Understanding Temperature Scales
Three Main Scales
Celsius (°C), Fahrenheit (°F), and Kelvin (K) are the most widely used temperature scales worldwide.
Water Boiling Point
100°C = 212°F = 373.15K - The temperature at which water boils at sea level.
Water Freezing Point
0°C = 32°F = 273.15K - The temperature at which water freezes.
Meeting Point
-40°C = -40°F - The only temperature where Celsius and Fahrenheit are equal.

Temperature Conversion Formulas
Celsius ↔ Fahrenheit
Celsius to Fahrenheit:
°F = (°C × 9/5) + 32
Fahrenheit to Celsius:
°C = (°F - 32) × 5/9
Celsius ↔ Kelvin
Celsius to Kelvin:
K = °C + 273.15
Kelvin to Celsius:
°C = K - 273.15
Fahrenheit ↔ Kelvin
Fahrenheit to Kelvin:
K = (°F - 32) × 5/9 + 273.15
Kelvin to Fahrenheit:
°F = (K - 273.15) × 9/5 + 32
