Transpiration rate (E) is defined by the formula E = 1.6 gCO2 (VPa - VPi), where 1.6 is the ratio of the diffusivity of water to carbon dioxide, gCO2 is the conductance to carbon dioxide, VPa is the water vapor pressure of the air outside the leaf, and VPi is the water vapor pressure inside the leaf.
