Temperature Converter
Convert between Celsius (°C) and Fahrenheit (°F)
Celsius to Fahrenheit
Algebraic Steps / Temperature Conversion Formula
Instructions
Convert temperature from Celsius (°C) to Fahrenheit (°F) or Fahrenheit (°F) to Celsius (°C) with precision. This calculator uses standard conversion formulas and shows accurate results instantly. To convert °C to °F: multiply by 9/5 and add 32. Formula: °F = (°C × 9/5) + 32. Example: 25°C = (25 × 9/5) + 32 = 45 + 32 = 77°F. To convert °F to °C: subtract 32 and multiply by 5/9. Formula: °C = (°F - 32) × 5/9. Example: 98.6°F = (98.6 - 32) × 5/9 = 66.6 × 5/9 = 37°C. Our temperature converter provides fast, accurate conversions between Celsius and Fahrenheit scales for all your temperature measurement needs.

Celsius (°C)
Celsius is the most commonly used temperature scale in most countries around the world. It is based on the freezing point of water (0°C) and the boiling point of water (100°C) at standard atmospheric pressure.
Fahrenheit (°F)
Fahrenheit is primarily used in the United States and some Caribbean countries. It was developed by Daniel Gabriel Fahrenheit in the early 18th century.
Conversion Formulas
To convert between Celsius and Fahrenheit, use these formulas: Celsius to Fahrenheit: °F = (°C × 9/5) + 32, Fahrenheit to Celsius: °C = (°F - 32) × 5/9.
Common Temperature References
Here are some common temperature references: 0°C (32°F) is the freezing point of water, 20°C (68°F) is room temperature, 37°C (98.6°F) is human body temperature, and 100°C (212°F) is the boiling point of water.
Temperature Scale Comparison
Celsius is used in most countries worldwide, while Fahrenheit is primarily used in the United States. Understanding both scales is important for international communication and travel.
Practical Applications
Temperature conversion is essential in cooking, weather forecasting, scientific research, and many other fields where precise temperature measurements are required.
