Units explained
Millikelvin
One millikelvin (mK) is one thousandth of a kelvin (10⁻³ K), measured upward from absolute zero.
Formed with the SI prefix 'milli-' (from Latin 'mille', a thousand) applied to the kelvin base unit.
Cryogenics and low-temperature physics — the dilution refrigerators that cool superconducting quantum computers operate at roughly 10–20 mK.
The milli- prefix belongs to the original metric system of 1795 and was carried into the SI in 1960; the kelvin became an SI base unit in 1954.
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.
Millikelvin to Newton conversion formula
The exact relationship between millikelvins and degrees newton:
To convert millikelvins to degrees newton, subtract 273150 from the value, then multiply by 0.00033. To reverse, multiply the value by 3030.30303, then add 273150.
Reference anchors: water freezes at 273150 mK = 0 °N and boils at 373150 mK = 33 °N (at standard atmospheric pressure).

Step-by-step: convert millikelvins to degrees newton
- Write down the temperature in millikelvins (mK).
- Subtract 273150 from the value, then multiply by 0.00033.
- The result is the same temperature expressed in degrees newton (°N).
- To reverse, multiply the value by 3030.30303, then add 273150 — or open the Newton to Millikelvin converter.
Worked examples
Example 1 — Convert 1 mK to °N:
(1 − 273150) × 0.00033 = -90.13917 °N
Example 2 — Convert 100 mK to °N:
(100 − 273150) × 0.00033 = -90.1065 °N
