From the reference table “Saturated vapor pressure at a temperature of 0-374 C” we choose for a temperature of 6 C Psat = 0.9353 kPa.
Under the condition, the partial pressure of water vapor = 620Pa, which is equal to 0.62kPa.
Accordingly, according to the formula Ф (relative air humidity) = Р (partial pressure) / Рsat (saturated vapor pressure), it means Ф = 0.62kPa / 0.9353kPa = 0.66 = 66%
