How to Convert Between Temperature Scales

Formula

°F = °C × 9/5 + 32; °C = (°F − 32) × 5/9;
K = °C + 273.15

Temperature conversion is essential in science, cooking, travel, and daily life. The three main scales are Celsius (used worldwide), Fahrenheit (used in the US), and Kelvin (used in science). This converter handles all six possible conversions between the three scales instantly.

Simply enter a temperature value and select the source unit. The calculator displays the equivalent value in all three temperature scales so you can quickly compare readings across systems.

Common use cases:

  • Converting weather forecasts between Celsius and Fahrenheit
  • Science experiments requiring Kelvin
  • Cooking temperature conversions
