Omega symbol

Omega symbol

The Omega symbol and symbology have several meanings usually related to the end of something. It may be a project, a life, but the most common is that its meaning has to do with spirituality.

In spirituality, the symbolism of the omega is related to spiritual evolution and enlightenment, being the end of the cycle and the beginning of a new cycle. The symbol brings the human experience closer to the divine, because, according to traditions, from the spiritualities of the divine we leave and return to it.

It is also a symbol used in physics to represent the unit of measurement of electrical resistance.

In its variations, there are several other symbols, like the 8 of the Greek numerals, and the symbol of the infinite, all relationships with the concept of beginning and end of something. In the case of the infinite, it also represents a new beginning, because in order to start again something always needs an end.

Copy Paste omega symbol sign

If your keyboard does not have a omega symbol and the previous combination does not work, you can rely on the foolproof copy and paste

omega symbol on Keyboard

To enter the omega symbol from the keyboard, different combinations of keys are used depending on whether you want to indicate the upper case omega (Ω) or the lower case omega (ω).

For upper case omega:

Alt + 937

For lowercase omega the following combination should be used

Alt + 696

For those who do not know what it means, holding down the Alt key from the numeric keypad, press the keys successively after the + sign. When the Alt key is released, the chosen omega symbol will be obtained.

Since the key combinations are not universal and can depend on the keyboard, the font and the operating system, you can possibly fold over the old copy and paste:

ω | Ω

Omega symbol LaTeX

To insert the delta symbol in LaTeX you need to use the following syntax:

– \ omega for the tiny omega;

– \ Omega for upper case omega.


The word omega comes from the Greek “ó mega” which basically means something very long, very large, extensive, but which has a beginning, middle and end.


Omega ohm symbol

The concept of Alpha and Omega comes from the Judeo-Christian tradition. In the Bible, in the book of Revelation, in its first chapter and eighth verse, we have the following quote: “ I am Alpha and Omega, says the Lord, what is, what was, and is to come, the Whole Powerful ”.

The letter Alpha is the first letter of the Greek alphabet and the letter Omega is the last, so it is understood that God is the beginning and the end of everything. Everything starts in the divinity and ends in the divinity being that eternal.

The Bible was translated from Greek, so in this verse we speak of Alpha and Omega, but if it were a work in Portuguese, the equivalent would be to say “I am A and Z”.

The concept is that God has always been and always will be. God created everything that exists and determines when everything starts or ends.

Another biblical reference to such a concept is in the book of Genesis, in chapter 3, verse 19, in the expression “ For you are dust, and to dust you will return ”. It is noted that again the reference is made to the beginning and the end of something, in this case, of the man that God created out of the dust of the earth and when man dies he will return to being dust of the earth, because his body will decompose.

In addition to the Judeo-Christian tradition, in the spiritualist traditions, there is also the concept that human consciousness is a divine spark that separated from the Supreme Being to experience human life, to evolve, and to integrate with the divine again, this time integrating with it, in universal cosmic consciousness.

The lowercase letter ω is used as a symbol:

  • In physics, angular velocity or angular frequency.
  • In mathematics, the first transfinite ordinal number.
  • In Telecommunications, it is related to the spectrum of a continuous signal.
  • In electricity, pulsation of a signal.
  • In biochemistry, it indicates the number of carbons from the end of the aliphatic chain of a fatty acid. In unsaturated fatty acids, it indicates how many carbons are between the end of the chain and the double bond. Omega-3 fatty acids, for example, have three carbons double bond from the end of the chain.
  • In database theory, the null or unknown value

The symbol Ω (capital letter)

  • In mathematics, it represents the Space of differential forms.
  • In statistics, it represents the Sample space.
  • In computer science, it represents the set of all complex functions that are the lower bound of another given function.
  • In Telecommunications, it is related to the spectrum of a discrete signal.
  • In physics, Ω represents the ohm, a unit of electrical resistance.
  • It is the logo of the Omega watch firm.
  • The letter omega is the twenty-fourth and last letter found in the Greek alphabet and has symbols for both upper and lower case, these are Ω and ω respectively. On the other hand, in ancient Greece, it is written as Ωμέγα. Being that alpha and omega represent the beginning and the end in many historical and cultural aspects

omega Last letter of the Greek alphabet ( ωΩ ) with the value corresponding to the Latin ō. It is often symbolically taken to mean the end, the fulfillment, the death, above all in contrast to alpha, the principle.

chemistry O.-3 and O.-6 Category of fatty acids ( ➔ fats ) with 18, 20 or 22 carbon atoms. They are found in different varieties of fish and in vegetable oils.

Omega symbol PHYSICS

The letter ω is mainly used as a symbol of the angular velocity and the pulsation of a periodic phenomenon; in capital form, Ω, it is a symbol of the ohm. In physics of elementary particles, with the symbol Ω  indicates a particle ( or less ).


In the construction technique, in particular in the proportioning of tip loaded solids, omega indicates a load increase coefficient, variable with the slenderness, of the solid itself. The proportioning is thus carried out as if the solid were subjected to simple compression.

Uses of the omega symbol

Here are the main uses of the omega symbol in Mathematics and Physics:

– in the calculation of probabilities with the omega uppercase symbol (Ω) we indicate the sample space, which is the set of possible results of an event.

– The upper case omega is also used in physics as an ohm symbol.

– In kinematics , the lowercase omega symbol indicates angular velocity .

Furthermore, the omega symbol, unlike the alpha symbol, is used to indicate the end of the whole.


Omega in the alphabet is the name of the last letter of the Greek alphabet, the 24th letter. The letter of the Portuguese alphabet corresponding to the omega is “z”. Therefore, every concept of end is related to Omega.


An Omega tattoo usually has a religious bias and is always accompanied by the letter Alpha, both from the Greek alphabet. This tattoo is usually related to the concept of the divine. Opportunities that are not used with a religious concept are used as a symbol of the end of a cycle in the life of the person who tattooed it.
