How do you convert Newton to Delisle?

Use the formula De = (33 - N) x 50/11. At the freezing point of water: 0 N = 150 De. At the boiling point: 33 N = 0 De.

When would you need to convert Newton to Delisle?

This conversion is needed when interpreting historical scientific records, comparing temperature data across different measurement traditions, or completing engineering calculations that mix temperature scales from different national standards.

What are the key reference points for both scales?

Water freezes at 0 N = 150 De. Water boils at 33 N = 0 De. These two fixed points anchor both scales and provide easy verification of any conversion calculation.

Newton to Delisle (°N to °De) Converter

1 °N = 145.4545 °De

1 Newton equals 145.4545 Delisle (1 °N = 145.4545 °De). Convert Newton to Delisle with formula, table, and examples.

To convert Newton to Delisle, use the formula: De = (33 - N) x 50/11. The Newton scale is Isaac Newton's rarely-used temperature scale, while the Delisle scale is the inverted 18th-century Russian scale. Water freezes at 0 degrees N (150 De) and boils at 33 degrees N (0 De).

Good to Know About Newton to Delisle Conversion

The history of temperature measurement is the history of scientific collaboration and competition across borders. The Newton scale (barely adopted beyond his laboratory) and the Delisle scale (used in Russia) represent different national contributions to solving the same fundamental problem: how to assign numbers to the sensation of hot and cold.

Newton to Delisle: What You Need to Know

The Newton scale was created by Isaac Newton, around 1700, barely adopted beyond his laboratory. The Delisle scale was created by Joseph-Nicolas Delisle, French astronomer, 1732, used in Russia. Converting between them bridges different eras and different measurement philosophies in the history of thermometry.

What is a Newton? °N

A temperature scale devised by Isaac Newton around 1700. Water freezes at 0 °N and boils at 33 °N. Not to be confused with the newton unit of force.

What is a Delisle? °De

A historical inverted temperature scale invented by Joseph-Nicolas Delisle in 1732. Water boils at 0 °De and freezes at 150 °De. Higher numbers mean colder temperatures.

Non-Frequently Asked Questions About Newton to Delisle

Questions nobody should ask - but someone did.

Almost certainly. Newton invented calculus, discovered the laws of motion and gravity, designed a reflecting telescope, and explained the spectrum of light. His temperature scale, where water boils at 33 degrees, is barely a footnote. It is the one Newton creation that even Newton enthusiasts tend to forget.
Newton calibrated his scale using linseed oil and other substances, placing human body heat at 12 degrees and water boiling at 33 degrees. The choice was practical for his experiments but produced an awkwardly narrow range. The 0-33 span for liquid water compares poorly to Celsius's cleaner 0-100 range.
The physics would be identical - nature does not change with the scale. But every thermodynamics textbook would use different numbers. The ideal gas constant, Boltzmann constant, and Stefan-Boltzmann constant would all have different numerical values. The equations would work identically; only the numbers plugged in would change.
