What is a Celsius and a Rankine?
Degree Celsius (°C) is a unit of temperature on the Celsius scale, a temperature scale named after the Swedish astronomer Anders Celsius. It is one of the most common temperature scales used worldwide, particularly in science and in most countries for everyday measurements. The scale defines 0°C as the freezing point of water and 100°C as the boiling point of water at standard atmospheric pressure.
The Rankine scale (°R or °Ra) is an absolute thermodynamic temperature scale named after the Scottish engineer and physicist William John Macquorn Rankine. Similar to the Kelvin scale, its zero point is absolute zero, but the degree size is the same as that of the Fahrenheit scale.
Note: The Celsius is part of the metric (SI) system, primarily used globally in science and trade. The Rankine belongs to the imperial/US customary system.
History of the Celsius and Rankine
The Celsius scale was developed by Anders Celsius in 1742. Originally, he proposed a scale where 0° represented the boiling point of water and 100° represented the freezing point. This scale was later inverted by Carl Linnaeus or Jean-Pierre Christin to the form we use today. The degree Celsius was adopted as part of the International System of Units (SI), where it is defined relative to the Kelvin scale (0°C = 273.15 K).
The scale was proposed by William Rankine in 1859, shortly after the Kelvin scale was developed. It was created to provide an absolute temperature scale that directly corresponded with the Fahrenheit degrees used widely in engineering at the time.
Common Uses for degrees Celsius and degrees Rankine
Explore the typical applications for both Celsius (metric) and Rankine (imperial/US) to understand their common contexts.
Common Uses for degrees Celsius
- Weather: Everyday weather reporting and forecasting in most parts of the world.
- Domestic: Domestic temperature settings (thermostats, ovens).
- Science: Scientific research, especially in chemistry and biology, alongside Kelvin.
- Medical: Medical temperature measurements.
- Culinary: Food storage and cooking temperatures.
Common Uses for degrees Rankine
- Engineering (Thermodynamics): Used in some engineering fields, particularly in the United States, where calculations often involve Fahrenheit. It simplifies thermodynamic calculations (like the ideal gas law) when using Imperial units.
- Historical Context: Found in older engineering texts and data.
Frequently Asked Questions
Questions About Celsius (°C)
Is Celsius the same as Centigrade?
Yes, 'Celsius' and 'Centigrade' refer to the same temperature scale. The name was officially changed to Celsius in 1948 to honor Anders Celsius and avoid confusion with 'centigrade' as an angular unit.
How does Celsius relate to Kelvin?
The Celsius scale is defined relative to the Kelvin scale, the SI base unit for temperature. A temperature difference of 1°C is equal to a difference of 1 K. To convert Celsius to Kelvin, add 273.15 (K = °C + 273.15).
Why is Celsius used so widely?
Its definition based on the freezing and boiling points of water at standard pressure makes it intuitive for everyday life and many scientific applications. It provides a convenient reference range for common environmental temperatures.
About Rankine (°R)
What is absolute zero on the Rankine scale?
Absolute zero is 0 °R, which is equivalent to -459.67 °F or -273.15 °C.
How does Rankine relate to Fahrenheit?
A change of 1 °R is equal to a change of 1 °F. The formula is °R = °F + 459.67.
How does Rankine relate to Kelvin?
The Rankine scale uses Fahrenheit degrees, while Kelvin uses Celsius degrees. Both start at absolute zero. The formula is °R = K × 9/5.
