How to Calculate & Formula Details

Mathematical Model Formula°F = °C * 9/5 + 32. °C = (°F - 32) * 5/9. K = °C + 273.15.

A temperature converter switches values between the three most common temperature scales: Celsius (used by most of the world), Fahrenheit (used in the US), and Kelvin (used in science).

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

Reference Points

Water freezes at 0°C / 32°F / 273.15K and boils at 100°C / 212°F / 373.15K at standard atmospheric pressure.

Frequently Asked Questions

What is 0°C in Fahrenheit?

0°C equals 32°F, the freezing point of water at sea level.

Why does Kelvin never go negative?

Kelvin is an absolute temperature scale starting at absolute zero (0K = -273.15°C), the theoretical point where all molecular motion stops, so negative Kelvin values do not occur in classical physics.

How do I convert body temperature from Fahrenheit to Celsius?

Subtract 32 from the Fahrenheit value, then multiply by 5/9. For example, 98.6°F becomes (98.6 - 32) × 5/9 = 37°C.
