Convert Rankine to Celsius
Rankine
The Rankine (°R) is an absolute temperature scale used primarily in thermodynamics. Like the Kelvin scale, it starts at absolute zero, the lowest possible temperature. The Rankine scale has the same increments as the Fahrenheit scale, so a temperature change of 1°R is equivalent to a change of 1°F. Absolute zero on the Rankine scale is 0°R, which corresponds to -459.67°F.
The Rankine scale was developed by the Scottish engineer and physicist William John Macquorn Rankine in the 19th century, specifically in 1859. Rankine created this scale to provide an absolute temperature scale using Fahrenheit's temperature divisions, making it particularly useful for thermodynamic calculations in engineering and physics. The Rankine scale is still used in some fields, particularly in the United States for thermodynamic calculations in engineering applications, though the Kelvin scale is more widely used internationally in scientific contexts.
Celsius
The Celsius (°C), also known as Centigrade, is a unit of temperature in the metric system. It is based on the freezing and boiling points of water, with 0°C defined as the freezing point of water and 100°C as the boiling point at standard atmospheric pressure. The Celsius scale is used widely in most countries for everyday temperature measurements.
The Celsius scale was developed by the Swedish astronomer Anders Celsius in 1742. Initially, Celsius defined 0° as the boiling point of water and 100° as the freezing point, but his scale was later inverted by other scientists, including Carolus Linnaeus. The modern Celsius scale, with 0°C as the freezing point and 100°C as the boiling point of water, became standard. The scale is part of the International System of Units (SI), and it is widely used in science, industry, and everyday life.
