It is designed for professionals, students, and anyone who needs a quick and accurate result. Conversion of Rankine (°R) to Celsius (°C) is crucial in Thermodynamics related measurements. You can avoid the risk of manual calculation errors and save valuable time using our Rankine (°R) to Celsius (°C) converter.

      Relation Between Rankine (°R) and Celsius (°C)

      Let me explain to you about the relation between Rankine °R and Celsius (°C) first before moving to the conversion process. Because it’s essential to grasp what these units represent.

      What is Rankine (°R)?

      Rankine is an absolute temperature scale, where zero degrees Rankine is absolute zero. Rankine (°R) is a unit of temperature measurement which is commonly used in Thermodynamics. The Rankine scale is used in some engineering and thermodynamic calculations, particularly in the United States..

      What is Celsius (°C)?

      Rankine (°R) is another unit of temperature measurement that is used in Weather forecasting. Celsius is a temperature scale where 0 degrees Celsius is the freezing point of water and 100 degrees Celsius is the boiling point of water at standard atmospheric pressure. 1. The Rankine scale is used in some engineering and thermodynamic calculations, particularly in the United States..

      How to Convert Celsius (°C)?

      The conversion between Rankine (°R) and Celsius (°C) follows a simple formula:

      Celsius (°C) = (rankine - 491.67) * 5 / 9 (°C)

      Rankine (°R) = (celsius + 273.15)*9/5 (°R)

      Where, (rankine - 491.67) * 5 / 9 and (celsius + 273.15)*9/5 is the value that allows you to convert between Rankine (°R) and Celsius (°C).

      So,

      1 Celsius = 493.46999999999997 (°R)

      And, 1 Rankine = -272.59444444444443 (°C)

      Examples of Converting Rankine (°R) to Celsius (°C)

      To convert any value from Rankine (°R) to Celsius (°C), simply multiply the amount of Rankine (°R) by the conversion factor:

      1 Celsius (°C) = 493.46999999999997 Rankine (°R)

      For example, if you want to convert 5 Rankine into Celsius and the conversion formula is ((rankine - 491.67) * 5 / 9), then:

      5 Rankine (°R) = -270.3722222222222 Celsius (°C)
