03 FAQ

How do I type Greek letters like π or Σ?

Easiest is to copy them from the keys below. In Word, type the code and press Alt+X, 03C0 for π, 03A3 for Σ. On Mac, the Character Viewer lists the full Greek block. A Greek keyboard layout maps them to Latin keys.

What is the difference between μ (mu) and the micro sign µ?

They look identical but are different characters: µ (U+00B5, micro sign, Alt+0181) is meant for units like µm, while μ (U+03BC, Greek small mu) is the letter. Many systems treat them alike, but use the micro sign for measurements.

Why does Ω mean ohms?

Ω is capital Greek Omega, adopted as the symbol for electrical resistance in ohms. The dedicated Ohm Sign (U+2126) looks the same but Greek Omega (U+03A9) is what most keyboards and fonts use.
