Units explained
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.
Nanokelvin
One nanokelvin (nK) is one billionth of a kelvin (10⁻⁹ K) above absolute zero.
Formed with the SI prefix 'nano-' (from Greek 'nanos', dwarf) applied to the kelvin base unit.
The realm of Bose–Einstein condensates: the first condensate was created at about 170 nK in 1995, among the coldest temperatures ever achieved anywhere in the universe.
The nano- prefix was adopted by the 11th CGPM in 1960 at the launch of the International System of Units.
Newton to Nanokelvin conversion formula
The exact relationship between degrees newton and nanokelvins:
To convert degrees newton to nanokelvins, multiply the value by 3.030303e+9, then add 273150000000. To reverse, subtract 273150000000 from the value, then multiply by 3.3e-10.
Reference anchors: water freezes at 0 °N = 2.7315e+11 nK and boils at 33 °N = 3.7315e+11 nK (at standard atmospheric pressure).

Step-by-step: convert degrees newton to nanokelvins
- Write down the temperature in degrees newton (°N).
- Multiply the value by 3.030303e+9, then add 273150000000.
- The result is the same temperature expressed in nanokelvins (nK).
- To reverse, subtract 273150000000 from the value, then multiply by 3.3e-10 — or open the Nanokelvin to Newton converter.
Worked examples
Example 1 — Convert 12.21 °N to nK (human body temperature):
(12.21 × 3.030303e+9) + 273150000000 = 3.1015e+11 nK
Example 2 — Convert 33 °N to nK (the boiling point of water):
(33 × 3.030303e+9) + 273150000000 = 3.7315e+11 nK
