A microgram (mcg) is a metric unit of mass equal to one-millionth of a gram. It’s one of the smallest standard units of mass, commonly used in medical, nutritional, and scientific settings where extremely small quantities matter.
The term comes from the Greek word mikros meaning “small” and “gram,” the base metric unit for mass. Its official SI symbol is µg. However, in medical practice especially in the U.S. mcg is used to prevent confusion with mg (milligram), which is 1,000 times larger.
How Is Microgram Used?
A US ton, also known as a short ton, is a unit of weight used primarily in the United States. One US ton equals exactly 2,000 pounds or approximately 907.1847 kilograms. It's commonly used in industries like freight, construction, and agriculture to measure large quantities of weight, mostly bulk goods. The US ton is not the same as the imperial ton (also called the long ton) or the metric tonne, so it's important to understand the distinction when converting.
The concept of a "ton" comes from the old term "tun," which referred to a large barrel used for shipping wine. Over time, the word evolved into a unit of weight. The United States standardized the ton to 2,000 pounds, distinguishing it from the British imperial long ton (2,240 pounds) and the metric tonne (1,000 kg).
Today, the US ton remains part of the customary system of units used throughout the country.
How Is the US Ton Used: The US ton is a practical unit for expressing large-scale weight, especially in commercial, agricultural, and industrial sectors. It's widely used for:
1 µg = 0 US ton
Let’s say you want to convert 100 µg to US ton.
Using the formula:
100 × 0 = 0 US ton
So, 100 µg is approximately 0 US ton.
