liter (l or L) This term is generally used when measuring a volume of liquid. A liter is slightly larger than a quart; about 3.8 liters are in a gallon. milliliter (ml) A milliliter is one one-thousandth (1/1,000) of a liter.
micrograms per liter (mg/L) One microgram of a substance
dissolved in each liter of water. This unit is equal to parts
per billion (ppb) since one liter of water is equal in weight ...
milligrams per liter (mg/L) A measure of concentration of a dissolved substance. A concentration of one mg/L means that one milligram of a substance is dissolved in each liter of water.
The amount of oxygen (measured in mg/L) that is consumed in the oxidation of organic and oxidasable inorganic matter, under test conditions. It is used to measure the total amount of organic and inorganic pollution in wastewater.
1 nanogram per liter (ng/L) =1 part per trillion (ppt) = 1000 parts per quadrillion (ppq) *
1 picogram per liter (pg/L) = 1 part per quadrillion (ppq) *
1 grain per gallon (gpg) = 17.1 milligrams per liter (mg/L) ...
Chemical Oxygen Demand (COD): The amount of oxygen (measured in mg/L) that is consumed in the oxidation of organic and inorganic matter, under test conditions.
Picocuries Per Liter pCi/L): A unit of measure for levels of radon gas; becquerels per cubic meter is the metric equivalent.
Piezometer: A nonpumping well, generally of small diameter, for measuring the elevation of a water table.
Picocuries per liter (pCi/L)
A unit of measure for levels of radon gas.(1)
Pollutant Standard Index (PSI)
Measure of adverse health effects of air pollution levels in major cities.(1) ...
Effects Range-Low (ER-L)
In aquatic systems, concentrations of contaminants that below which adverse biological effects would rarely occur.
Total Dissolved Solids (TDS): Concentration of total dissolved solids (TDS) in groundwater expressed in milligrams per litre (mg/L), is found by evaporating a measured volume of filtered sample to dryness and weighing this dry solid residue.
Milligrams per liter (mg/L)
The measure of concentration used in the measurement of chemicals in fluids. This is the most common way to present a concentration in water and is roughly equivalent to parts per million.
Million-Gallons Per Day ...
Vapor Density: The vapor density is expressed in grams per liter (g / L) and is comparedto the density of air (air=1).
number of parts of a chemical found in one billion parts of a solid, liquid, or gaseous mixture. Equivalent to micrograms per liter ( m g/L).
ppm, parts per million ...
Dissolved Oxygen: Oxygen dissolved in water. The amount depends on temperature of the water, plant photosynthesis, plant and animal respiration, and physical aeration caused by tumbling. Measured in parts per million (mg/L).
