centic

Centic is a unit of measurement used to quantify the concentration of a substance in a solution. The term is derived from the Latin word "centum," meaning hundred, and the Greek word "kentos," meaning hundred. The centic is defined as the number of grams of a solute per 100 grams of a solution. This unit is particularly useful in chemistry and biology for expressing the concentration of solutes in various solutions, such as blood or other biological fluids.

The centic is often used in medical and biological contexts to describe the concentration of electrolytes, proteins, or other substances in bodily fluids. For example, the sodium concentration in blood plasma is typically expressed in centics, where a value of 140 centics means that there are 140 grams of sodium per 100 grams of blood plasma.

While the centic is a straightforward and intuitive unit for expressing concentration, it is less commonly used in modern scientific literature compared to other units such as molarity or molality. However, it remains a valuable tool for certain applications, particularly in fields where the mass-based concentration of a substance is of primary interest.
