(373.15 - kelvin) * 1.5Preguntas frecuentes
What is the Delisle scale?
The Delisle scale (°De) is a temperature scale invented by Joseph-Nicolas Delisle in 1732. It sets the boiling point of water at 0 °De and the freezing point at 150 °De, so higher Delisle values mean colder temperatures.
How do I convert from Delisle back to Kelvin?
Use the inverse formula: Kelvin = 373.15 - (Delisle / 1.5). For example, 0 °De equals 373.15 K (boiling point of water).
Why is the conversion factor 1.5?
The Delisle scale divides the interval between boiling and freezing (373.15 K - 273.15 K = 100 K) into 150 degrees. So 1 °De corresponds to 100/150 = 2/3 K, meaning 1 K equals 1.5 °De.

Kelvin to Delisle
Subtract the Kelvin temperature from the boiling point of water (373.15 K) and multiply by 1.5 to get degrees Delisle.
Example:
Input: K = 300
Calculation: (373.15 - 300) × 1.5
Result: ≈ 109.73 °De
Casos de uso reales

Historical temperature conversion
Convert modern Kelvin measurements to the historical Delisle scale for educational or archival purposes.
Example: Converting 300 K to 109.73 °De
Understanding temperature scales
Compare how different scales represent the same physical temperature, especially the inverted nature of Delisle.
Example: Water boils at 0 °De and freezes at 150 °De
Science education
Teach students about temperature conversion and the relationship between absolute and historical scales.
Example: Absolute zero (0 K) equals 559.73 °De
Consejos y errores comunes
Tips
- Remember that Delisle is inverted: higher °De means colder.
- Kelvin is an absolute scale, so it never goes below 0.
- For quick mental estimates, remember that 373.15 K is boiling point (0 °De) and 273.15 K is freezing (150 °De).
- Use the formula in reverse to convert from Delisle to Kelvin.
Common Mistakes to Avoid
- Forgetting to subtract from 373.15 instead of adding.
- Using 273.15 as the reference point instead of 373.15.
- Confusing the direction: higher Kelvin gives lower Delisle.
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.
