Comment ça marche

  1. 1

    Enter the temperature in degrees Delisle.

  2. 2

    Multiply the Delisle value by 2/3.

  3. 3

    Subtract that result from 373.15.

  4. 4

    The result is the temperature in Kelvin.

373.15 - (delisle * 2 / 3)

Questions fréquentes

What is the Delisle scale?

The Delisle scale (°De) is an obsolete temperature scale where water boils at 0 degrees and freezes at 150 degrees. It decreases as temperature increases.

Why is the formula 373.15 - (Delisle × 2/3)?

Because 0 °De corresponds to 373.15 K (boiling point of water) and 150 °De corresponds to 273.15 K (freezing point). The scale is inverted and has a slope of 2/3 K per °De.

Can I convert Kelvin to Delisle with this calculator?

No, this calculator only converts from Delisle to Kelvin. For the reverse, use the formula: Delisle = (373.15 - Kelvin) × 1.5.

Delisle to Kelvin

K = 373.15 - (De × 2/3)

Kelvin equals 373.15 minus two-thirds of the Delisle value.

Example:

Input: De = 150

Calculation: 373.15 - (150 × 2/3) = 373.15 - 100

Result: 273.15 K

Cas d'utilisation réels

Où ce calcul apparaît dans la vie quotidienne.

Historical temperature conversion

Convert old scientific records or literature that used the Delisle scale.

Example: A 1700s thermometer reading of 100 °De.

Educational demonstrations

Teach students about temperature scales and their relationships.

Example: Show that 0 °De is boiling and 150 °De is freezing.

Cross-checking conversions

Verify conversions between Delisle and other scales like Celsius or Fahrenheit.

Example: Convert 50 °De to Kelvin and then to Celsius.

Conseils et erreurs courantes

Tips

  • Remember that Delisle is an inverted scale: higher Delisle means lower temperature.
  • For quick mental estimates, each 1 °De change equals about 0.667 K change.
  • Use the freezing and boiling points as anchors: 150 °De = 273.15 K, 0 °De = 373.15 K.

Common Mistakes to Avoid

  • Forgetting to invert the scale and adding instead of subtracting.
  • Using 273.15 instead of 373.15 as the base for 0 °De.
  • Mixing up the factor: it's 2/3, not 3/2.

Hypothèses et limites

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