Exact conversion relationship
Temperature scales use different zero points and intervals. Kelvin and Rankine are absolute scales, while Celsius and Fahrenheit use familiar water reference points.
Where this is useful
A multi-scale chart is useful for science, engineering, weather, education, cooking and comparing specifications from different countries.
Understanding the result
Absolute zero is 0 K or −273.15 °C. At standard atmospheric pressure water freezes at 0 °C and boils at 100 °C.
Important measurement note
Boiling temperature changes with atmospheric pressure, and normal body temperature is a range rather than one universal value.
Precision and rounding
The calculator keeps full precision internally and rounds only displayed values. Match the chosen precision to the accuracy of the original measurement.
Batch conversion for lists
Paste a short list to create a clean two-column result table for recipes, specifications, logs or comparisons.
