Q: A: ### Quick Answer

**To convert parts per million to milligrams per liter, use the conversion factor of 1 ppm = 1 mg/L.** This means that 1 part per million is equal to 1 milligram per liter.

Milligrams per liter is an important unit of measure that illustrates the concentration of dissolved substances. This unit of measure is a ratio of mass or weight per volume. This differs from parts per million, which instead is a measure of weight per weight or mass per mass.

The unit parts per million is used when there is a very low concentration of a solution. One gram of a solution in 1000 milliliters equals 1000 parts per million. When the mass of the solution is reduced to 1/1000 of a gram in 1000 milliliters, this equals 1 part per million. Because 1000 milliliters equals one liter, 1 part per million is 1 milligram per liter.

One part per million only equals 1 milligram per liter in the event that the solvent is water. This is a direct result of water's gravity, which is very close to one. When the solute, or the substance dissolved in the solution, is less than 1 percent, it can be assumed that the liter of water weighs 1,000 grams, which is equal to 1 million milligrams.

## How do you convert 123 pounds to kilograms?

A:

Full Answer >**There are three ways of converting 123 pounds to kilograms; using an online pound to kilogram calculator whereby it automatically converts the pounds to kilograms, dividing the 123 pounds by a conversion factor of 2.2 or multiplying the 123 pounds by a conversion factor of 0.453.**When 123 pounds is multiplied by 0.453, it gives 55.719 kg, and when it is divided by 2.2, it gives 55.91 kg. On rounding off, the answer becomes 56 kg.Filed Under:
