Celsius to Fahrenheit Conversion FAQ

What is the formula to convert Celsius to Fahrenheit?

Multiply the Celsius temperature by 9/5, then add 32: °F = °C × 9/5 + 32. For example, 37 °C × 9/5 + 32 = 98.6 °F.

What is 37 °C in Fahrenheit?

37 °C equals 98.6 °F — the traditional value for normal human body temperature.

At what temperature are Celsius and Fahrenheit equal?

At −40 degrees. Because the scales converge with opposite offsets, −40 °C and −40 °F are exactly the same temperature.

How do I convert Fahrenheit to Celsius?

Subtract 32, then multiply by 5/9: °C = (°F − 32) × 5/9. For example, (350 − 32) × 5/9 ≈ 176.7 °C for a common oven setting.
