# Newton to Celsius (°N to °C)

Source: https://www.unitconvertercalculator.com/temperature/newton-scale-to-celsius/

To convert Newton scale to Celsius, multiply by 100/33. Isaac Newton's temperature scale, devised around 1701, sets freezing at 0°N and boiling at 33°N. This conversion translates Newton's historical measurements into modern Celsius equivalents.

## Formula

°C = °N × 100/33

## Units

### 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.

### Celsius (°C)

A metric temperature scale where 0°C is the freezing point and 100°C is the boiling point of water. Used worldwide except in the US.

## Background

Newton body temperature (12°N) equals about 36.4°C. Boiling water at 33°N equals 100°C. Newton's scale, though never widely adopted, influenced the development of both the Fahrenheit and Celsius scales.

## Good to Know

Newton published his temperature scale anonymously in 1701. Its main legacy is historical: it predated and influenced both Fahrenheit and Celsius, making it a key stepping stone in the history of thermometry.

## FAQ

### What is the formula for Newton to Celsius?

The formula is: °C = °N × 100/33. For example, 12°N: 12 × 100/33 = 36.36°C.

### What is 33°N in Celsius?

33°N equals exactly 100°C - the boiling point of water on Newton's scale.

### Why did Newton choose 33 for boiling?

Newton may have preferred 33 because it is close to 32 (a power of 2) and has useful divisors. He also wanted body heat to fall near 12°, another highly divisible number.

## Non-Frequently Asked Questions

### Is the Newton temperature scale named after the fig cookie?

No. It is named after Sir Isaac Newton, who proposed it around 1700. He set 0 at the freezing point of water and 33 at the boiling point, because apparently even Newton could not always pick round numbers. Fig Newtons are named after Newton, Massachusetts, not the scientist.
