# Celsius to Newton (°C to °N)

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

To convert Celsius to the Newton temperature scale, multiply by 33/100. Isaac Newton's scale sets water's freezing point at 0°N and boiling point at 33°N. This conversion is of purely historical interest, as the Newton scale has no modern applications.

## Formula

°N = °C × 33/100

## Units

### 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.

### 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.

## Background

Room temperature of 20°C equals 6.6°N. Body temperature (37°C) is about 12.2°N. Boiling water (100°C) is 33°N. Newton's scale preceded both Fahrenheit and Celsius, making it one of the earliest quantitative temperature scales in history.

## Good to Know

Newton's temperature scale predates both Fahrenheit (1724) and Celsius (1742). It is one of the earliest attempts to assign numbers to temperature, and studying it helps appreciate how temperature measurement evolved.

## FAQ

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

The formula is: °N = °C × 33/100. For example, 50°C × 33/100 = 16.5°N. The Newton scale compresses the 0-100 Celsius range into 0-33.

### What is 37°C (body temperature) in Newton?

37°C equals approximately 12.21°N. Newton originally set body temperature at 12°N on his scale.

### Is the Newton temperature scale related to Isaac Newton?

Yes, Isaac Newton devised this scale around 1700-1701. He used linseed oil as the thermometric fluid. The scale should not be confused with the newton (N), the SI unit of force.

## Non-Frequently Asked Questions

### Did Isaac Newton really make a temperature scale?

Yes, around 1700. He set 0 at the freezing point of water and 33 at the boiling point. Why 33? Because he calibrated it using linseed oil and the number just worked out that way. Even Newton sometimes shrugged and said 'good enough.'
