stýrð

Stærð is Icelandic noun that denotes size, extent, magnitude or quantity. It is used both in everyday language and in technical contexts to describe how large something is or how much there is of something. The term can refer to physical dimensions, but also to abstract or measurable magnitudes.

In mathematics and the natural sciences, stærð designates a measurable quantity. Examples include length (measured in meters), area (square meters), volume (cubic meters), mass (kilograms), time (seconds) and temperature (Kelvin or Celsius). A given quantity may be a scalar stærð, which has only magnitude, or a vector stærð, which has both magnitude and direction. The concept of stærð is fundamental for measurement, comparison and calculation.

In computing and information technology, stærð is also used to describe data size, such as skrárstærð or gagnastærð. Data size is typically expressed in bytes, kilobytes, megabytes, gigabytes and beyond, and it is key to assessing memory usage, file size and bandwidth requirements.

In summary, stærð covers the broad idea of how large or how much something is, whether in the physical world, in mathematics, or in information technology. It is a flexible term that adapts to both concrete measurements and abstract quantities.
