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?
The Imperial ton, also known as the long ton, is a unit of mass used primarily in the United Kingdom and other Commonwealth countries. One imperial ton is equal to 2,240 pounds, or approximately 1,016.05 kilograms. This makes it heavier than both the US ton (short ton, 2,000 pounds) and the metric tonne (1,000 kilograms).
The imperial ton originated in the British Imperial system and dates back to times when goods were transported in large barrels or "tuns." These barrels typically held about 2,240 pounds of product—hence the origin of the long ton.
The unit was officially adopted as part of the British Imperial system in the 19th century. Though it's no longer widely used in trade or industry, it still appears in naval shipping, mining, and some historical references in the UK.
How Is the Imperial Ton Used: Today, the imperial ton is used less frequently due to the global adoption of the metric system. However, it remains relevant in:
1 µg = 0 Imperial ton
Let’s say you want to convert 100 µg to Imperial ton.
Using the formula:
100 × 0 = 0 Imperial ton
So, 100 µg is approximately 0 Imperial ton.
