How do I use this tool to convert Celsius to Rømer?

Enter the Celsius value (e.g., 25) and click 'Convert'. The tool applies the formula Rø = C × 21/40 + 7.5. For 25°C, the result is 20.625°Rø. You can also convert back by using the inverse.

Why would I need to convert Celsius to Rømer?

Although the Rømer scale is obsolete, it appears in historical scientific documents and old Danish/European weather records. Converting to Rømer helps researchers interpret archival temperature data without miscalculating the offset (7.5°Rø at freezing) and scale (60°Rø at boiling).

Does the conversion preserve decimal precision?

Yes, we keep up to 6 decimal places in the result. However, note that Rømer degrees are larger than Celsius degrees (1°Rø = 40/21°C), so a small Celsius change may become a fraction of a Rømer degree. Negative temperatures are handled exactly; no data is lost because both scales are linear.

Is Celsius to Rømer Converter free to use?

Yes, Celsius to Rømer Converter on LetsConvert is 100% free with no registration or hidden fees required.

Are my uploaded files safe and secure?

Yes! File privacy and security are guaranteed. Basic conversions run locally in your browser. Files sent for server processing are automatically deleted within 1 hour.

Does this converter work on mobile phones and tablets?
