Newton to Delisle Temperature Conversion

The Newton and Delisle scales are historical temperature scales, offering valuable insights into the evolution of thermometry. While less common today, understanding their conversions is crucial for historical research, scientific data analysis, and a deeper appreciation of temperature measurement.

Understanding the Scales

Newton Scale: Developed by Sir Isaac Newton in 1701, this descending scale defines the freezing point of water as 0°N and the boiling point as 33°N.

Delisle Scale: Invented by Joseph-Nicolas Delisle in 1732, this also a descending scale, with the boiling point of water at 0°D and the freezing point at 150°D.

Conversion Formula

The formula to convert Newton to Delisle is:

Delisle (°D) = 150 - (Newton (°N) * 150/33)

Example Calculation

Let's convert 10°N to Delisle:

  1. Delisle = 150 - (10N * 150/33)
  2. Delisle = 150 - (10 * 4.545) = 150 - 45.45 = 104.55°D

Therefore, 10 degrees Newton is equivalent to 104.55 degrees Delisle.

Significance of Conversion

Understanding this conversion is valuable for:

  • Historical Research:** Analyzing historical scientific data recorded in these units.
  • Scientific Accuracy:** Ensuring precise data interpretation across different temperature scales.
  • Educational Enrichment:** Enhancing our understanding of the historical evolution of temperature measurement.
