For the English units tab, it appears that the submitter obtained his equations (as a function of temperature) from Perry's Chemical Engineering Handbook. However, the units in Perry's are in cal/gmol-K. While the submitter did correctly convert deg F to deg K, he did not convert the units from calories to BTU or from gmol to lbmol. Therefore, for the English units table, the user must muliple the answer by 453.6/1055 to convert cal/gmol to BTU/lbmol.
Correction to previous review. "To convert from cal/gmol to BTU/lbmol, multiply by 4.184 (J/cal) *453.6(gmol/lbmol)/1055 (BTU/J)".

The error in the workbook was that the metric numbers were presented as "KJ/mole K" where is should have stated "J/mol K". Check some of the values in the spreadsheet with this table as a sampling:
