stærðakerfi
Stærðakerfi refers to the Icelandic system of measurement. Historically, Iceland utilized a variety of local units, but the country officially adopted the metric system in 1907. This transition aimed to standardize measurements and align with international practices, facilitating trade and scientific collaboration. The metric system, based on powers of ten, is now the mandatory system for all official purposes in Iceland, including commerce, industry, and education. Units like meters, kilograms, and liters are in everyday use. While the metric system is prevalent, some older, informal references to pre-metric units might occasionally be encountered in historical contexts or very specific traditional settings, though they hold no official standing. The adoption of the metric system has been a key factor in Iceland's integration into the global economy and scientific community.
