Question 1

What's the formula for Celsius to Fahrenheit?

Accepted Answer

°F = (°C × 9/5) + 32. So 20°C = (20 × 1.8) + 32 = 68°F. The converter handles negatives and decimals.

Question 2

What's 0 Kelvin in Celsius?

Accepted Answer

0 K = -273.15°C — absolute zero, the lowest temperature physically possible.

Question 3

Is body temperature 37°C the same as 98.6°F?

Accepted Answer

Yes — 37.0°C = 98.6°F is the classic 'normal' body temperature reading.

Question 4

How do I quickly estimate °F from °C in my head?

Accepted Answer

Double the Celsius value and add 30. Example: 20°C → (20×2)+30 = 70°F. Close enough for weather forecasts (actual: 68°F).
