About Rankine

Rankine (°R) is an absolute temperature scale named after Scottish engineer William John Macquorn Rankine. Like Kelvin, it starts at absolute zero (0°R = -459.67°F = 0 K), but uses Fahrenheit-sized degree intervals instead of Celsius-sized ones. It's primarily used in engineering applications in the United States, particularly in thermodynamics and steam power calculations. For reference: water freezes at 491.67°R, room temperature is about 530°R, and water boils at 671.67°R. The relationship is simple: °R = °F + 459.67.

About Newton

Newton (°N) was devised by Isaac Newton around 1700 and published anonymously in 1701. The scale places water's freezing point at 0°N and boiling point at 33°N - a choice that allowed body temperature to fall at approximately 12°N. Newton used linseed oil as the thermometric fluid and described his scale in the Philosophical Transactions of the Royal Society. Although never widely adopted, it is historically significant as one of the earliest systematic temperature scales and directly inspired Ole Rømer, who visited Newton, and later Daniel Gabriel Fahrenheit, who built upon Rømer's work.
