Q:

# What is the formula to convert a mg/L concentration into a percentage?

A:

A concentration given in mg/L can be converted to a percentage by multiplying it by 0.0001, according to information provided by the University of California. Concentration refers to the amount of solute in a solution. When designated as mg/L, it denotes the mass in milligrams per liter of solution.

Concentration of a solute can also be represented as a percentage by dividing the mg/L concentration, which also means ppm or "parts per million," by 10,000 to get parts per 100, or percentage.

The ppm or mg/L notation is used more often because it is easier to comprehend. Percentages are used in cases when there are high concentrations of solute. Values given in ppm represent mass per mass concentration, while mg/L represents a mass per volume concentration.
