  # Scalar vs. Scaler: What's the Difference? ## Scalar and Scaler Definitions

#### Scalar

A quantity, such as mass, length, or speed, that is completely specified by its magnitude and has no direction.

#### Scaler

An electronic circuit that records the aggregate of a specific number of signals that occur too rapidly to be recorded individually.

#### Scalar

(Mathematics) A number, numerical quantity, or element in a field.

#### Scaler

An electronic circuit that aggregates many signals into one.

#### Scalar

A device that yields an output equal to the input multiplied by a constant, as in a linear amplifier.

#### Scaler

An electronic or computer system that adjusts the size of a signal or graphic to fit on a screen etc.

#### Scalar

Of or relating to a scalar.

One who scales.

#### Scalar

(mathematics) Having magnitude but not direction.

#### Scaler

A tool or device for scaling fish.

#### Scalar

(computer science) Consisting of a single value (e.g. integer or string) rather than multiple values (e.g. array).

#### Scaler

One who, or that which, scales; specifically, a dentist's instrument for removing tartar from the teeth.

#### Scalar

Of, or relating to scale.

#### Scaler

An electronic pulse counter used to count pulses that occur too rapidly to be recorded individually

#### Scalar

(music) Of or pertaining to a musical scale.

#### Scalar

(physics) Relating to particles with a spin quantum angular momentum of 0 (known as spin 0).

#### Scalar

(linguistics) Pertaining to the dimension on which something is measured.

#### Scalar

(mathematics) A quantity that has magnitude but not direction; compare vector.

#### Scalar

(electronics) An amplifier whose output is a constant multiple of its input.

#### Scalar

In the quaternion analysis, a quantity that has magnitude, but not direction; - distinguished from a vector, which has both magnitude and direction.

#### Scalar

A variable quantity that cannot be resolved into components

#### Scalar

Of or relating to a directionless magnitude;
