Newton to Fahrenheit (°N to °F)
1 degree Newton equals 37.45454545 degrees Fahrenheit.
How to convert degrees Newton to degrees Fahrenheit
Converting degrees Newton to degrees Fahrenheit is not a simple multiplication, so use the formula below.
°F = °N × 5.454545455 + 32
Example: 10 degrees Newton = 86.54545455 degrees Fahrenheit.
Temperature scales have different zero points, so converting is not just multiplication. Differences in degrees convert differently from absolute readings.

Degree Newton (°N)
A scale devised by Isaac Newton around 1700 in which water freezes at 0° and boils at 33°. It is the ancestor of the modern temperature scales but was never widely adopted.
Isaac Newton described this temperature scale in an unsigned paper titled Scala graduum Caloris, printed in the Philosophical Transactions in 1701. His thermometer used linseed oil, whose volume changes with heat. He took the zero point from the heat of winter air at which water starts to freeze, and he put the point at which water begins to boil at 33. Other fixed points in his table included contact with the human body at 12, and various melting points for metals such as lead at 96 and bismuth at 81, with a bright glowing iron at 192.
Newton's table was a pioneering attempt to tie a numerical scale to reproducible physical events, and it appeared at about the same time as the scale of Ole Rømer. Because his reference points do not line up neatly, no single conversion is exact. Using water's boiling point gives about 3.03 degrees Celsius per degree Newton, while the body-temperature mark implies about 3.08. The figure used here is the boiling-point version, 100/33 kelvin per degree, with 0 N at 273.15 K. The scale never entered regular use and is now only a historical curiosity.
0 degrees Newton = 273.15 kelvins (exactly).

Degree Fahrenheit (°F)
The temperature scale used in the United States and a few other countries: water freezes at 32 °F and boils at 212 °F. Proposed by Daniel Gabriel Fahrenheit in 1724.
Daniel Gabriel Fahrenheit, who lived from 1686 to 1736, proposed his scale in 1724. His zero came from a freezing mixture of ice, water and ammonium chloride (or sea salt), which holds a stable temperature, and his upper reference of about 96 was his estimate of human body temperature. His own letters say he built on Ole Rømer's scale. Accounts of how he picked zero differ, and a popular German story that it was the coldest winter day in his home city of Danzig has failed verification.
Around 1776 to 1777 a Royal Society committee led by Henry Cavendish fixed water's freezing point at 32 degrees and its boiling point at 212, exactly 180 degrees apart, which moved body temperature to about 98.6. Today the scale is defined through the kelvin; NIST puts absolute zero at minus 459.67 degrees Fahrenheit. It remains in everyday use in the United States and its territories, Palau, the Federated States of Micronesia, the Marshall Islands and the Cayman Islands. A comfortable room is around 70 degrees, which is about 21 degrees Celsius.
0 degrees Fahrenheit = 255.3722222 kelvins (approximately).
