Math and science
The lower-case letter γ is used as a symbol for:
- gamma radiation in nuclear physics
- surface energy in materials science
- the Lorentz factor in theory of relativity
- The heat capacity ratio Cp/Cv in thermodynamics
- The activity coefficient in thermodynamics

The upper-case letter Γ is used as a symbol for:
- In mathematics, the gamma function (usually written as Γ-function) is an extension of the factorial to complex numbers
- In probability theory and statistics, the gamma distribution is a two-parameter family of continuous probability distributions.
- circulation in fluid mechanics
- As reflection coefficient in physics and electrical engineering
