Cómo funciona

  1. 1

    Enter the temperature in Rømer degrees.

  2. 2

    Subtract 7.5 from the Rømer value.

  3. 3

    Multiply the result by 40/21.

  4. 4

    Add 273.15 to get Kelvin.

(roemer - 7.5) * 40 / 21 + 273.15

Preguntas frecuentes

Fórmulas

Las matemáticas detrás de esta calculadora, escritas para que puedas verificar el resultado.

Rømer to Kelvin

K = (°Rø − 7.5) × 40/21 + 273.15

The Rømer scale sets freezing of water at 7.5 and boiling at 60. The conversion adjusts for the offset and scaling.

Example:

Input: °Rø = 0

Calculation: (0 − 7.5) × 40/21 + 273.15

Result: 258.86 K

Casos de uso reales

Dónde aparece este cálculo en la vida cotidiana.

Historical temperature records

Convert old temperature readings recorded in Rømer to modern Kelvin for scientific comparison.

Example: A 1700s record of 10 °Rø becomes 278.10 K.

Education

Teach temperature scale conversions and the relationships between different units.

Example: Show that 7.5 °Rø equals 273.15 K.

Cross-referencing data

When working with mixed historical and modern data, convert all values to a common scale.

Example: Convert a series of Rømer measurements to Kelvin for analysis.

Consejos y errores comunes

Tips

  • Remember that 0 °Rø is about 258.86 K, which is well below freezing.
  • Use the formula directly for any Rømer value, including negative ones.
  • Double-check your arithmetic when subtracting 7.5, as it is a common source of error.

Common Mistakes to Avoid

  • Forgetting to subtract 7.5 before scaling.
  • Using 273 instead of 273.15 for the Kelvin offset.
  • Mixing up the order of operations: multiply before adding.

Supuestos y limitaciones

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