Frequently asked questions

How do I convert Celsius to Fahrenheit?

Multiply the Celsius value by 9/5 (1.8) and add 32. For example, 25 degrees C is 25 x 1.8 + 32 = 77 degrees F. Water freezes at 0 C (32 F) and boils at 100 C (212 F) at standard atmospheric pressure.

How do I convert Fahrenheit to Celsius?

Subtract 32 and multiply by 5/9. For example, 98.6 degrees F becomes (98.6 - 32) x 5/9 = 37 degrees C, normal body temperature. The tool shows the formula it used, so you can follow the arithmetic step by step.

How do I convert Celsius to Kelvin?

Add 273.15 to the Celsius value. So 0 degrees C is 273.15 K and 100 degrees C is 373.15 K. Kelvin has no degree symbol, and absolute zero, the lowest possible temperature, is 0 K or -273.15 C (-459.67 F).

At what temperature are Celsius and Fahrenheit equal?

They are equal at -40 degrees. Using F = C x 1.8 + 32, setting F equal to C gives C = -40, so -40 C is the same temperature as -40 F. It is the only point where the two scales agree.

What are room temperature and body temperature in Celsius and Fahrenheit?

Room temperature is commonly taken as 20 C, which is 68 F or 293.15 K. Normal human body temperature is about 37 C, which is 98.6 F or 310.15 K. These reference points are also listed on the page for quick comparison.

Can a temperature go below zero Kelvin?

No. Zero Kelvin is absolute zero, the point where particles have minimal thermal motion, so nothing can be colder. A value below 0 K is physically meaningless, and the equivalent limits are -273.15 C and -459.67 F.

Is my data shared when using the Temperature Converter?

No. Toolskyt operates under a zero-server policy. All calculations, data formatting, and file exports are executed locally on your machine.

Do I need to sign up or pay to use the Temperature Converter?

No, this tool is 100% free. There are no limits, sign-ups, subscriptions, or hidden charges required.
