Units explained
Planck Temperature
The Planck temperature (T_P) is the natural unit of temperature, about 1.416784×10³² kelvins, constructed purely from the fundamental constants ħ, c, G, and k. It is widely regarded as the highest temperature at which known physics remains meaningful.
Arises from Max Planck's 1899 system of natural units, which combines the speed of light, the gravitational constant, the reduced Planck constant, and the Boltzmann constant into universal base quantities independent of any human artifact.
Cosmology and quantum-gravity research, where it marks the temperature of the universe roughly one Planck time after the Big Bang. No laboratory process approaches even a trillionth of a trillionth of it.
Defined within Max Planck's natural-unit system proposed in Germany in 1899; the modern recommended value (1.416784×10³² K) is maintained by the CODATA fundamental-constants adjustment.
Newton
The degree Newton (°N) sets the freezing point of water at 0 °N and the boiling point at 33 °N, making one degree Newton equal to exactly 100/33 kelvins (about 3.03 K) — the largest degree of any classic scale.
Devised by Isaac Newton using linseed-oil thermometers and a ladder of everyday reference points such as melting snow and the heat of the human body, published anonymously around 1701.
Never adopted for practical measurement, but historically important: Newton's idea of anchoring a scale to two reproducible fixed points directly influenced Celsius's centigrade approach four decades later.
Published by Isaac Newton in the Philosophical Transactions of the Royal Society in London, around 1701.
Planck Temperature to Newton conversion formula
Note: this conversion uses the CODATA recommended value of the Planck temperature (1.416784×10³² K), which carries a small experimental uncertainty from the gravitational constant G.
The exact relationship between planck temperatures and degrees newton:
To convert planck temperatures to degrees newton, multiply the value by 4.675387e+31, then subtract 90.1395. To reverse, multiply the value by 2.13886e-32, then add 1.927958e-30.
Reference anchors: water freezes at 1.927958e-30 T_P = 0 °N and boils at 2.633782e-30 T_P = 33 °N (at standard atmospheric pressure).

Step-by-step: convert planck temperatures to degrees newton
- Write down the temperature in planck temperatures (T_P).
- Multiply the value by 4.675387e+31, then subtract 90.1395.
- The result is the same temperature expressed in degrees newton (°N).
- To reverse, multiply the value by 2.13886e-32, then add 1.927958e-30 — or open the Newton to Planck Temperature converter.
Worked examples
Example 1 — Convert 1 T_P to °N:
(1 × 4.675387e+31) − 90.1395 = 4.675387e+31 °N
Example 2 — Convert 100 T_P to °N:
(100 × 4.675387e+31) − 90.1395 = 4.675387e+33 °N
