Greek Alphabet

📖 Introduction

Greek letters are the most common source of symbols in mathematics, physics, engineering and statistics: alpha for angles and significance levels, beta for regression coefficients, gamma for gamma rays, delta for increments, lambda for wavelength and eigenvalues, pi for the circle constant, sigma for standard deviation and omega for angular velocity. To read a formula you first have to recognise the letters and know what they usually stand for. This tool lists all twenty four Greek letters, giving for each the upper case form, the lower case form, the English name, a Chinese transliteration, the Latin equivalent, and one or two of its most common uses in mathematics and physics. In the grid the two cases sit side by side with the English name underneath, so shape and name are matched at a glance. Click any cell to open the full profile of that letter. Typing either alpha or the Chinese transliteration takes you straight to the right entry. All data is bundled locally and ready to use. Recognising the letters is only half the task; knowing what each one conventionally stands for is what makes a formula readable, so every entry carries one or two typical uses drawn from mathematics and physics. Upper and lower case are shown together because several Greek letters have a lower case form that looks nothing like the capital, such as sigma and final sigma, and because the two cases often mean different things in the same equation. The Latin equivalent is included for anyone typing the symbol in plain text or reading code that spells it out. Searching accepts either the English name or the Chinese transliteration, so the table works whichever language the reader thinks in. Two letters have variant forms that appear in technical writing, and the table notes the standard shape used in printed mathematics so that handwritten versions can be matched to it. Entries are ordered from alpha to omega, matching the conventional sequence used in dictionaries and reference sheets.

⚠️ Notes

• Meaning of use. Only the one or two most common meanings are listed; the same letter can mean different things in different subjects.
• Font dependence. Greek letters rely on the system font and may render incorrectly if it is missing.
• Pronunciation. The Chinese transliteration is only an approximation, not standard Greek pronunciation.
• Case shapes. Some upper case Greek letters look identical to Latin letters and must be told apart from context.
• Offline use. All data is bundled into the plugin and needs no network connection.
