Grado Fahrenheit
Le grado Fahrenheit es le unitate de temperatura proponite per Gabriel Fahrenheit in 1724, cuje scala fixa le zero e le cento in le temperaturas de congelation e evaporation del chloruro ammonic in aqua.
Le methodo de definition es similar a illo utilisate pro le scala Celsius, ben que illo se defini con le congelation e evaporation del aqua.
In le scala Fahrenheit, le puncto de fusion del aqua es 32 grados, e le de ebullition es 212 grados. Un differentia de 1,8 grados Fahrenheit equivale a un differentia de 1 grado Celsius.
Le formulas de conversion a grado Celsius e kelvin es:
°F = °C · (9/5) + 32; °C = (°F - 32) · 5/9 °F = K · (9/5) - 459,67; K = (°F + 459,67) · 5/9 Iste scala es actualmente utilisate in alcun paises anglosaxone, in particular le Statos Unite de America.
Pro uso scientific se applica un scala derivate, le scala de Rankine, que ha le 0 al zero absolute, de forma similar a lo que occurre inter le scalas Kelvin e Celsius.
Conversion
| Conversion de | Conversion a | Formula |
|---|---|---|
| Fahrenheit | Celsius | °C = (°F - 32) / 1.8 |
| Celsius | Fahrenheit | °F = °C × 1.8 + 32 |
| Kelvin | Fahrenheit | K = (°F + 459.67) / 1.8 |
| Fahrenheit | Kelvin | °F = K × 1.8 - 459.67 |
| Fahrenheit | Rankine | °Ra = °F + 459.67 |
| Rankine | Fahrenheit | °F = °Ra - 459.67 |
| Fahrenheit | Réaumur | °Ré = (°F - 32) / 2.25 |
| Réaumur | Fahrenheit | °F = °Ré × 2.25 + 32 |
