Question 1

How to convert Celsius to Fahrenheit?

Accepted Answer

Multiply Celsius by 9/5, then add 32. Formula: °F = (°C × 9/5) + 32. Example: 25°C × 9/5 = 45 + 32 = 77°F.

Question 2

How to convert Fahrenheit to Celsius?

Accepted Answer

Subtract 32 from Fahrenheit, then multiply by 5/9. Formula: °C = (°F - 32) × 5/9. Example: 77°F - 32 = 45 × 5/9 = 25°C.

Question 3

How to convert Celsius to Kelvin?

Accepted Answer

Add 273.15 to Celsius. Formula: K = °C + 273.15. Example: 25°C + 273.15 = 298.15 K. Kelvin is the scientific temperature scale starting at absolute zero.

Question 4

What is absolute zero?

Accepted Answer

Absolute zero is the lowest possible temperature (0 Kelvin, -273.15°C, -459.67°F). At this temperature, particles stop moving completely.

Question 5

What is normal body temperature?

Accepted Answer

Normal human body temperature is 37°C (98.6°F). Fever starts at 38°C (100.4°F).
