Water Boiling Point at Higher Pressures – Data & Calculator

Calculator and data table for determining the boiling point of water at various absolute pressures. The boiling point of water depends on pressure - when water is heated, it reaches a temperature at which the vapor pressure is large enough that bubbles form inside the water. Output temperature is given in °C, °F, K and °R. Pressure must be within ranges: 1-220 bara, 14.7-3200 psia, 760-165000 mm Hg, or 30-6500 in Hg.
