Frequently asked questions

What is the Newton scale?

The Newton scale (°N) is a temperature scale invented by Isaac Newton around 1700. It sets 0 °N as the freezing point of water and 33 °N as the boiling point.

How do I convert from Newton to Fahrenheit?

Use the inverse formula: °F = (°N × 60 / 11) + 32.

Is the Newton scale still used?

No, it is mostly of historical interest. The Celsius and Fahrenheit scales are used in everyday life.

Formulas

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

Fahrenheit to Newton

°N = (°F − 32) × 11 / 60

The Newton scale divides the range between freezing and boiling of water into 33 units, while Fahrenheit uses 180 units. So each Newton degree equals 180/33 = 60/11 Fahrenheit degr

Example:

Input: °F = 98.6

Calculation: (98.6 − 32) × 11 / 60 = 66.6 × 11 / 60

Result: ≈ 12.21 °N

Tips and common mistakes

Tips

  • Remember the freezing point of water is 0 °N and boiling is 33 °N.
  • For quick mental estimates, multiply the Fahrenheit difference from 32 by 0.1833 (which is 11/60).
  • Use the inverse formula to check your conversion.

Common Mistakes to Avoid

  • Forgetting to subtract 32 before multiplying.
  • Using 33/180 instead of 11/60 (they are equivalent, but 11/60 is simpler).
  • Rounding intermediate steps too early, which can cause small errors.

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.
