What is Temperature Conversion?
Temperature conversion is the process of converting temperature measurements from one scale to another. The three most common temperature scales are Celsius (°C), Fahrenheit (°F), and Kelvin (K). Understanding how to convert between these scales is essential for weather reporting, cooking, scientific research, and international communication. Whether you're preparing a recipe or conducting a physics experiment, accurate temperature conversion can significantly affect your results.
Our temperature converter supports conversions between Celsius, Fahrenheit, and Kelvin. This tool helps you quickly convert temperatures for weather forecasts, recipe adjustments, laboratory work, and understanding temperature references from different countries. With precise conversions, you can ensure that your projects are accomplished efficiently and accurately.
How to Convert Temperature
Temperature conversion formulas differ from simple multiplication because each scale has different zero points and intervals. Celsius and Fahrenheit use different reference points, while Kelvin is an absolute scale starting at absolute zero. Understanding these differences is crucial when performing calculations.
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 - 273.15Example: Convert 20°C to Fahrenheit.
Formula: F = (C × 9/5) + 32
Calculation: F = (20 × 9/5) + 32 = 36 + 32 = 68
Result: 20°C equals 68°F
Understanding Temperature Scales
- Celsius (°C):The metric temperature scale used worldwide. Water freezes at 0°C and boils at 100°C at standard atmospheric pressure. Named after Anders Celsius.
- Fahrenheit (°F):Commonly used in the United States. Water freezes at 32°F and boils at 212°F. Named after Daniel Gabriel Fahrenheit.
- Kelvin (K):The absolute temperature scale used in scientific applications. Absolute zero (0 K) is -273.15°C. No degree symbol is used with Kelvin.

Frequently Asked Questions about Temperature
How do I convert Celsius to Fahrenheit?
Multiply Celsius by 9/5 and add 32. For example, 25°C × 9/5 + 32 = 77°F.
What is absolute zero in different scales?
Absolute zero is 0 K, -273.15°C, or -459.67°F. It's the theoretical lowest possible temperature where all molecular motion stops.
At what temperature do Celsius and Fahrenheit equal each other?
Celsius and Fahrenheit are equal at -40 degrees (-40°C = -40°F). This is the only point where both scales have the same numerical value.
Why is Kelvin used in science?
Kelvin is an absolute scale starting at absolute zero, making it ideal for scientific calculations involving temperature ratios and thermodynamic equations.
What is room temperature in different scales?
Room temperature is approximately 20-25°C (68-77°F or 293-298 K), though this can vary depending on location and personal preference.
