German units of measurement refer to the traditional system of measurements used in Germany prior to the adoption of the metric system. Historically, Germany, like many other countries, used a variety of units for length, area, volume, and mass, which were not standardized and could vary from one region to another. Some of these units included: 1. **Length**: - **Zoll**: Inch (1 Zoll = 2.

Portugal uses the metric system as its standard system of measurement. This includes units such as: - **Length**: meter (m), centimeter (cm), kilometer (km) - **Mass**: gram (g), kilogram (kg) - **Volume**: liter (L), milliliter (mL) These metric units are used in everyday life, in commerce, and in scientific contexts.
The Apothecaries' system is a historical system of measurement that was traditionally used in pharmacy and medicine. It originated in the Middle Ages and became widely adopted in Europe and the Americas before the adoption of the metric system. This system mainly includes measurements for weight and volume, specifically designed for the preparation and dispensing of medications.
Carolingian pound by Wikipedia Bot 0
The Carolingian pound (Latin: *libra Carolingia*) was a unit of weight used during the Carolingian Empire, which was established by the Frankish king Charlemagne in the late 8th and early 9th centuries. This pound was part of a system of weights and measures that facilitated trade and economic organization within the empire. The Carolingian pound is historically significant as it reflects the administrative reforms made by Charlemagne to standardize measures across his diverse realm.
Carucate by Wikipedia Bot 0
A carucate is a historical measure of land area used in medieval England, primarily during the time of the Domesday Book in the 11th century. It is often associated with the concept of land suitable for farming and was a unit of assessment for taxation.

Bamboo (unit) by Wikipedia Bot 0
Bamboo is a unit of measurement that is often used in the context of environmental science and ecology to represent carbon sequestration or the amount of biomass produced by bamboo plants. Bamboo is known for its rapid growth and ability to absorb carbon dioxide from the atmosphere, making it a significant factor in discussions about sustainable forestry and carbon offsetting.
Byzantine units of measurement refer to the various systems of measurement used in the Byzantine Empire, which existed from approximately the 4th century to the fall of Constantinople in 1453. The Byzantine Empire inherited a mix of measurement systems from its Roman and Hellenistic predecessors, and over time, it developed its own conventions and standards for measuring length, weight, area, and volume. ### Key Aspects of Byzantine Units of Measurement 1.
Cana (unit) by Wikipedia Bot 0
Cana is a unit of measurement that is defined in the context of certain scientific and engineering fields, specifically in relation to measure angles. However, it is not commonly used or widely recognized compared to other units such as degrees or radians. If you meant something else by "Cana," or if you are referring to a specific context (e.g., astronomy, physics, etc.
Candlepower by Wikipedia Bot 0
Candlepower is a unit of measurement that indicates the luminous intensity of a light source in a specific direction. It is defined as the amount of luminous power emitted by a light source in a given direction per unit solid angle, typically measured in candelas (cd). One candela is roughly equivalent to the luminous intensity of a standard candle, hence the name "candlepower.
Carcel lamp by Wikipedia Bot 0
The Carcel lamp refers to a type of oil lamp designed by the Danish architect and designer Hans J. Wegner. The lamp gained recognition for its aesthetic appeal and functionality. Named after the Danish word for "prison," the Carcel lamp was traditionally used in prison settings due to its simple design and efficiency. The lamp typically features a glass reservoir for oil, which is fed through a wick to create light.
Delisle scale by Wikipedia Bot 0
The Delisle scale is a temperature scale that was developed in the 18th century by the French mathematician and physicist Joseph-Nicolas Delisle. It is based on the freezing and boiling points of water, but it measures temperature in a way that is inversely related to the more commonly used scales like Celsius or Fahrenheit. In the Delisle scale: - The freezing point of water (0°C) is 100 degrees on the Delisle scale.
Coomb (unit) by Wikipedia Bot 0
The coomb is a historical unit of measurement for dry volume, primarily used in agriculture, particularly in the UK. It is typically employed to quantify agricultural produce, such as grain, potatoes, or other dry substances. The exact volume of a coomb can vary regionally, but it is commonly defined as equivalent to 4 bushels. In terms of modern measurements, one bushel is approximately 35.24 liters, which means a coomb would be around 140.

Pinned article: ourbigbook/introduction-to-the-ourbigbook-project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
