Units of amount typically refer to the standardized measurements used to quantify the amount of a substance or material in various contexts. These units can vary depending on the type of measurement being made, such as mass, volume, or quantity of items. Here are some examples: 1. **Mass**: - Grams (g) - Kilograms (kg) - Milligrams (mg) - Pounds (lb) 2.
The unit of luminous energy is the "lumen second" (lm·s). Luminous energy refers to the total amount of visible light emitted by a light source, taking into account the sensitivity of the human eye to different wavelengths of light. It is derived from the measurement of luminous flux (in lumens) over a period of time (in seconds).
Photometry is the science of measuring visible light in terms of its perception by the human eye. It involves assessing the intensity, quantity, or distribution of light. The key units of photometry include: 1. **Lumen (lm)**: The unit of luminous flux. It measures the total amount of visible light emitted by a source in one second. 2. **Lux (lx)**: The unit of illuminance, which measures how much luminous flux is spread over a given area.
Units of quality by Wikipedia Bot 0
"Units of quality" can refer to various measures or metrics used to assess the quality of a product, service, or process in different fields. Here are a few interpretations based on context: 1. **Manufacturing and Production**: In manufacturing, units of quality might refer to the number of items produced that meet specific quality standards or defect rates. For example, a company might monitor the number of defective units per thousand produced to assess quality.
Units of rate by Wikipedia Bot 0
The "units of rate" refer to the specific measurements used to express a rate, which is a quantity divided by time or another denominator. Rates are commonly expressed in various forms depending on the context. Here are a few examples: 1. **Speed or Velocity**: The rate of distance traveled over time, typically expressed in units like: - meters per second (m/s) - kilometers per hour (km/h) - miles per hour (mph) 2.
Call-second by Wikipedia Bot 0
"Call-second" isn't a widely recognized term in mainstream contexts as of my last knowledge update in October 2021. However, it could refer to various things depending on the industry or context: 1. **Telecommunications**: It might refer to a metric or measurement in call centers or telecommunications, indicating the second call in a series or the time it takes for the second call to be answered.
Centimorgan by Wikipedia Bot 0
A centimorgan (cM) is a unit of measure used in genetics to describe the distance between genes on a chromosome. It reflects the likelihood of recombination (or crossing over) occurring between two genes during meiosis, the process of cell division that produces gametes (sperm and egg cells). Specifically, one centimorgan corresponds to a 1% chance that a crossover will occur between two genes during meiosis.
Darcy (unit) by Wikipedia Bot 0
The Darcy is a unit of permeability used in the fields of soil science and petroleum engineering to measure the ability of a material to allow fluids to flow through it. It is named after the French engineer Henry Darcy, who is known for his work on fluid flow through porous media.
Dobson unit by Wikipedia Bot 0
A Dobson Unit (DU) is a measure of the amount of ozone in a column of the Earth's atmosphere. It is defined as the number of ozone molecules in a column of air that is 1 square centimeter in cross-section and extends from the surface of the Earth to the top of the atmosphere, weighted to a standard pressure and temperature. Specifically, 1 Dobson Unit corresponds to a total column of ozone that would create a layer of pure ozone 0.
Grain per gallon by Wikipedia Bot 0
Grain per gallon is a measurement used to describe the concentration of a substance, typically a solute, in a liquid solution. It is often used in contexts such as brewing, winemaking, and water treatment to quantify the amount of dissolved solids or other compounds in water. 1. **Brewing and Winemaking**: In brewing or winemaking, grain per gallon can refer to the amount of fermentable sugars or other solids extracted during the process.
IEEE Std 260.1-2004, also known as "IEEE Standard for the Representation of Numbers in Information Technology," is a standard established by the Institute of Electrical and Electronics Engineers (IEEE). This standard defines the representation of numbers used in various areas of information technology, including computer systems and data transmission. Specifically, IEEE Std 260.
The International Yard and Pound (IYP) is a system of measurement that defines the yard and pound in a way that is standardized across multiple countries. It is based on the definitions adopted in 1959 by countries that are members of the Commonwealth of Nations as well as the United States. In the International Yard and Pound system: - **One yard** is defined as exactly **0.9144 meters**. - **One pound** is defined as exactly **0.
Per cent mille by Wikipedia Bot 0
Per cent mille, often written as "permille" (‰), is a unit of measurement that represents parts per thousand. It is similar to the concept of percentage, where percentage means parts per hundred, but permille is scaled to a base of one thousand. In mathematical terms, 1 permille is equal to 1/1000 or 0.1%. It is often used in contexts such as measuring concentrations (e.g., in chemistry) or in statistics.
Potrzebie by Wikipedia Bot 0
"Potrzebie" is a fictional word created by cartoonist Al Capp and is best known from his comic strip "Li'l Abner." In the context of the comic, "Potrzebie" refers to a humorous and nonsensical concept representing a person's peculiar and often irrational needs or desires. The term has been adopted in various humorous and satirical contexts to express the idea of something that is needed but may not have a clear or practical application.
Standard drink by Wikipedia Bot 0
A standard drink is a measure used to quantify the amount of pure alcohol in an alcoholic beverage. The definition of a standard drink can vary by country, but it generally contains about 14 grams (0.6 ounces) of pure alcohol. Here are some common examples of what typically constitutes a standard drink in the United States: - **Beer**: About 12 ounces of beer (with around 5% alcohol by volume).
Units of textile measurement refer to various standards used to quantify the dimensions and qualities of textiles, fabrics, and garments. Here are some common units and terms used in textile measurement: ### Fabric Width: - **Inches**: Commonly used in the U.S. for measuring the width of fabric. - **Centimeters**: Often used in many other countries to measure fabric width. ### Fabric Length: - **Yards**: Commonly used in the U.S.
Wool bale by Wikipedia Bot 0
A wool bale is a compressed package of raw wool that has been sheared from sheep, typically after the shearing process. This raw wool is cleaned, sorted, and compacted into bales for easier handling, storage, and transportation. Wool bales are often tightly wrapped and can weigh anywhere from 50 to 100 kilograms (approximately 110 to 220 pounds) depending on the type of wool and the standards used by the producer or organization.

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.
