📊Temperature Scales

Celsius (°C)
Metric standard. Water freezes at 0°, boils at 100°.
Fahrenheit (°F)
US standard. Water freezes at 32°, boils at 212°.
Kelvin (K)
Scientific standard. Absolute scale starting at 0K.
Rankine (°R)
Absolute scale in Fahrenheit degrees.
Réaumur (°Ré)
Historical scale. Water freezes at 0°, boils at 80°.

💡Tips

• Quick formula: °F = (°C × 9/5) + 32

• Quick formula: °C = (°F - 32) × 5/9

• Kelvin never uses the degree symbol (K, not °K)

• Use the swap button to quickly reverse conversion

Frequently Asked Questions

How do I convert Celsius to Fahrenheit?

To convert Celsius to Fahrenheit, multiply by 9/5 (or 1.8) and add 32. Formula: °F = (°C × 9/5) + 32. For example, 20°C = (20 × 1.8) + 32 = 68°F.

What is the difference between Celsius and Kelvin?

Celsius and Kelvin use the same scale increment (1°C = 1K), but Kelvin starts at absolute zero (-273.15°C). To convert: K = °C + 273.15. Kelvin is used in scientific contexts and never has a degree symbol.

Why does the USA use Fahrenheit?

The USA adopted Fahrenheit before the metric system became widespread. Fahrenheit offers more granular whole-number readings for everyday temperatures (0-100°F covers most weather conditions), though most countries now use Celsius.

What temperature is the same in Celsius and Fahrenheit?

-40 degrees is the same in both Celsius and Fahrenheit (-40°C = -40°F). This is the only point where the two scales intersect.

Can temperature be negative in Kelvin?

No, Kelvin cannot be negative because it starts at absolute zero (0K = -273.15°C), the theoretical lowest possible temperature where all molecular motion stops.
