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

  1. For Weather: Use Celsius internationally, Fahrenheit in the US
  2. For Cooking: Use Celsius for most recipes, Fahrenheit for US recipes
  3. For Science: Use Kelvin for absolute temperature measurements
  4. For Engineering: Use the scale specified in your project requirements

Common Temperature Ranges

  • Freezing: Below 0°C (32°F)
  • Cold: 0-10°C (32-50°F)
  • Cool: 10-20°C (50-68°F)
  • Room Temperature: 20-25°C (68-77°F)
  • Warm: 25-30°C (77-86°F)
  • Hot: Above 30°C (86°F)

Applications

  • Weather Forecasting: Daily temperature reporting and climate data
  • Cooking: Oven temperatures and food safety guidelines
  • Science: Chemical reactions and physical property measurements
  • Medicine: Body temperature monitoring and medical procedures
  • Industrial Processes: Manufacturing temperature control and quality assurance

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
