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.
