Tag: Concentration units

In chemistry, a 10% glucose in water by mass solution contains exactly 10 grams of glucose for every 100 grams of the total solution. This fundamental metric is used to express the concentration of a mixture accurately and is commonly utilized in various scientific and industrial applications.

A microgram (μg) is a unit representing one-millionth of a gram. When measuring quantities of substances so miniscule, especially in contexts like trace minerals or contaminants in food and water, scientists use the more convenient unit known as parts per million (ppm), but what is ppm in nutrition specifically? This guide explores its scientific meaning and practical implications for your diet.
