Colorado Correction Industries oversees approximately 60 inmate work programs. Jailbirds at Fremont County Jail, for example, build fiberglass-sealed canoes. They use scraps from the prison's furniture shop and sell the canoes for around $1500. Other Colorado programs help craft those ubiquitous college dormitory desks and bookshelves. 9. Artsy knick knacks San Quentin State Prison in California is a scary place. It houses some of the most menacing criminals in the nation, and it's home to the largest death row in the United States. But at least it has a gift shop. There, you can buy convict-made music boxes, drawings, and paintings.
The answer is 0.001. We assume you are converting between microgram/milliliter and nanogram/millilitre. The SI derived unit for density is the kilogram/cubic meter. 1 kilogram/cubic meter is equal to 1000 mcg/ml, or 1000000 ng/ml. Note that rounding errors may occur, so always check the results. Use this page to learn how to convert between micrograms/millilitre and nanograms/milliliter. Type in your own numbers in the form to convert the units!
Since one ppm means 1 microgram per gram, the number of micrograms present will be the same as the number of grams of solvent. Thus, if a substance is dissolved in one cubic meter of sulfuric acid at a concentration of one ppm, there are 1.85 million micrograms present. microgram is one-millionth of a gram. Thus, a concentration of one ppm means there is one microgram of a substance per gram of solvent. Find the mass of the solvent contained in one cubic meter. To do this, look up the specific gravity of the solvent.
