Microgram (µg) is a metric measurement used for presenting the unit of mass. A microgram or so-called microgramme is equal to one millionth (e.g., 1×10-6) of a gram. According to the International System of Units, the combined symbol of "micro" and "gram" is μg. In everyday use, the recommended microgram symbol in the United Kingdom and the United States when conveying medical information is "mcg." The prefix symbol in In μg, for "micro," is the Greek letter μ (Mu).
The U.S. Food and Drug Administration (FDA), along with the United States-based Institute for Safe Medication Practices (ISMP), recommend that the microgram symbol "μg" is better not to use when conveying medical information. Because of the risk that the prefix μ (micro-) may be misread as the prefix m (milli-). That overall results in a thousandfold overdose, so instead, the non-SI symbol "mcg" is recommended for use. In the U.K., the "μg" symbol is the widely recognized way of identifying micrograms. The "microgram symbol" is encoded by Unicode as U+338D ㎍ Square Mu G ❰ ㎍ ❱.
The microgram symbol is used either like "mcg" or "ug" since the µ symbol is not commonly accessible on most keyboards. The micro character (µ) is a Greek letter, which means - small. Simultaneously, micrograms are usually identified as mcg (μg). "µg" is the right symbol for the metric measurement; for example, µg = mcg = microgram = 1/1,000 of a milligram = 1/1,000,000 of a gram. Hence, a microgram is 1/1,000 of a milligram or 1/1,000,000 of a gram.
Sometimes the letters "mcg" is also used as an abbreviation for microgram symbols. Due to the symbol "µ" being typographically inaccessible, i.e., one cannot type the character on a keyboard, other versions were later devised, two of which are currently widely used signs - "mcg" and "ug."
Microgram (i.e., a millionth of a gram) is signified es "µg," where the letter "g" is a recurring character, but the "µ" can be typed on a german Apple or MacBook keyboard pressing the "Alt" and the "m" key at the same time.
The letter "μ" is widely popular in different fields of science. For instance, the "μ" symbol may appoint a coefficient of friction, and population means in statistics, magnetic permeability in physics, and micrometer or micron in measurement. There are several ways to quickly insert any Greek or Latin letter into an M.S. Word document. Some of the most useful methods for a microgram, micro sign, or mu letter are shown below. So. to insert them in a Word document, follow the way shown below:
You should use the Symbol font since it is convenient when you want to insert rare symbols, and it works only for Greek and Latin letters. Anytime you type the text in the M.S. Word document, you can switch to the "Symbol font" to use the corresponding Latin letters to enter Greek letters:
*Note: The above method works only for inserting one letter. However, if you wish to insert more than one symbol, you will need to repeat these same steps for each insertion. After inserting one letter using the "Symbol font," the next character can be entered using the previous font. Also note that if you press Ctrl+Shift+Q twice, M.S. Word will not switch to the previous font, so the Symbol font won't stop to work after the first inserted symbol.
