Millilegr

Millilegr is a fictional monetary unit used in speculative fiction and worldbuilding to illustrate decimal-based currency systems in imagined economies. The name blends the SI prefix milli- with a fictional base unit, legr, yielding a unit equal to one thousandth of a legr. In many in-world systems, the legr serves as the primary unit of account, while millilegrs function as subunits for everyday transactions, similar to cents or pence in real-world currencies. Denominations commonly appear as 1, 5, 10, 25, and 50 millilegrs, with occasional larger submultiples such as 100 millilegrs, depending on the author’s design.

Use and role in narratives: Millilegrs are typically used for small purchases and microtransactions, while the legr or its multiples are used for larger prices. Some settings employ digital or holographic tokens for millilegrs to enable swift cross-border or cross-domain exchange and to illustrate modern fintech concepts.

Origins and reception: The concept first appeared in worldbuilding communities and science fiction writings in the late 20th and early 21st centuries. It has been used to explore topics such as currency decimalization, inflation, exchange rates, and the interaction between different regions within a fictional economy.

Limitation: The term is not standardized and has no official real-world status; it remains a construct of fiction and game design.
