvin

K=(°F−32)×5/9+273.15K = (°F − 32) × 5/9 + 273.15

Kelvin to Fahrenheit

°F=(K−273.15)×9/5+32°F = (K − 273.15) × 9/5 + 32

These formulas form the backbone of any Temperature conversion calculator and are implemented in online tools like CalcsHub.com for instant results.
