The symbol Ω was suggested, because of the similar sound of ohm and omega, by William Henry Preece in 1867. In documents printed before WWII the unit symbol often consisted of the raised lowercase omega (ω), such that 56 Ω was written as 56ω.

Omega Symbol in Greek Alphabet (Ohm Symbol)
In the Greek number system, it was taken as the symbol of 800. The letter is known as the Big O in contrast to omicron, which is known as the little O. Omega indicates the end/the last. The capital omega (Ω) is used to show ohm in physics.
What does this symbol mean Ω?
Greek Letter Omega
The 24th and last letter of the Greek alphabet, Omega (Ω), essentially means the end of something, the last, the ultimate limit of a set, or the “Great End.” Without getting into a lesson in Greek, Omega signifies a grand closure, like the conclusion of a large-scale event.
Is measured in ohms symbolized by the Greek letter omega?
Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.
What does Ω mean in engineering?
ohms
In electromagnetism and engineering, the uppercase Ω is used as the symbol for ohms, which are the units of electrical resistance. In physics and other sciences, the lowercase ω is often used to represent angular frequency.
Why are Greek letters used in physics?
Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities.
What does omicron mean in math?
Omicron is the 15th letter of the Greek alphabet. In the system of Greek numerals it has a value of 70. It is rarely used in mathematics because it is indistinguishable from the Latin letters O, o and easily confused with the digit 0. This letter is derived from the Phoenician letter ayin .

What does omega mean in math?
Ω (definition) Definition: A theoretical measure of the execution of an algorithm, usually the time or memory needed, given the problem size n, which is usually the number of items. Informally, saying some equation f(n) = Ω (g(n)) means it is more than some constant multiple of g(n).
Why are there so many Greek letters in math?
Because European mathematics is very heavily rooted in the mathematics of ancient Greece, and due to the need for many symbols to represent constants, variables, functions and other mathematical objects, mathematicians frequently use letters from the Greek alphabet in their work.
What is G in Greek?
Gamma. Γ γ G. Between Y as in yes and G as in go, but with no hard ‘G’ sound – more of a soft ‘H’ followed by the ‘Y’ sound in yes.

Is Greek a hard language to learn?
Greek is a relatively difficult language to master. It’s more difficult for an English speaker than Dutch, French, and German, but it might be easier than Russian and Arabic. The reason for the Greek language’s difficulty is that it’s less closely related to English than other languages.
