Units of Measurement Name Generator
Generate names for fictional, archaic, and fantastical units of measurement covering mass, volume, length, and time. The generator draws from four categories: solid or mass units like 'Anvils', 'Boulders', and 'Skulls'; liquid or volume units like 'Cauldrons', 'Hogsheads', and 'Thimbles'; length units like 'Arrow-Flights', 'Wingspans', and 'Stonethrows'; and time units like 'Heartbeats', 'Moonrises', and 'Tides'. Perfect for fantasy and science fiction worldbuilding, historical fiction, tabletop RPGs, game design, and any creative project that needs authentic-sounding invented or pre-modern units of measure.

About the Units of Measurement Name Generator

The Units of Measurement Name Generator creates names for fictional, archaic, and fantastical units of measurement covering four categories: mass and solid measurement (Anvils, Boulders, Skulls), liquid and volume measurement (Cauldrons, Hogsheads, Thimbles), length and distance measurement (Arrow-Flights, Wingspans, Stonethrows), and time measurement (Heartbeats, Moonrises, Tides).

Every generated unit name is a concrete noun that functions as a measurement — physical objects, natural phenomena, or body parts used as measurement standards. This mirrors how real historical units of measurement actually worked: the foot was literally the length of a foot, the acre was the area a yoke of oxen could plough in a day, and the rod was a standard measuring staff used in surveying.

For any world that predates standardised measurement — or that never developed it — a believable set of unit names makes the world feel genuinely lived-in, with a history of practical measurement born from the objects and phenomena available to people's daily experience.

Units of Measurement in History and Fiction

Historical Pre-Metric Measurement

Before the metric system, every culture developed its own units of measurement. The English system alone included the barleycorn (1/3 inch), the furlong (201 metres, from "furrow-long"), the hogshead (a barrel of 63 US gallons), the chain (20 metres, used in surveying), and the fortnight (14 nights). These units were derived from real objects and practices — they made practical sense to the people who used them, even if they seem arbitrary from a modern perspective.

Measurement Units in Fantasy Worlds

Fictional worlds benefit enormously from their own measurement vocabulary. Terry Pratchett's Discworld uses units like the "thaum" (a unit of magical energy). Brandon Sanderson's Stormlight Archive uses "heartbeats" as a precise time measurement, grounded in the world's physics. George R.R. Martin's Westeros uses "leagues" for distance, anchoring his world in medieval European convention. A distinctive set of measurement terms communicates, without explanation, that a world has its own history and practical knowledge tradition.

How to Use These Unit Names

  • Fantasy worldbuilding: Establish the measurement vocabulary of a pre-metric fantasy society — what units do merchants, builders, farmers, and navigators use?
  • Fiction writing: Give your characters naturally embedded ways of expressing quantity and time that feel native to their world.
  • Tabletop RPGs: Add flavour to your campaign by having NPCs use world-specific units — "about three Stonethrows from here" or "she weighs a good twelve Skulls".
  • Game design: Name the measurement units displayed in your game's UI or referenced in the lore — especially effective for survival and crafting systems.
  • Historical fiction: Use the archaic-feeling unit names to give pre-modern settings authentic non-metric measurement language.
  • Satire and humour: The inherent absurdity of units like "Chickens" or "Cannonballs" as mass measurements makes the generator a great source of comic worldbuilding.

What Makes a Good Measurement Unit Name?

Heartbeats

Body-based time units are some of the most evocative because they ground cosmic time in a deeply personal physical experience. "Three hundred heartbeats" conveys both precision and urgency in a way that "five minutes" cannot.

Stonethrows

Action-based distance units describe measurement in terms of physical capability — how far a person can throw, shoot an arrow, or walk in a day. These units have an immediately intuitive meaning even without a precise numerical equivalent.

Hogsheads

Container-based volume units feel authentically pre-industrial — measurement by what you have on hand, the vessels that merchants and brewers and alchemists actually used. They suggest a world of practical, embodied knowledge rather than abstract standardisation.

Frequently Asked Questions
Is the generator free to use? +
Yes — the Units of Measurement Name Generator is completely free with no registration required.
Can I use these unit names in a published game or novel? +
Yes — all generated unit names are free to use in personal or commercial projects, including tabletop RPG supplements, video games, novels, and worldbuilding documents. No attribution is required.
How do I decide which unit category fits my world? +
Think about what your characters actually need to measure in daily life. A maritime trading world needs strong volume and distance units. A farming society needs mass and time units. An arcane academic setting might formalise time units around celestial or magical cycles. Pick units that reflect the practical knowledge and resources of the culture using them.
Are these based on real historical units of measurement? +
The generator is inspired by how real pre-metric units worked — derived from physical objects, body parts, and natural phenomena that were available to people in daily life. Historical units like the foot (the length of a foot), the furlong (the length of a furrow), and the hogshead (a specific barrel size) all followed this same pattern of grounding abstract measurement in concrete, familiar things.
What types of units does the generator produce? +
The generator produces fictional units across four categories: mass and solid measurement (objects used to weigh things), liquid and volume measurement (containers and natural volumes), length and distance measurement (actions and body-based distances), and time measurement (natural phenomena and body rhythms). Each generated unit is a concrete noun that functions as a measurement standard.
Is there API access available? +
Yes. FunGenerators offers API access for developers. Visit the FunGenerators API page for details on integration and plans.
