Temperature Converter
Convert temperatures among Celsius, Fahrenheit, Kelvin, Rankine, and Reaumur scales with instant precision.
Run tool
Convert temperature values between Celsius, Fahrenheit, Kelvin, Rankine, and Reaumur scales quickly and accurately. Whether you need to switch weather readings from Celsius to Fahrenheit, translate laboratory measurements into Kelvin for thermodynamics calculations, or work with specialized engineering scales like Rankine and Reaumur, this converter handles the arithmetic directly.
Enter your starting temperature into the value field, choose the original unit, and select your desired target unit. By default, the tool begins with 0 Celsius and converts to Fahrenheit. When you submit your input, the tool calculates the primary converted reading rounded to 10 decimal places, preventing unnecessary rounding drift in multi-step calculations. Along with your chosen target scale, the results display equivalent temperatures for all five supported scales at once, giving you a full comparative view across absolute and relative temperature systems. Both positive and negative temperatures are supported across every scale.
Instructions
- Enter a numerical temperature value into the Value field.
- Select the starting temperature scale from the From unit menu.
- Select your target temperature scale from the To unit menu.
- Click Run to calculate the converted temperature.
Examples
- Convert 100 Celsius to Fahrenheit to get 212 Fahrenheit for standard boiling water temperature.
- Convert 0 Kelvin to Celsius to find absolute zero at -273.15 Celsius.
- Convert 68 Fahrenheit to Kelvin to obtain 293.15 Kelvin for room temperature physics problems.
