For example, some job postings on the Content Writers Group on Facebook are giving 10 ppw, or 10 paisa per word—roughly Rs 50 for a 500-word essay. While others offer less.
PPW is important because it gives an idea about how much you can expect to be paid for your work. It also shows what types of jobs are available for writers at that place and time. However, one must remember that this figure varies from place to place and year to year. In fact, a survey conducted by the University of Maryland in 2016 found that as much as 80% of the writing jobs listed on Freelancer.com were underpaying their writers.
They calculated the fair price of a written piece at $15.48 using a method called "copyright royalty." This means they took the cost of producing a book like The Help (which is relatively cheap to print) and divided it by the number of words in its two titles combined. This gives us an idea about how much each word is worth.
So if a writing job offers 3 ppw, then you can assume that it will take them three hours to write about 500 words. This means that you will be able to write more than one article while still making enough money to survive on.
PPM is an acronym for "pages per minute" in printing. In marketing, the term is used to indicate the speed of a printer. Printer manufacturers use the PPM value to compare one model's performance with that of another.
The PPM value is usually displayed as the maximum number of pages that the printer can print in one minute. For example, if a printer's PPM value is set at 100 pages per minute, then it can print up to 100 pages in one minute. Printers usually have a PPM rating printed on their box or sticker attached to the machine. If a printer's PPM value is not listed on its packaging, you can find it by asking the manufacturer or visiting websites such as PrintersRazing.com.
A common misconception is that printers print at a constant rate no matter how many pages they are printing. This is not true; instead, they print as fast as they are able to feed paper into the printer. The faster the paper moves through the printer, the more pages it will be able to print in one go.
PPM is most commonly defined as "Parts Per Million" on Snapchat, WhatsApp, Facebook, Twitter, and Instagram. The PPM feature allows users to add a filter to their photos or videos that displays percentages across the image. Users can choose from several different filters that change the appearance of their content with just one click.
10 ppm/10 ppmv denotes 10 parts in 1,000,000 parts, or 0.001%. 100 ppm/ppmv denotes 100 parts per million, or 0.01 percent. The abbreviation 1000 ppm/ppmv stands for 1000 parts per million, or 0.1 percent. It is important to be aware of which notation is being used, as the word "million" differs in each, that is, American and European notations. In America, a million refers to a thousand millions, or 10^6; but in Europe it refers to a billion, or 10^9.
The number 10 in front of the ppm symbol means that each million parts of air contains 10 particles per million parts of air. This can also be written as 100,000,000 particles per million particles. A particle is any atom or molecule that has an atomic mass greater than 5.5 u. In this case, the only elements present in the atmosphere are oxygen (16 g/mol) and nitrogen (28 g/mol). A mole of either of these gases contains 32 grams of atoms or molecules. Therefore, each mol of gas contains about 10^6 particles.
In conclusion, 10 ppm means that there are 10 million particles per million particles of air, or 100,000,000 particles overall. This is such a small number that it can be written as a percentage: 0.001%.
