Greek Alphabet Symbols & Characters: mathematical uses

The Greek alphabet is widely used in mathematical and scientific equations with letters like psi, rho, eta, mu, omega and many more being widely used.


Letter & Symbols Includes:
Greek alphabet     Mathematical symbols     Mathematical constants     Typographical symbols    


The Greek alphabet is widely used to demote various constants and values within the scientific and technology arenas. Letters including omega, eta, rho, mu and many more are used to denote a whole range of mathematical, scientific and engineering measures. Everything from resistivity, through to impedance, permeance and ratios of circles and much more.

The Greek alphabet only has 24 letters compared to the Latin based script that uses 26. However the Greek alphabet does have both capital and small versions, and virtually all of the letters are widely used for a variety of different measures.

The different Greek letters have different meanings or they are used to denote different measures as outlined in the list below.
