mælieiningakerfi
Mælieiningakerfi, literally “measurement units system” in Icelandic, refers to the set of standardized units used for measuring length, mass, time, temperature, and other physical quantities in Iceland. It is largely aligned with the International System of Units (SI), the same system employed by most countries worldwide. The basic SI units that are routinely used in Iceland include the meter for length, kilogram for mass, second for time, kelvin for temperature, ampere for electric current, mole for the amount of substance, and candela for luminous intensity. Derived units such as kilogram‑meter per second squared for force or pascal for pressure are also common in scientific literature and engineering practice.
The Icelandic mælieiningakerfi was formally adopted in the early 20th century, following the adoption of the
While the legal framework obliges the use of the metric system, Iceland inherits a dual system attitude:
