FAQs

How do I convert Celsius to Fahrenheit?

Multiply the Celsius temperature by 9/5 (or 1.8), then add 32. For example, 25°C × 1.8 + 32 = 77°F.

What is absolute zero?

Absolute zero is the lowest possible temperature, where all molecular motion stops. It equals 0 Kelvin, -273.15°C, or -459.67°F.

Why is Kelvin used in science?

Kelvin is an absolute temperature scale starting at absolute zero, making it ideal for scientific calculations. It avoids negative numbers in thermodynamic equations.

At what temperature are Celsius and Fahrenheit equal?

Celsius and Fahrenheit are equal at -40 degrees. Both -40°C and -40°F represent the same temperature.
