About Converting Romers to Newtons
Romer and Newton are both historical temperature scales no longer in everyday use — this conversion is mainly useful for historical reference or comparing older scientific texts against each other.
Formula
Convert the source temperature to Kelvin, then convert Kelvin to the target scale.
Both scales are converted through Kelvin as a common absolute reference point.
Simple example
(0 − 32) × 5/9 = -4.714285714 °C
0 romers = -4.714285714 newtons.
Real-world example
(0 − 32) × 5/9 = -4.714285714 °C
0 romers = -4.714285714 newtons.

Frequently asked questions
How many newtons are in 1 romer?
1 romer equals -4.085714286 newtons, using the offset temperature formula rather than an estimate.
How do I convert romer to newton?
Use the formula shown above: it involves both a multiplication and an addition/subtraction because the two scales don't share a common zero point.
How do I convert newton back to romer?
Use the reverse factor: 1 newton equals 9.090909091 romers. You can also use the swap control in the converter above to flip the direction instantly.
What is a romer?
Romer (Ro) is a unit of temperature.
What is a newton?
Newton (N) is a unit of temperature.
Is the Romer to Newton conversion exact?
Yes. Both scales are formally defined relative to the Kelvin scale, so the conversion formula is exact — the only rounding involved is in how many decimal places you choose to display.
