القيم المجدولة من −100 °C إلى 100 °C تم حسابها بالصيغ التالية، T بالكلفن وضغط البخار،Pw وPi بالباسكال
فوق سيولة الماء (Over liquid water)
For temperature range: 173.15 K to 373.15 K or equivalently −100 °C to 100 °C
فوق التجمد (Over ice)
For temperature range: 173.15 K to 273.15 K or equivalently −100 °C to 0 °C
في النقطة الثلاثية (At triple point)
ضغط البخار المشبع عند النقطة الماء الثلاثية واحد من أهم القيم الأساسية، كميات القيم المقبولة عالمياً على حسب مقاييس Guildner, Johnson and Jones (1976)هي :
