Modulus is the diminutive from the Latin word modus meaning measure or manner. It, or its plural moduli, may refer to the following:

Physics and engineering

Moduli (physics), scalar fields for which the potential energy function has continuous families of global minima
The measurement of standard pitch in the teeth of a rotating gear
Bulk modulus, a measure of compression resistance
Elastic modulus, a measure of stiffness
Shear modulus, a measure of elastic stiffness
Young's modulus, a specific elastic modulus
Casting modulus used in Chvorinov's rule.

Modulus (digital counter), the number of states in a counter's count sequence
Modulo operation (a % b, mod(a, b), etc.), in both math and programming languages; results in remainder of a division

Modulus, the absolute value of a real or complex number ( $| c |$ )
Modulus (modular arithmetic), base of modular arithmetic
Similarly, the modulus of a Dirichlet character
Moduli space, in mathematics a geometric space whose points represent algebro-geometric objects
Conformal modulus, a measure of the size of a curve family
Modulus of continuity, a function gauging the uniform continuity of a function
Similarly, modulus of convergence
Modulus (algebraic number theory), a formal product of places of a number field
The modular function in the theory of Haar measure, often called simply the modulus
