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.
Know MoreConcentration 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.

Full Answer >In order to express a number as a percentage, one converts it from a mixed number or fraction to a decimal, moves the decimal point two places to the right and adds the percent sign. By definition, percentage is the rate per 100. Moving the decimal point is a shortcut for multiplying by 100.
Full Answer >Converting a ratio to a percentage involves using division to change the fractional or descriptive ratio to a portion out of 100. For example, the ratio of 1 in 4, which can also be expressed as 1/4, would convert to a percentage through the division of 1 by 4 and then multiplying by 100, equaling 25 percent.
Full Answer >To convert a percentage to a ratio, write out the percentage number as a fraction, reduce the fraction to its simplest form and convert the new fraction to a ratio by replacing the slash mark with a colon. Converting a percentage to a ratio takes only a few minutes and requires paper and a pencil.
