'''Skala Rømer''' adalah skala [[suhu]] yang tidak digunakan lagi, dinamai menurut [[astronom]] [[Denmark]] [[Ole Rømer|Ole Christensen Rømer]] yang mengusulkannya pada [[1701]].
 
Dalam skala ini, nol adalah titik beku [[brine]] dan titik didih [[air]] adalah 60 derajat. Rømer kemudian mengamati bahwa titik beku air adalah 7,5 derajat, dan ini juga diambil sebagai titik rujukan ketiga. Jadi satuan skala ini, satu derajat Rømer, adalah 40/21 [[kelvin]] (atau derajat [[Celsius]]). Lambang satuan ini biasanya '''°R''', namun untuk menghindari kerancuan dengan [[skala Rankine]] digunakan '''°Rø'''.
In this scale, the zero was initially set using freezing [[brine]]. The boiling point of [[water]] was defined as 60 degrees. Rømer then saw that the freezing point of water fell at roughly one eighth of that value (7.5 degrees), so he used that value as the other fixed point. Thus the [[Units of measurement|unit]] of this scale, a Rømer degree, is 40/21 of a [[kelvin]] (or of a [[Celsius]] degree). The symbol is sometimes given as '''°R''', but since that is also sometimes used for the [[Rankine]] scale, the other symbol '''°Rø''' is to be preferred. The name should not be confused with [[Réaumur]].

'''Rømer''' is a disused [[temperature]] scale named after the [[Denmark|Danish]] [[astronomer]] [[Ole Rømer|Ole Christensen Rømer]], who proposed it in [[1701]].

The name should not be confused with [[Réaumur]].
 
[[Daniel Gabriel Fahrenheit]] learned of Rømer's work and visited him in [[1708]]; he improved on the scale, increasing the number of divisions by a factor of four and eventually establishing what is now known as the [[Fahrenheit]] scale, in [[1724]].
