Surface tension is an important factor in the phenomenon of capillarity. Surface tension has the dimension of force per unit length, or of energy per unit area. [4] The two are equivalent, but when referring to energy per unit of area, it is common to use the term surface energy, which is a more general term in the sense that it applies also to ...
Similarly, surface tension can be denoted by either σ, γ or T. The table usually lists only one name and symbol that is most commonly used. The table usually lists only one name and symbol that is most commonly used.
The dyne per centimetre is a unit traditionally used to measure surface tension. For example, the surface tension of distilled water is 71.99 dyn/cm at 25 °C (77 °F). [4] (In SI units this is 71.99 × 10 −3 N/m or 71.99 mN/m.)
In electrostatics, σ represents surface charge density. In continuum mechanics, σ is used to signify normal stress. [16] In condensed matter physics, Σ denotes self-energy. The symbol can be used to signify surface tension (alternatively, γ or T are also used instead). In quantum mechanics, σ is used to indicate Pauli matrices.
differential vector element of surface area A, with infinitesimally small magnitude and direction normal to surface S: square meter (m 2) differential element of volume V enclosed by surface S: cubic meter (m 3) electric field: newton per coulomb (N⋅C −1), or equivalently, volt per meter (V⋅m −1)

Water potential is the potential energy of water per unit volume relative to pure water in reference conditions. Water potential quantifies the tendency of water to move from one area to another due to osmosis, gravity, mechanical pressure and matrix effects such as capillary action (which is caused by surface tension).
