🧮 Conversion Formulas

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

About Temperature Scales

🌡️ Celsius (°C)

The metric system standard. Water freezes at 0°C and boils at 100°C at sea level. Used worldwide for weather, cooking, and science.

🇺🇸 Fahrenheit (°F)

Primarily used in the United States. Water freezes at 32°F and boils at 212°F. Often preferred for weather because it offers more precision for everyday temperatures.

🔬 Kelvin (K)

The SI unit for scientific measurements. Starts at absolute zero (−273.15°C), where molecular motion stops. No degree symbol is used.

💡 Fun Fact

At -40°, Celsius and Fahrenheit are exactly the same! This is the only point where the two scales intersect.
