🌡️ Newton to Celsius Converter
Convert temperatures from Newton (°N) to Celsius (°C). The Newton scale was invented in 1701 by Sir Isaac Newton and is a precursor to the Celsius scale. It uses the freezing point of water as 0 °N and the boiling point as 33 °N.
What Is the Newton Scale?
The Newton scale (°N) is a temperature scale devised by Sir Isaac Newton in 1701. It is one of the earliest attempts to create an objective temperature scale and is a direct precursor to the modern Celsius scale.
Key characteristics of the Newton scale:
- Zero point: 0 °N = the freezing point of water (0 °C).
- Boiling point: 33 °N = the boiling point of water (100 °C).
- Unit size: 1 Newton degree = 100/33 ≈ 3.03 degrees Celsius.
- Conversion formula: °C = °N × 100/33.
Newton used linseed oil as his thermometric fluid and measured its volume change with temperature. He set 0 °N as "the heat of air in winter at which water begins to freeze" and noted the boiling point of water as 33 °N.
The scale was quickly superseded by the Celsius scale, which uses the same reference points but divides the interval into 100 degrees. Today, the Newton scale is largely obsolete but remains of historical interest.
How to Convert Newton to Celsius
The formula to convert Newton to Celsius is:
°C = °N × 100/33
or °C = °N × 3.03030303
This formula works because:
- 0 °N corresponds to the freezing point of water (0 °C).
- 33 °N corresponds to the boiling point of water (100 °C).
- Each Newton degree is equivalent to 100/33 degrees Celsius.
For example, to convert 33 °N (the boiling point of water) to Celsius:
°C = 33 × 100/33
°C = 33 × 3.03030303
°C = 100 °C
To convert 0 °N (the freezing point of water) to Celsius:
°C = 0 × 100/33
°C = 0 °C

❓ Newton to Celsius FAQ
What is the formula to convert Newton to Celsius?
The formula is °C = °N × 100/33 or °C = °N × 3.03030303.
What is the Newton scale used for?
The Newton scale was invented by Sir Isaac Newton in 1701 and is one of the earliest objective temperature scales. It was used for practical measurements but has since been replaced by the Celsius scale.
What is the relationship between the Newton and Celsius scales?
Both scales use the same reference points: 0 °N = 0 °C (water freezes) and 33 °N = 100 °C (water boils). The Newton scale divides this interval into 33 degrees, while Celsius divides it into 100 degrees.
What is absolute zero in Newton degrees?
Absolute zero (0 K, −273.15 °C) is approximately −90.14 °N.
What is the boiling point of water in Newton degrees?
The boiling point of water is 33 °N (100 °C).
What is the freezing point of water in Newton degrees?
The freezing point of water is 0 °N (0 °C).
Who invented the Newton scale?
The Newton scale was invented by Sir Isaac Newton (1643–1727) in 1701.
Is the Newton scale still used today?
The Newton scale is largely obsolete for everyday use but is still referenced in historical studies and some textbooks.
