Convert temperatures between Celsius, Fahrenheit, and Kelvin scales quickly and accurately with our free online temperature converter. Precise formulas and instant results.
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
Temperature is a physical property that expresses hot and cold. It is the manifestation of thermal energy, present in all matter, which is the source of the occurrence of heat, a flow of energy, when a body is in contact with another that is colder. Temperature is measured with a thermometer. There are several scales and units of temperature. The most commonly used are Celsius (°C), Fahrenheit (°F), and Kelvin (K). The Celsius scale is used in most countries worldwide, while Fahrenheit is primarily used in the United States. The Kelvin scale is used in scientific contexts and is an absolute thermodynamic temperature scale. The relationships between these units are defined by precise conversion formulas. Our temperature converter allows you to easily convert between these three common temperature scales with high precision.
