🌡️ Temperature Scales Explained
Celsius (°C): The most common scale used worldwide. 0°C is the freezing point of water, and 100°C is the boiling point. Named after Anders Celsius.
Fahrenheit (°F): Primarily used in the United States. Water freezes at 32°F and boils at 212°F. Developed by Daniel Gabriel Fahrenheit.
Kelvin (K): The scientific unit for temperature. 0 K is absolute zero - the coldest possible temperature. Named after Lord Kelvin. Used in physics and chemistry.

❓ Frequently Asked Questions
How do I convert Celsius to Fahrenheit quickly?
For a quick mental calculation, multiply Celsius by 1.8 and add 32. For exact conversion: (°C × 9/5) + 32 = °F. Our calculator does this instantly!
What is absolute zero and why is it important?
Absolute zero is the lowest possible temperature where particles have minimum thermal motion. It's 0 Kelvin or -273.15°C. It's important in thermodynamics and quantum mechanics.
Why are there different temperature scales?
Celsius is used worldwide for everyday purposes. Fahrenheit is used primarily in the US. Kelvin is the scientific standard used in physics and engineering because it starts at absolute zero.
What's the relationship between Celsius and Kelvin?
Kelvin = Celsius + 273.15. The size of 1 Kelvin is the same as 1 degree Celsius, but the zero points are different. Celsius starts at water's freezing point, while Kelvin starts at absolute zero.
