Key Differences
Omega is the last letter of the Greek alphabet, signifying completion or the end. In contrast, Ohm is a unit of electrical resistance named after the German physicist Georg Simon Ohm.
In various cultural and religious contexts, Omega is used metaphorically to denote the end or finality. On the other hand, Ohm is used scientifically to measure how difficult it is for electricity to flow through a conductor.
Omega often appears in a stylized form as a symbol in fraternal organizations and logos, highlighting its deep cultural resonance. Whereas Ohm is symbolized by an uppercase Greek letter omega (Ω), emphasizing its scientific and technical significance.
In literature and popular culture, "Alpha and Omega" represents the beginning and the end, illustrating Omega's symbolic versatility. Conversely, the Ohm symbol is ubiquitous in electronics and physics textbooks, denoting a specific measurable property.
Omega has also been adopted in various branding and design contexts to convey completeness and quality, such as in the name of the famous watch brand Omega. Meanwhile, Ohm remains a fundamental concept in physics and engineering education, essential for understanding electrical circuits.

Ohm
The SI unit of electrical resistance, equal to the resistance of a conductor through which a current of one ampere flows given a one-volt potential across the conductor. See Table at measurement.
Omega
The last of a series; the end.
Ohm
The ohm (symbol: Ω) is the SI derived unit of electrical resistance, named after German physicist Georg Ohm. Various empirically derived standard units for electrical resistance were developed in connection with early telegraphy practice, and the British Association for the Advancement of Science proposed a unit derived from existing units of mass, length and time, and of a convenient scale for practical work as early as 1861.
Omega
In cosmology theory, the ratio of the average density of matter in the universe to its critical density.
Ohm
The SI unit of electrical resistance, transmitting a current of one ampere when subjected to a potential difference of one volt.
Omega
See omega baryon.
Ohm
In the International System of Units, the derived unit of electrical resistance; the electrical resistance of a device across which a potential difference of one volt causes a current of one ampere. Symbol: Ω
Omega
See omega meson.
Ohm
The standard unit in the measure of electrical resistance, being the resistance of a circuit in which a potential difference of one volt produces a current of one ampére. As defined by the International Electrical Congress in 1893, and by United States Statute, it is a resistance substantially equal to 109 units of resistance of the C. G. S. system of electro-magnetic units, and is represented by the resistance offered to an unvarying electric current by a column of mercury at the temperature of melting ice 14.4521 grams in mass, of a constant cross-sectional area, and of the length of 106.3 centimeters. As thus defined it is called the international ohm.
