Water Potential Calculator
Calculate solute potential and total water potential from ionization, concentration, temperature, and pressure potential.
Formula
Solute potential Psi_s = -iCRT; total Psi = Psi_s + Psi_p.
About the Water Potential Calculator
Calculate solute potential and total water potential from ionization, concentration, temperature, and pressure potential. This tool keeps the requested measurements separate and applies the named method instead of substituting an unrelated general estimate.
How the Water Potential Calculator Works
Temperature is converted to kelvin and the gas constant 0.008314 L MPa mol^-1 K^-1 keeps the result in megapascals.
Formula
Solute potential Psi_s = -iCRT; total Psi = Psi_s + Psi_p.
The calculation runs in your browser. Values are validated for required ranges, compatible units, and method-specific restrictions before results are displayed.

Accuracy and Limitations
The equation assumes dilute ideal behavior. Biological tissues may require measured osmotic coefficients and additional matric or gravitational terms.
Keep units consistent, use measurements that represent the actual situation, retain full precision during the calculation, and round only the final answer. Professional decisions may require current official rules, field measurements, laboratory methods, or specialist review.
