Hobbit (unit)

Hobbit (unit) is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Hobbit (unit) rather than just read about it. In short: The hobbit (also hobbett, hobbet, or hobed, from Welsh: hobaid) is a unit of volume or weight formerly used in Wales for trade in grain and other staples. It was equal to two and a half bushels, but was also often used as a unit of weight, which varied depending on the material being measured.

Key takeaways

  • Hobbit (unit) belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Hobbit (unit) to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Hobbit (unit) from memory before moving on to harder problems.

Reference excerpt

The hobbit (also hobbett, hobbet, or hobed, from Welsh: hobaid) is a unit of volume or weight formerly used in Wales for trade in grain and other staples. It was equal to two and a half bushels, but was also often used as a unit of weight, which varied depending on the material being measured. The hobbit remained in customary use in markets in northern Wales after Parliament standardized the Winchester bushel as the unit of measure for grain, after which courts gave inconsistent rulings as to its legal status.

Usage The hobbit was defined as a measure of volume, two and a half imperial bushels, but in practice it was often used as a unit of weight for specific goods. According to George Richard Everitt, Inspector of Corn Returns for Denbigh in northern Wales, when examined by the House of Commons in 1888, grains were sold by the hobbit, measured by weight. A hobbit of oats weighed 105 pounds (48 kg), a hobbit of barley 147 pounds (67 kg), and a hobbit of wheat 168 pounds (76 kg). The figures in hobbits were then converted to standard imperial bushels for official reporting. In addition to grains, there was also a hobbit of beans at 180 pounds (82 kg), and in Flintshire, a 200-pound (91 kg) hobbit of old potatoes, or 210 pounds (95 kg) of new potatoes. Around 1600, Welsh farmland was sometimes denominated by its productive capacity or measure of seedness instead of its physical area, so that in at least one case a plot was registered as "a hobbett of land", that is, large enough to grow one hobbit of grain per year. Already in 1863, the hobbit was used as an example of the "customary confusion in our British weights and measures". An anonymous contributor to Charles Dickens's journal All the Year Round, arguing in favour of the decimal metric system, noted that

If [I buy wheat] at Wrexham, [I must order] by the hobbet of one hundred and sixty eight [pounds] [76 kg]. But, even if I do happen to know what a hobbet of wheat means at Wrexham, that knowledge good for Flint is not good for Caernarvonshire. A hobbet of wheat at Pwlheli contains eighty-four pounds [38 kg] more than a hobbet at Wrexham; and a hobbet of oats is something altogether different; and a hobbet of barley is something altogether different again.

Legal issues There was some dispute about the legality of the hobbit as a non-standard measure in commerce after Parliament established the Winchester measure. The hobbit's mixed use as a unit of both volume and of weight complicated the issue, as laws applied to the two cases differently. Courts sometimes nullified grain contracts denominated in hobbits, and sometimes upheld them, according to varying customs in precisely how hobbits were defined and measured. In 1825, the Exchequer of Pleas heard the case of Tyson v. Thomas, regarding an unfulfilled 1823 contract for the delivery of 20 hobbits of barley in Llanrwst, at 10 shillings each. The price of barley subsequently increased, and the seller did not make delivery. The buyer sued, and the defendant argued that the contract was illegal because it was not based on the standard Winchester bushel. According to testimony, the Llanrwst market used a half-hobbit measure of two 21-imperial-quart (24 L) pecks, but in practice a hobbit could vary from 80 to 84 imperial quarts (91 to 95 L). The court agreed with the seller, finding that the hobbit was impermissible because it was not a fixed integer multiple of the bushel. The contract was therefore void. A similar argument was raised before the Exchequer of Pleas in Owens v. Denton, concerning a sale of malt, but the court held that the question of measures had no effect on the case because the account had already been settled. The 1852 case Hughes v. Humphreys concerned a contract for the sale of 100 hobbits of wheat at 18 shillings per hobbit. Following custom, the grain was actually delivered in sacks weighed out to 252 pounds (114 kg) each, and converted to 168-pound (76 kg) hobbits. The seller sued to obtain payment from the buyer, who argued that the contract was unenforceable because the hobbit was a non-standard and illegal measure of volume, contrary to Parliamentary establishment of the Winchester bushel for trade in grain. The magistrate at the local assizes in Flintshire, J. Williams, found for the defendant, voiding the contract. This ruling was reversed by the Court of Queen's Bench, which reasoned that, in distinction to the Tyson case, the hobbit in this instance was used as a measure of weight, not volume, and was defined as a fixed multiple of the pound. Because the sale of grain in pounds was allowed, the contract was deemed valid and was enforced.

Worked examples

Example 1 — a first encounter with Hobbit (unit)

Start with the simplest possible case. Write down what Hobbit (unit) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hobbit (unit) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hobbit (unit) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hobbit (unit)

In research
Hobbit (unit) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Hobbit (unit) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Hobbit (unit) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Obsolete Welsh units of measurement, Units of mass, Units of volume, so understanding it makes those chapters shorter.
In everyday life
Look for Hobbit (unit) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
