Delisle in Rankine FAQ

• Wie rechnet man Delisle in Rankine um?

  Formel: R = 671.67 - De x 6/5. 0 Delisle (boiling) = 671.67 degrees Rankine, 150 Delisle (freezing) = 491.67 degrees Rankine.

• Warum läuft die Delisle-Skala rückwärts?

  Delisle maß, wie weit unter dem Siedepunkt eine Temperatur lag. Höhere Zahlen bedeuteten weiter vom Siedepunkt, also kälter.

• Wann muss man Delisle in Rankine umrechnen?

  Bei der Interpretation historischer russischer Wissenschaftsaufzeichnungen aus dem 18.-19. Jahrhundert.

Nicht häufig gestellte Fragen zu Delisle in Rankine

Fragen, die niemand stellen sollte - aber jemand hat es getan.

• Is the Delisle-to-Rankine conversion the most obscure temperature conversion possible?

  It is certainly among the most niche. Delisle is a defunct 18th-century Russian scale. Rankine is a specialized American engineering scale. The number of people who have ever needed to convert between them directly could probably fit in a small room - and they would all be either historians of Russian science or unusually thorough textbook authors.

• Do Delisle and Rankine have anything in common?

  Both are related to better-known scales: Delisle to Celsius (inverted), Rankine to Fahrenheit (absolute). Both were created for scientific purposes. And both are now used primarily in conversion tables rather than in active measurement. They are the supporting actors of thermometry - important for completeness, rarely the stars.

• If a Russian scientist in 1750 met an American engineer in 1960, could they agree on a temperature?

  With great difficulty. The Russian would say '100 Delisle' (33.3 degrees C). The American would say '92 Fahrenheit' (33.3 degrees C). Neither would recognize the other's scale. They would need Celsius as a shared translator - which is exactly why Celsius eventually won as the international standard.
