What is Debye?
The Debye (symbol: D) is a unit of electric dipole moment, named after physicist Peter Debye. It is used to express the magnitude of molecular dipole moments. One Debye equals 3.336 × 10⁻³⁰ coulomb-metres (C·m). The Debye unit is commonly used because SI units give very small values for molecular dipole moments. Water has a dipole moment of 1.85 D.
