Rankine to Kelvin Converter
Convert degrees Rankine to kelvin instantly. Free, bidirectional, and fully in-browser.
Convert degrees Rankine to kelvin with the formula K = °R × 0.555556 — type any temperature to see the result at once. This Rankine to Kelvin converter is a client-side tool: it applies the exact temperature formula (K = °R × 0.555556) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert kelvin back to degrees Rankine. A reference table lists common Rankine values already converted, and nothing you enter is sent to a server.

Why use Rankine to Kelvin Converter
Instant, both ways
The result updates as you type, and the swap button flips the conversion to kelvin → Rankine without reloading.
Exact Temperature math
The conversion uses the exact formula K = °R × 0.555556, so the number matches a manual calculation to the decimal places you choose.
Adjustable precision
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Private and free
Everything runs locally in your browser — no upload, no account, no limit on conversions.
Common use cases
- Converting a Rankine measurement to kelvin for a spec, listing, or report.
- Checking Rankine↔kelvin figures while comparing products, datasets, or documentation.
- Learning the Rankine-to-kelvin relationship from the worked formula and the common-value table.
Frequently asked questions
How many kelvin are in a Rankine?
Use the formula K = °R × 0.555556. For example, 25 °R = 13.8889 K.
What is the formula to convert degrees Rankine to kelvin?
K = °R × 0.555556. This tool applies it automatically and shows a worked example: 25 °R = 13.8889 K.
Can it convert kelvin back to degrees Rankine?
Yes. Press the swap button, or type into the kelvin field, and the tool converts kelvin to degrees Rankine using the inverse of the same relationship.
Is the conversion accurate?
It uses the standard temperature definition, not a rounded approximation, so results are exact to the number of decimal places you select.
Does this work offline and stay private?
Yes. The converter is a browser-side script with no network calls: your values are never uploaded, and once the page has loaded it keeps working without a connection.
