About this calculator

The Greek alphabet has 24 letters running from alpha (α, Α) to omega (ω, Ω), each with an upper-case and lower-case form and a standard English transliteration of its name. Looking a letter up by its position — 1st is alpha, 12th is mu, 24th is omega — is a quick way to confirm a symbol's name or spelling without hunting through a full alphabet chart.

Mathematicians, physicists, engineers, and statisticians rely on these letters constantly as variable and constant names (α for angles, μ for mean, σ for standard deviation, Δ for change, π for the circle constant), and students frequently need to double-check a letter's name and case while reading a formula or writing one out — the same alphabet also names the letters used in Greek fraternity and sorority organization names.
