Use a unidade ao lado de cada resultado para a identificar.<\/li>\n<\/ol>\n<p>Para come\u00e7ar com uma unidade diferente, use o <a href=\"https:\/\/wpcalc.com\/pt\/conversores\/fahrenheit\/\">conversor de Fahrenheit<\/a>, o <a href=\"https:\/\/wpcalc.com\/pt\/conversores\/kelvin\/\">conversor de Kelvin<\/a> ou o <a href=\"https:\/\/wpcalc.com\/pt\/conversores\/celsius\/\">conversor de Celsius<\/a>.<\/p>\n<h2>O que uma convers\u00e3o de Rankine lhe diz<\/h2>\n<p>Rankine \u00e9 uma escala de temperatura absoluta: 0 \u00b0R \u00e9 o zero absoluto, o limite te\u00f3rico inferior da temperatura termodin\u00e2mica. Uma varia\u00e7\u00e3o de um grau Rankine tem o mesmo tamanho que uma varia\u00e7\u00e3o de um grau Fahrenheit. Essa combina\u00e7\u00e3o torna Rankine \u00fatil em certos c\u00e1lculos de engenharia que usam intervalos de temperatura do tamanho dos de Fahrenheit, mas exigem uma temperatura absoluta.<\/p>\n<p>Kelvin tamb\u00e9m \u00e9 uma escala absoluta, mas os seus incrementos t\u00eam o mesmo tamanho que os graus Celsius. Porque 1 K equivale a 1,8 \u00b0R como intervalo de temperatura, converter uma temperatura absoluta de Rankine para kelvin exige dividir por 1,8. Nem kelvin nem Rankine precisam de um deslocamento (offset) para essa convers\u00e3o. Por outro lado, converter Rankine para Fahrenheit exige subtrair 459,67, porque as duas escalas t\u00eam pontos zero diferentes.<\/p>\n<p>Celsius e Fahrenheit s\u00e3o muitas vezes mais f\u00e1ceis de interpretar como temperaturas do dia a dia. Por exemplo, o valor padr\u00e3o de 500 \u00b0R corresponde a cerca de 4,63 \u00b0C ou 40,33 \u00b0F: uma temperatura acima do ponto de congelamento da \u00e1gua \u00e0 press\u00e3o atmosf\u00e9rica padr\u00e3o. Os resultados em Newton, Delisle, R\u00e9aumur e R\u00f8mer expressam essa mesma temperatura em escalas menos utilizadas. Delisle varia no sentido oposto ao de Celsius, pelo que uma temperatura mais quente tem uma leitura de Delisle mais baixa.<\/p>\n<h2>Pressupostos e dicas pr\u00e1ticas<\/h2>\n<ul>\n<li>Introduza uma temperatura absoluta, n\u00e3o uma diferen\u00e7a de temperatura. Para converter um intervalo de 10 \u00b0R, por exemplo, use 10 \u00b0F ou 10\/1,8 K como intervalo; n\u00e3o aplique os deslocamentos usados para temperaturas absolutas.<\/li>\n<li>A entrada come\u00e7a em 0 \u00b0R. Valores negativos em Rankine est\u00e3o abaixo do zero absoluto e n\u00e3o s\u00e3o temperaturas termodin\u00e2micas ordin\u00e1rias v\u00e1lidas.<\/li>\n<li>O arredondamento pode fazer com que um resultado apresentado difira ligeiramente de um c\u00e1lculo manual. A calculadora tamb\u00e9m usa aproxima\u00e7\u00f5es decimais nas f\u00f3rmulas de Newton e R\u00f8mer, portanto, mantenha d\u00edgitos extra ao verificar os passos intermedi\u00e1rios.<\/li>\n<li>Para contexto, a \u00e1gua congela a 491,67 \u00b0R e ferve a 671,67 \u00b0R \u00e0 press\u00e3o atmosf\u00e9rica padr\u00e3o. O ponto de ebuli\u00e7\u00e3o varia com a press\u00e3o; estes s\u00e3o pontos de refer\u00eancia, n\u00e3o limiares fixos para todos os locais.<\/li>\n<\/ul>\n<p>Se a sua fonte usar uma escala hist\u00f3rica, verifique a unidade antes de introduzir um valor aqui. Por exemplo, uma leitura em Delisle pertence a um <a href=\"https:\/\/wpcalc.com\/pt\/conversores\/delisle\/\">conversor de Delisle<\/a>, n\u00e3o ao campo de Rankine.
