Triple Point of Water to Rankine Converter

Convert a TPW ratio into Rankine. Here TPW means a temperature expressed relative to the triple point of water, with TPW = 1 equal to 273.16 K.

Formula: degR = TPW x 491.688. The reverse tool is Rankine to triple point of water.

This is a specialist temperature conversion. It is mainly useful when a normalized TPW value needs to be displayed on an absolute Fahrenheit-sized scale, such as Rankine.

One reference point does most of the work

TPW = 1 represents the triple point of water at 273.16 K. Rankine is tied to kelvin by a 9/5 scale factor, so TPW = 1 becomes 491.688 degR. Any other TPW value scales from that point without an offset.

If you need the more common absolute-temperature steps, use TPW to Kelvin, Kelvin to TPW, Rankine to Kelvin, or Kelvin to Rankine. The full temperature converter hub has the rest.
