FAQ

What is the Water Potential?
Water Potential is the potential energy of water per unit volume relative to pure water in reference conditions. Water Potential is usually measured using the Pascal for Pressure. Note that the value of Water Potential is always positive.
Can the Water Potential be negative?
No, the Water Potential, measured in Pressure cannot be negative.
What unit is used to measure Water Potential?
Water Potential is usually measured using the Pascal[Pa] for Pressure. Kilopascal[Pa], Bar[Pa], Pound Per Square Inch[Pa] are the few other units in which Water Potential can be measured.
