How do I convert ROMER to DELISLE?

Enter the ROMER value in the source field (or choose ROMER from the dropdown). The tool instantly applies the formula °De = (60 − °Rø) × 20/7 and shows the equivalent DELISLE value. You can also paste multiple ROMER values for batch conversion and copy the DELISLE results in one click.

Why would I need to convert ROMER to DELISLE?

ROMER and DELISLE are historical temperature scales: ROMER was used in northern Europe, while DELISLE was adopted in Russia in the 18th century. Converting between them lets you compare old climate logs, recalibrate antique thermometers, or merge data into modern spreadsheets that expect a single scale.

Does the ROMER to DELISLE conversion preserve negative and decimal precision?

Yes. The conversion uses the exact linear relationship °De = (60 − °Rø) × 20/7 without rounding. Negative ROMER values become higher DELISLE values because the DELISLE scale is inverted; decimals are kept at full double-precision, so you can convert extreme temperatures (e.g., −100 °Rø → 457.142857 °De) without data loss.
