61Réaumur scale — This article is about the temperature scale. For other uses, see Réaumur (disambiguation). Not to be confused with Rømer scale. Old thermometer in a pharmacy in Vienna showing average room temperature in Réaumur The Réaumur scale (°Ré, °Re, °R),… …
62Newton scale — Not to be confused with Newton (unit), the SI unit of force. Newton temperature conversion formulae from Newton to Newton Celsius [°C] = [°N] × 100⁄33 [°N] = [°C] × 33⁄100 Fahrenheit… …
63Negative temperature — In physics, certain systems can achieve negative temperatures; that is, their thermodynamic temperature can be a negative quantity. Negative temperatures can be expressed as negative numbers on the kelvin scale. Temperatures that are expressed as …
64Leiden scale — The Leiden scale was used to calibrate low temperature indirect measurements in the early twentieth century, by providing conventional values (in kelvins, then termed degrees Kelvin ) of helium vapour pressure. It was used below 183°C, the… …
65Delisle scale — Delisle temperature conversion formulae from Delisle to Delisle Celsius [°C] = 100 − [°De] × 2⁄3 [°De] = (100 − [°C]) × 3⁄2 Fahrenheit [°F] = 212 − [°De] × 6… …
66Degree (temperature) — For other uses, see Degree (disambiguation). The term degree is used in several scales of temperature. The symbol ° is usually used, followed by the initial letter of the unit, for example “°C” for degree(s) Celsius. A degree can be defined as a… …
67Rømer scale — Rømer is a disused temperature scale named after the Danish astronomer Ole Christensen Rømer, who proposed it in 1701. In this scale, the zero was initially set using freezing brine. The boiling point of water was defined as 60 degrees. Rømer… …
68absolute scale — noun a temperature scale that defines absolute zero as 0 degrees; water freezes at 273.16 degrees and boils at 373.16 degrees • Syn: ↑Kelvin scale • Hypernyms: ↑temperature scale * * * noun : a temperature scale that is based on absolute zero and …
69Normal human body temperature — 98.6 redirects here. For other uses, see 98.6 (disambiguation). Normal human body temperature, also known as normothermia or euthermia, is a concept that depends upon the place in the body at which the measurement is made, and the time of day and …
70Glass transition temperature — The glass transition temperature, T g, is the temperature at which an amorphous solid, such as glass or a polymer, becomes brittle on cooling, or soft on heating. More specifically, it defines a pseudo second order phase transition in which a… …
