NH₃ Vapor Pressure ⇆ Saturation Temperature

Enter either Temperature or Pressure. Choose pressure basis (Absolute or Gauge). Excel export includes live formulas.

Result Pressure–
Method (Antoine, NH₃)
  • Form: log10(P_bar_abs) = A − B/(T_K + C)
  • Ranges:
    • 164.0–239.6 K: A=3.18757, B=506.713, C=−80.78
    • 239.6–371.5 K: A=4.86886, B=1113.928, C=−10.409
  • Invert: T_K = B/(A − log10(P_bar_abs)) − C
  • Atmospheric pressure (gauge↔absolute): 1.01325 bar.
