At a glance:Compute Temperature C, Relative Humidity Pct, Vpd, Saturation Vapor Pressure, Actual Vapor Pressure from Temperature C, Relative Humidity Pct, Vpd, Saturation Vapor Pressure. Free online Hong Kong ecology calculator.

Formula

SVP = 0.6108 \times e^{\frac{17.27T}{T + 237.3}}

AVP = SVP \times \dfrac{RH}{100}

VPD = SVP \times \left(1 - \dfrac{RH}{100}\right)

$$SVP = 0.6108 \times e^{\frac{17.27T}{T + 237.3}}$$
$$AVP = SVP \times \dfrac{RH}{100}$$
$$VPD = SVP \times \left(1 - \dfrac{RH}{100}\right)$$

How to Use

  1. Enter Temperature C.
  2. Enter Relative Humidity Pct.
  3. Enter Vpd.
  4. Enter Saturation Vapor Pressure.
  5. The calculator returns Temperature C, Relative Humidity Pct, Vpd, Saturation Vapor Pressure, Actual Vapor Pressure.
