R = F + 459.67。支持华氏度、兰氏度、摄氏度、开尔文互算。R = F + 459.67. Units: Fahrenheit, Rankine, Celsius, Kelvin.
如何使用「华氏度 ↔ 兰氏度」？How do I use the Fahrenheit to Rankine tool?
在「华氏度 ↔ 兰氏度」中输入数值并选择原单位，表格会同时列出换算到所有其他单位的结果，可一键复制。Enter a value in the Fahrenheit to Rankine and choose the source unit; the table shows the value in every other unit at once, ready to copy.
兰氏度是什么？What is the Rankine scale?
兰氏度是以华氏度为刻度的绝对温标：0 °R 是绝对零度，每度与华氏度一样大，所以 °R = °F + 459.67。美国部分工程热力学计算会用到。Rankine is an absolute scale with Fahrenheit-sized degrees: 0 °R is absolute zero and °R = °F + 459.67. It appears in some US engineering thermodynamics.
有哪些选项可以调整？What options can I adjust?
「华氏度 ↔ 兰氏度」的设置：「数值」默认 1。每次生成结果都按当前设置处理。Settings in the Fahrenheit to Rankine — "Value" default 1. The result always uses the current settings.
