🌡️ Kelvin Converter
Translate absolute temperatures into everyday scales.
Useful for scientific, engineering, and cooking contexts where Kelvin readings must be compared to Celsius or Fahrenheit values.
How to Use This Calculator
Enter Kelvin
Provide the temperature measured in Kelvin.
Review conversions
Celsius, Fahrenheit, and Rankine equivalents appear instantly.
Apply the results
Use the converted values in reports, control systems, or recipes.
Formula
°C = K − 273.15
°F = (K − 273.15) × 9/5 + 32
°R = K × 9/5
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Kelvin is the absolute temperature scale used in science and engineering. Converting it to Celsius or Fahrenheit helps communicate findings to broader audiences and verify that process temperatures remain within acceptable ranges.
Because Kelvin has the same increments as Celsius, the conversions rely on a simple offset, but Fahrenheit requires the 9/5 factor.
Rankine is included for engineering teams that work with imperial derivatives of absolute temperature.
Frequently Asked Questions
Can Kelvin be negative?
In theoretical physics yes, but most practical applications stay at or above 0 K. The calculator accepts negative values but verify they make sense for your scenario.
How do I convert back to Kelvin?
Add 273.15 to Celsius, or use the Kelvin converter with the appropriate input field.
Why include Rankine?
Rankine is the Fahrenheit-based absolute scale used in some thermodynamics and aerospace calculations.
Does the tool handle very large numbers?
Yes. JavaScript handles typical laboratory and industrial temperature ranges without issue.
