A measuring unit for constituents in water. Constituents in water are often measured in very small units. One microgram per liter equals one part per billion.
(ug/l) a measure of the amount of dissolved solids in a solution in terms of micrograms of solid per liter of solution; Equivalent to part per billion in water or 1ug/l=1ppb
one microgram per liter corresponds to one penny in $10,000,000 (same as parts per billion or ppb).
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 to one billion micrograms.
A unit that expresses the concentration of a substance in a solution. A microgram per liter is one one-millionth of a gram of substance per liter of solution. A ug/L of sugar in water is about the same as a teaspoon of sugar in 2,100,000 gallons of water. For low concentrations in water, a microgram per liter is about the same as a part per billion (ppb).
A unit expressing the concentration of constituents in solution as weight (micrograms) of solute per unit volume (liter) of water; equivalent to one part per billion in most stream water and ground water.
one part per billion by weight.
A unit expressing the concentration of chemical constituents in solution as mass (micrograms) of solute per unit volume (liter) of water. One thousand micrograms per liter is equivalent to 1 milligram per liter.
The weight of a substance measured in micrograms contained in 1 liter. It is equivalent to 1 part per billion in water measure.
