About Temperature Conversion
Temperature is a measure of the average kinetic energy of particles in a substance. Different temperature scales are used around the world, with Celsius and Fahrenheit being the most common.
Common Temperature Conversions
- Celsius to Fahrenheit: °F = (°C × 9/5) + 32
- Fahrenheit to Celsius: °C = (°F - 32) × 5/9
- Celsius to Kelvin: K = °C + 273.15
- Kelvin to Celsius: °C = K - 273.15
Key Temperature Reference Points
- Absolute Zero: -273.15°C, -459.67°F, 0K
- Freezing Point of Water: 0°C, 32°F, 273.15K
- Boiling Point of Water: 100°C, 212°F, 373.15K
- Room Temperature: 20-25°C, 68-77°F, 293-298K
- Human Body Temperature: 37°C, 98.6°F, 310K
When to Use Different Temperature Scales
- Celsius (°C): Used worldwide, standard in most countries
- Fahrenheit (°F): Primarily used in the United States
- Kelvin (K): Used in scientific research and calculations
- Rankine (°R): Used in some engineering applications
Tips for Temperature Conversion
- For Weather: Use Celsius internationally, Fahrenheit in the US
- For Cooking: Use Celsius for most recipes, Fahrenheit for US recipes
- For Science: Use Kelvin for absolute temperature measurements
- For Engineering: Use the scale specified in your project requirements
Common Temperature Ranges
- Freezing: Below 0°C (32°F)

Unit Definitions
Celsius (°C)
A temperature scale where 0°C is the freezing point of water and 100°C is the boiling point.
Formula: °F = (°C × 9/5) + 32
Fahrenheit (°F)
A temperature scale commonly used in the United States.
Formula: °C = (°F - 32) × 5/9
Kelvin (K)
The base unit of temperature in the International System of Units (SI).
Formula: K = °C + 273.15
Rankine (°R)
An absolute temperature scale based on Fahrenheit degrees.
Formula: °R = °F + 459.67
