Obsolete Finnish units of measurement

Obsolete Finnish units of measurement is a science topic covered in the lgStudy science library.

Key takeaways

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

Reference excerpt

The obsolete Finnish units of measurement consist mostly of a variety of units traditionally used in Finland that are similar to those that were traditionally used in other countries and are still used in the United Kingdom (imperial units) and the United States (United States customary units).

History Very few of these units are sometimes still used in everyday speech and even when buying and measuring things as shorthand for similar amounts in the metric system. For example, kappa (sometimes called isokappa) is still used at markets to measure exactly five liters of potatoes. When ordering firewood, some customers (and even dealers) use syli to refer to a cubic meter, but some old people use the term to refer to various much larger amounts of firewood. Most Finnish obsolete units of measurement were identical to Swedish units of measurement, including units of length being based on the Swedish "foot" (29.69 cm) that was defined in 1605, since Finland was part of Sweden from the Middle Ages to 1809, but later some Russian units were also used in parallel throughout the 19th century. The measurements were first standardized by law in 1665 and were revised in 1734. Before this, measurements often varied between towns. The king's bailiff in the town of Porvoo, for example, used two sets of measures: a big one for collecting tax in kind from the populace and a smaller set to remit the assets to the king, keeping the difference for himself. However, nowadays the proverb mitata Porvoon mitalla (to measure in Porvoo units) has a positive meaning of measuring in excess or generously. Certain units were standardized to the metric system in 1861, and Finland fully converted to the metric system in 1886. The metric system was legally optional from 1887 and compulsory from 1892.

Length

Maritime units meripeninkulma – 1,852 m. Same as nautical mile. One angular minute at equator. kaapelinmitta – 185.2 m. 1⁄10 of a nautical mile. syli – 1.852 m. 1⁄1,000 of a nautical mile. Used for measuring depth. solmu – nautical miles per hour. Same as knot. Speed unit. Obsolete:

merisekunti* – 30.8666 m. 1⁄60 of nautical mile meritertia* – 0.51444 m. 1⁄3,600 of nautical mile

Liquid measure

Mass

Miscellaneous askel (pace) – Roughly one meter for an adult male—a rough but convenient way to measure distances while walking. hehto – hectoliter, 100 liters, potatoes kivenheitto (Throw of a rock) – 100 kyynärä (approx 60 m), today used to describe something to be very near (from Swedish stenkast also literally meaning "throw of a stone/rock") poronkusema – (approximately 7.5 km). A Sami measurement of distance; the distance a reindeer can travel before needing to stop to urinate. Today used to describe something that is at a very obscure distance away. Poronkusemaa kuukaudessa – (poronkusemas per month) similar to furlongs per fortnight, about 2.9 mm/s tusina – 12 (from Swedish "dussin" = dozen) toltti – 12 (lumber) tiu – 20 (eggs) (from Swedish tjog, previously used for 20 of anything, not only eggs) puntti – 20 (matchboxes) kerpo – 31 (lampreys; 30 as a bunch and one for tying) krossi – 144 (items) (from Swedish gross = 12 dozens; originally from French douzaine grosse meaning "large dozen") kiihtelys – 40 (squirrel pelts) riisi – 500 (paper sheets) (from Swedish ris, with the same meaning) tonni – 1,000 (usually refers to 1,000 kg, but can refer also anything of 1,000, especially money) motti – 1 m3 (firewood or waste paper), also 1 dm3 in "motin pullo", a 1-litre bottle, usually of alcohol

Worked examples

Example 1 — a first encounter with Obsolete Finnish units of measurement

Start with the simplest possible case. Write down what Obsolete Finnish units of measurement 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 Obsolete Finnish units of measurement 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 Obsolete Finnish units of measurement 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 Obsolete Finnish units of measurement

In research
Obsolete Finnish units of measurement 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 Obsolete Finnish units of measurement 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
Obsolete Finnish units of measurement is common in secondary-school and first-year university syllabi. It links to neighbouring topics Obsolete units of measurement, Science and technology in Finland, Systems of units, so understanding it makes those chapters shorter.
In everyday life
Look for Obsolete Finnish units of measurement 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.
