Temperature Scales Explained
The Celsius scale is used by most countries worldwide and in scientific contexts. It sets the freezing point of water at 0°C and the boiling point at 100°C at sea level atmospheric pressure.
Primarily used in the United States, the Fahrenheit scale sets the freezing point of water at 32°F and the boiling point at 212°F. The human body temperature is approximately 98.6°F on this scale.
The Kelvin scale is the primary temperature scale used in scientific work. It is an absolute scale where 0K represents absolute zero (-273.15°C), the theoretical point where all molecular motion stops.

Temperature Conversion Formulas
- 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
- Fahrenheit to Kelvin: K = (°F – 32) × 5/9 + 273.15
- Kelvin to Fahrenheit: °F = (K – 273.15) × 9/5 + 32

Frequently Asked Questions About Temperature Conversion
How do I convert Celsius to Fahrenheit?
To convert Celsius to Fahrenheit, multiply the Celsius temperature by 9/5 and then add 32. For example, 20°C equals 68°F (20 × 9/5 = 36, then 36 + 32 = 68). Our Temperature Converter automates this calculation for you.
What is 100 degrees Fahrenheit in Celsius?
100 degrees Fahrenheit is approximately 37.78 degrees Celsius. This is calculated using the formula: (°F – 32) × 5/9 = (100 – 32) × 5/9 = 68 × 5/9 ≈ 37.78°C.
What is absolute zero in different temperature scales?
Absolute zero, the theoretical lowest possible temperature, is -273.15°C, -459.67°F, and 0K. At this temperature, particles have minimal thermal motion.
Why does the US use Fahrenheit instead of Celsius?
The United States continues to use the Fahrenheit scale primarily due to historical precedent and cultural习惯. While most countries have adopted Celsius, the US maintains Fahrenheit for everyday temperature measurements, though scientific work uses Celsius and Kelvin.
Is there a quick way to estimate Celsius to Fahrenheit conversion?
A quick approximation for converting Celsius to Fahrenheit is to double the Celsius temperature and add 30. For example, 20°C would be approximately 20×2+30=70°F (the exact conversion is 68°F). This method gives a rough estimate that’s usually within a few degrees of the actual value.
