Question 1

What is 20°C in Fahrenheit?

Accepted Answer

20°C = 68°F. This is a comfortable room temperature — a typical mild spring day in the UK.

Question 2

What is 37°C in Fahrenheit?

Accepted Answer

37°C = 98.6°F. This is normal human body temperature. A fever is typically 38°C (100.4°F) or above.

Question 3

What is 100°F in Celsius?

Accepted Answer

100°F = 37.8°C — just above normal body temperature, the threshold for a fever in Fahrenheit.

Question 4

How do I convert Celsius to Fahrenheit in my head?

Accepted Answer

Multiply °C by 1.8 (or 9/5) then add 32. For a quick rough estimate: double the Celsius and add 30. So 20°C × 2 + 30 = 70°F (exact: 68°F). Close enough for a weather check.

Question 5

What is 0°C in Fahrenheit?

Accepted Answer

0°C = 32°F. This is the freezing point of water at standard atmospheric pressure.

Question 6

What is 180°C in Fahrenheit?

Accepted Answer

180°C = 356°F. This is a common conventional oven temperature for baking (160°C fan = 356°F). Gas mark equivalents: 160°C = gas mark 3, 180°C = gas mark 4, 200°C = gas mark 6.

Question 7

At what temperature are Celsius and Fahrenheit the same?

Accepted Answer

-40° is the only temperature where both scales agree: -40°C = -40°F. This is because the Fahrenheit and Celsius scales cross at this point mathematically. It is well below anything you would encounter in everyday life.
