An ounce (oz) is a unit of weight commonly used in the United States and a few other countries that follow the imperial system. It plays a vital role in cooking, shopping, postal services, and precious metals measurement. One ounce is approximately equal to 28.35 grams.
There are two main types of ounces:
The word "ounce" comes from the Latin word "uncia," meaning one-twelfth. Historically, it represented 1/12 of a Roman pound. Over time, different standards emerged, with the avoirdupois and troy systems becoming the most widely used.
How Is the Ounce Used: The ounce is used in various industries and everyday tasks. Here's how it shows up in real life:
The ounce may seem like a small unit, but it’s incredibly versatile. From kitchen scales to postal counters to precious metal markets, it helps measure weight where precision matters.
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?
1 oz = 28349523.125 µg
Let’s say you want to convert 100 oz to µg.
Using the formula:
100 × 28349523.125 = 2834952312.5 µg
So, 100 oz is approximately 2834952312.5 µg.
