Frequently asked questions

What is the freezing point of water in Rømer?

The freezing point of water is 7.5 °Rø, which converts to 32 °F.

How do I convert Fahrenheit back to Rømer?

Use the inverse formula: °Rø = (°F - 32) × 7/24.

Is the Rømer scale still used today?

No, it is mostly of historical interest, but it is the basis for the Fahrenheit scale.

Formulas

The math behind this calculator, written out so you can verify the result.

Rømer to Fahrenheit

°F = °Rø × (24/7) + 32

Each degree Rømer equals 24/7 degrees Fahrenheit, and the scale is offset by 32°F.

Example:

Input: °Rø = 7.5

Calculation: 7.5 × (24/7) + 32

Result: 57.71 °F

Tips and common mistakes

Tips

  • Remember that 0 °Rø is about -22.86 °F.
  • Use the inverse formula for reverse conversion.
  • For quick mental estimates, multiply by 3.43 and add 32.
  • Check your result with known points: 7.5 °Rø = 32 °F.

Common Mistakes to Avoid

  • Forgetting to add 32 after multiplying.
  • Using 7/24 instead of 24/7.
  • Confusing Rømer with Réaumur.

Assumptions and limitations

  • Use the stated inputs and units.
  • Results are estimates for planning and education.
  • Check measurements and source data before making an important decision.
