🌡️ Temperature Converter - Celsius, Fahrenheit, Kelvin
Quick conversion between all temperature units
📌 Conversion Formulas
- °F = °C × 9/5 + 32
- K = °C + 273.15
- °R = (°C + 273.15) × 9/5
Fact: Absolute zero = -273.15°C = 0 K
Convert Between Celsius, Fahrenheit, Kelvin and Rankine
This free converter changes a temperature from one scale to another instantly. It supports the four scales people meet most often: Celsius, used in most of the world for weather and cooking; Fahrenheit, common in the United States; Kelvin, the SI unit used in science; and Rankine, an absolute scale tied to Fahrenheit and used in some engineering fields. Type a value once and read it in every scale.
The conversions follow the standard relationships between the scales. Celsius and Fahrenheit share the well-known formula where each Celsius degree equals 1.8 Fahrenheit degrees with a 32-degree offset, while Kelvin simply adds about 273.15 to Celsius so that zero Kelvin marks absolute zero, the point where molecular motion is at its minimum. Because the math is exact, the tool is reliable for homework, lab notes, recipes, and travel.
Where People Use It
Students use it to check physics and chemistry answers, travelers translate a foreign forecast into the scale they understand, and home cooks convert oven temperatures between Celsius and Fahrenheit recipes. Engineers and weather enthusiasts rely on Kelvin and Rankine for absolute-temperature work. Whatever your reason, enter a number and the converted values appear right away, with no rounding surprises for everyday use.
