Formula – How to calculate Delisle

To Delisle (°D)From Delisle (°D)
Celsius (°C)(100 – °C) x (3/2) = °D100 – (°De x (2/3)) = °C
Fahrenheit (°F)(212 – °F) x (5/6) = °D212 – (°De x 6/5) = °F
Kelvin (K)(373.15 – K) x (3/2) = °D373.15 – (°De x 2/3) = K
Rankine (°R)(671.67 – °R) x (5/6) = °D671/67 – (°De x 6/5) = °R
Rømer (°Rø)(60 – °Rø) x (20/7) = °D60 – (°De x 7/20) = °Rø
Réamur (°Ré)(80 – °Ré) x (15/8) = °D80 – (°De x (8/15)) = °Ré
Newton (°N)(33 – °N) x (50/11) = °D33 – (°De x 11/50) = °N

What is the Delisle temperature scale?

Delisle is a temperature scale invented in 1732.

The Delise scale used the boiling point of water as 0°De. The freezing point of water is 150°D. Unlike all other temperature scales (except for Celsius as originally proposed, which originally had a boiling point of 0° and a freezing point of 100°), a higher temperature number means colder, and a lower temperature number means warmer.
