Common Uses

α	alpha	-
β	beta	coefficient of volume expansion
γ	gamma	specific weight, shearing strain
δ	delta	the italicized δ may be used in front of a property (typically represented by a letter, usually a capital letter), in place of the letter d. In this case δ is used to designate inexact differentials (in contrast to d for exact differentials). This may be encountered frequently in thermodynamics
ε	epsilon	normal strain
ζ	zeta	-
η	eta	efficiency
θ	theta	-
ι	iota	-
κ	kappa	-
λ	lambda	-
μ	mu	viscosity coefficient
ν	nu	-
ξ	xi	-
ο	omicron	-
π	pi	ratio of cirumference over diameter
ρ	rho	density
σ	sigma	normal stress, Stefan Boltzmann constant
τ	tau	shear stress, torque
υ	upsilon	-
φ	phi	-
χ	chi	-
ψ	psi	stream function
ω	omega	-
Α	alpha	-
Β	beta	-
Γ	gamma	-
Δ	delta	change between two variables
Ε	epsilon	-
Ζ	zeta	-
Η	eta	-
Θ	theta	-
Ι	iota	-
Κ	kappa	-
Λ	lambda	-
Μ	mu	-
Ν	nu	-
Ξ	xi	-
Ο	omicron	-
Π	pi	-
Ρ	rho	-
Σ	sigma	-
Τ	tau	-
