Detailed explanation-1: -It is usually expressed as a concentration in parts per million (ppm) or micrograms per liter (mg/L). The concentration can also be expressed as percent saturation, where saturation is the maximum amount of oxygen that can theoretically be dissolved in water at a given pressure and temperature.
Detailed explanation-2: -Oxygen is measured in its dissolved form as dissolved oxygen (DO). The results of this measurement are usually expressed as milligrams of dissolved oxygen per liter of water (mg/L, parts per million, or ppm).
Detailed explanation-3: -Dissolved oxygen is usually reported in milligrams per liter (mg/L) or as a percent of air saturation. However, some studies will report DO in parts per million (ppm) or in micromoles (umol). 1 mg/L is equal to 1 ppm.
