Temperature Converter

Convert between Celsius, Fahrenheit, and Kelvin in one click.

Celsius (°C)

(input)

Fahrenheit (°F)

Detailed results
Kelvin (K)	273.15

What this result means

0°C = 32.0°F

How this is calculated

°C → °F: F = C × 9/5 + 32
°F → °C: C = (F − 32) × 5/9
°C → K:  K = C + 273.15
K  → °C: C = K − 273.15

Temperature conversion

The three scales in everyday use:

| Scale | Freezing | Boiling | Absolute zero | |-------|----------|---------|---------------| | Celsius (°C) | 0 | 100 | −273.15 | | Fahrenheit (°F) | 32 | 212 | −459.67 | | Kelvin (K) | 273.15 | 373.15 | 0 |

Useful reference points: - Body temperature: 37°C = 98.6°F - Room temperature: 20°C = 68°F - Oven at 180°C = 356°F - −40°C = −40°F (the only point where both scales are equal)

Assumptions

Uses exact conversion formulas: F = C × 9/5 + 32 and K = C + 273.15.
Results rounded to 4 decimal places.

Frequently asked questions

›How do I convert Celsius to Fahrenheit?

Multiply by 9/5, then add 32. Example: 20°C × 9/5 = 36, then 36 + 32 = 68°F.

›How do I convert Fahrenheit to Celsius?

Subtract 32, then multiply by 5/9. Example: 68°F − 32 = 36, then 36 × 5/9 = 20°C.

›What is 0 Kelvin in Celsius?

0 Kelvin (absolute zero) = −273.15°C. It is the coldest temperature theoretically possible — no thermal energy whatsoever.

›At what temperature are Celsius and Fahrenheit equal?

At −40°. Both scales give the same number at exactly −40°C = −40°F.
