Greek Alphabet Symbols & their Uses

Greek Alphabet Symbols & their Uses

There are 24 letters in the Greek alphabet. The letters in the Greek alphabet also have different symbols used to denote them. The Greek alphabet is widely used to demote various constants and values within the scientific and technology field. Greek letters are commonly used as numerical prefixes and to represent physical and mathematical quantities.

These Greek letters are used for everything from the values of resistance and resistivity, Permeability, thermal conductivity and much more. Here we are providing a table of the different Greek letters, symbols and what they are commonly used.

Greek Letter Name Upper Case Symbol Lower Case Symbol English Equivalent  Used to Denote
Alpha Α α a Angles, coefficients, attenuation constant, absorption factor, area
Beta Β β b Angles, coefficients, phase constant
Gamma Γ γ g Complex propagation constant (cap), specific gravity, angles, electrical conductivity, propagation constant
Delta Δ δ d Increment or decrement, determinant (cap), permittivity (cap), density, angles
Epsilon Ε ε e Dielectric constant, permittivity, electric intensity
Zeta Ζ ζ z Coordinates, coefficients
