Why does Kelvin never go below zero?
Kelvin uses absolute zero as 0, so temperatures cannot drop below that limit. The converter enforces the threshold automatically.

Collect the data points listed below and double-check their units. Keeping an organized “givens” list is one of the fastest ways to reduce math errors and impress exam graders.
Step 1
Enter a value in any supported scale.
Step 2
Select the unit that matches your input.
Step 3
Review the converted temperatures across the remaining scales.
Kelvin uses absolute zero as 0, so temperatures cannot drop below that limit. The converter enforces the threshold automatically.
Yes—negative values are supported for Celsius and Fahrenheit, and the equivalent Kelvin or Rankine values adjust accordingly.
