Rankineasteikko

Rankineasteikko is a temperature scale where absolute zero is defined as 0 degrees R. This scale is named after the Scottish engineer William Rankine. It is an absolute temperature scale, meaning that 0 degrees R represents the lowest possible temperature. The Rankine scale is primarily used in the United States in some engineering and scientific applications, particularly in fields related to thermodynamics and heat transfer. It is directly proportional to the Kelvin scale, with a temperature in Kelvin multiplied by 1.8 equaling the equivalent temperature in degrees Rankine. Similarly, a temperature in degrees Rankine divided by 1.8 yields the equivalent temperature in Kelvin. The freezing point of water at standard atmospheric pressure is 491.67 degrees R, and the boiling point of water is 671.67 degrees R. This scale is useful because it avoids negative temperature values and provides a clear, linear relationship with energy.
