Frequently asked questions

What is the Newton scale?

The Newton scale (°N) was proposed by Isaac Newton in 1701. It sets 0°N as the freezing point of water and 33°N as the boiling point, so each degree Newton equals 100/33 °C.

How do I convert Celsius back to Newton?

Multiply the Celsius temperature by 33 and divide by 100. For example, 100°C × 33 / 100 = 33°N.

Is the Newton scale still used today?

No, it is mostly of historical interest. The Celsius and Fahrenheit scales are standard, but the Newton scale is sometimes used in physics history discussions.

Formulas

The math behind this calculator, written out so you can verify the result.

Newton to Celsius

°C = °N × (100 / 33)

Since 0°N equals 0°C and 33°N equals 100°C, the conversion factor is 100/33.

Example:

Input: °N = 16.5

Calculation: 16.5 × (100 / 33)

Result: 50°C

Real-world use cases

Where this calculation shows up in everyday life.

Historical temperature conversion

Convert temperatures recorded in Newton scale in old scientific documents to modern Celsius.

Example: A thermometer from 1700s reads 20°N; convert to Celsius.

Educational demonstrations

Teach students about temperature scales and linear conversions using a less common scale.

Example: Show that 33°N equals 100°C.

Tips and common mistakes

Tips

  • Remember the freezing and boiling points: 0°N = 0°C and 33°N = 100°C.
  • For quick mental estimates, 1°N is about 3.03°C.
  • Use the formula °C = °N × 3.0303 for approximate conversions.

Common Mistakes to Avoid

  • Using 33 as a divisor instead of multiplying by 100/33.
  • Forgetting that the Newton scale has 33 divisions between freezing and boiling, not 100.
  • Confusing Newton with Réaumur, which uses 80 divisions.

Assumptions and limitations

  • Use the stated inputs and units.
  • Results are estimates for planning and education.
  • Check measurements and source data before making an important decision.
