How to Convert Celsius to Rankine
To Fahrenheit: °F = °C × 9/5 + 32. To Kelvin: K = °C + 273.15. To Rankine: °R = (°C + 273.15) × 9/5.
°C = K − 273.15. The Celsius and Kelvin scales have identical degree sizes — they differ only by an offset of 273.15.
For example, 1 Celsius (°C) = 493.47 Rankine (°R).

About Celsius (°C)
Definition
The degree Celsius is a unit of temperature on the Celsius scale, where 0 °C is the freezing point and 100 °C is the boiling point of water at standard atmospheric pressure.
Mathematical Relationship
°C = K − 273.15. The Celsius and Kelvin scales have identical degree sizes — they differ only by an offset of 273.15.
Conversion Formula
To Fahrenheit: °F = °C × 9/5 + 32. To Kelvin: K = °C + 273.15. To Rankine: °R = (°C + 273.15) × 9/5.
Practical Applications
Weather reports, cooking temperatures, body temperature (37 °C normal), refrigerator settings (2–4 °C), and industrial processes.
Interesting Facts
−40 °C = −40 °F — the only point where Celsius and Fahrenheit scales intersect. The hottest recorded temperature on Earth was 56.7 °C in Death Valley.
Common Mistakes
Forgetting the °C × 9/5 + 32 offset when converting to Fahrenheit. Also, assuming 0 °C = 0 K (actually 0 °C = 273.15 K).
Educational Tips
Key anchors: 0 °C = water freezes, 37 °C = body temp, 100 °C = water boils. For quick °C→°F: double and add 30 (approximate).
About Rankine (°R)
Definition
The degree Rankine is an absolute temperature scale using the Fahrenheit degree size, where 0 °R equals absolute zero (−459.67 °F).
Mathematical Relationship
°R = °F + 459.67. The Rankine scale is to Fahrenheit what Kelvin is to Celsius. Same degree size as Fahrenheit.
Conversion Formula
To Fahrenheit: °F = °R − 459.67. To Celsius: °C = (°R − 491.67) × 5/9. To Kelvin: K = °R × 5/9.
Practical Applications
US engineering thermodynamics calculations, gas turbine design, and some aerospace engineering applications.
Interesting Facts
Water freezes at 491.67 °R and boils at 671.67 °R. The Rankine scale is one of the four main temperature scales still in use.
Common Mistakes
Confusing Rankine with Réaumur — both use 'R' but are completely different scales. Use °R vs. °Ré to distinguish.
Educational Tips
Rankine is to Fahrenheit as Kelvin is to Celsius. Both absolute scales start at 0 = absolute zero, just with different degree sizes.
