2010年12月3日 · The 1 ppm = 1mg/kg is simply a concentration measurement. This is done after the volume has been converted to mass. Sure you could have 99 boxes of feathers and one box of lead, that concentration of lead would be higher than 1 …

2006年5月30日 · A forum page for Convert-Me.Com - online units conversion. View topic - ppm to kg?

2006年7月11日 · so multiply ug/kg by 1000 to get ppm (1 ug/kg = 1000 ppm) assuming that you mean ppm by weight (mass) John

2006年7月23日 · However, if it is a dilute solution in water, it will weigh very close to 1 kg, and mg/kg is ppm. Guest Top.

2008年12月2日 · 840 ppm = 840 mg/kg or 0.840 g/kg Since 1 lb = 0.4536 kg 0.840 g/kg x 0.4536 kg/1 lb = 0.381 g/lb. Guest Top.

2011年5月9日 · There are 1 million mg in 1 kg, so 15 mg/kg IS 15 ppm (by weight). Note that ppm is a vague, poorly defined term. It can express a ratio by weight, volume, or mole fraction. Which "flavor" of ppm is meant should ALWAYS be specified. If you meant ppm by volume or mole fraction, there is not enough info.

2004年4月21日 · 0.5 mg/kg = 0.5 ppm = 500 ppb = 500 000 ppt. The difference between 1 mg and 1 kg is 1 000 000 (one million), so 1 mg/kg is one part per million (1 ppm). To convert from parts per million (ppm) to parts per billion (ppb), simply multiply by 1000 (this works because the fractions 1/1 000 000 and 1000/1 000 000 000 are equivalent).

2005年8月17日 · Since mg and kg are 10^6 apart, 5 ppm = 5 mg/kg, or 0.5 mg/100 g. Guest Top. More info.

2012年8月2日 · The conversion for PPM are as follows: 1 Part Per Million (ppm) = 1 milligram per liter (mg/L) = 1 milligram per kilogram (mg/kg) = 1 microgram per gram (µg/g) = 0.0001 percent (%) = 0.013 fluid ounces per 100 gallon water I hope this is what you were looking for

2008年8月27日 · THere are 1000 milligrams (mg) in a gram, and 1000 grams in a kilogram (Kg). Therefore there are 1 million milligrams in 1 Kg. Therefore .115 mg is 0.115ppm (parts per million).
