About Temperature Conversion

Temperature is a physical quantity that expresses hot and cold. It is measured with a thermometer calibrated in one or more temperature scales.

Common Temperature Scales

Celsius (°C) - Also known as centigrade, widely used around the world and in science. Water freezes at 0°C and boils at 100°C at sea level.

Fahrenheit (°F) - Commonly used in the United States. Water freezes at 32°F and boils at 212°F at sea level.

Kelvin (K) - The SI base unit of temperature. Used primarily in scientific contexts. Absolute zero is 0 K, equivalent to -273.15°C.

Conversion Formulas

Celsius to Fahrenheit: °F = (°C × 9/5) + 32

Fahrenheit to Celsius: °C = (°F - 32) × 5/9

Celsius to Kelvin: K = °C + 273.15

Kelvin to Celsius: °C = K - 273.15

Fahrenheit to Kelvin: K = (°F - 32) × 5/9 + 273.15

Kelvin to Fahrenheit: °F = (K - 273.15) × 9/5 + 32
