Question 1

What is the formula to convert Celsius to Fahrenheit?

Accepted Answer

The exact formula is (°C × 9/5) + 32 = °F. For example, 100°C = (100 × 9/5) + 32 = 212°F. This formula is algebraically exact — there is no rounding.

Question 2

How do I convert Fahrenheit to Celsius?

Accepted Answer

To convert Fahrenheit to Celsius, use (°F − 32) × 5/9 = °C. For example, 98.6°F = (98.6 − 32) × 5/9 = 37°C (normal body temperature).

Question 3

What is 37 degrees Celsius in Fahrenheit?

Accepted Answer

37°C equals exactly 98.6°F. This is normal human body temperature. Using the formula: (37 × 9/5) + 32 = 66.6 + 32 = 98.6°F.

Question 4

At what temperature are Celsius and Fahrenheit the same?

Accepted Answer

Celsius and Fahrenheit are equal at −40 degrees. This is the only point where both scales intersect. You can verify: (−40 × 9/5) + 32 = −72 + 32 = −40°F.

Question 5

What is 0 degrees Celsius in Fahrenheit?

Accepted Answer

0°C equals 32°F. This is the freezing point of water at standard atmospheric pressure. Using the formula: (0 × 9/5) + 32 = 32°F.

Question 6

How do I convert Celsius to Fahrenheit in my head?

Accepted Answer

A quick mental math shortcut: double the Celsius temperature, subtract 10%, then add 32. For example, 20°C → 40 → 36 → 68°F (exact: 68°F). This gives accuracy within 1–2 degrees for everyday temperatures.
