The number of milligrams per kilogram is exactly the same as the number of parts per million. In other words, 1 mg/kg = 1 ppm.
Know MoreAccording to Engineering Toolbox, parts per million, or ppm, is a term used to measure a small number of particles in air, water or bodily fluids. For example, a value of 10,000 parts per million refers to 1 percent of the solution, as 10,000 is 1 percent of 1 million. Similarly, 10,000 mg/kg x 1 g/1000 mg x 1 kg/1000 g = .01, showing that 10,000 mg/kg also represents 1 percent of the total solution. There is a one-to-one ratio between the number of parts per million and mg/kg.
Learn more about MeasurementsThe number of milligrams per millimole of a given substance is equivalent to that substance's molar mass. A millimole is one thousandth of a mole, and moles are a measure of the amount of substance, not mass. Therefore, the number of milligrams in a millimole varies depending on the substance being measured.
Full Answer >There are one million milligrams in a kilogram. A milligram is the smallest metric measurement and is equal to .001 of a gram. It takes 1,000 milligrams to equal 1 gram and 1,000 grams to equal a kilogram.
Full Answer >One kilogram is roughly equivalent to 2.2 pounds, so multiplying 62 by 2.2 is 136.4. The result will slightly vary depending on the number of decimal places in the pound multiplier. For example, a kilogram may also be multiplied to 2.204622, which is its pound equivalent up to the sixth decimal resulting in 136.6866 rounded off to the fourth decimal.
Full Answer >Because 1 kilogram is equal to 2.2 pounds, converting 178 pounds to kilograms requires dividing 178 pounds by 2.2 pounds per kilogram. The equivalent of 178 pounds is approximately 80.9 kilograms.
