how many ppm in 1 mg?
91563
PPM = parts per million One thousanth of a gram is one milligram and 1000 ml is one liter, so that 1 ppm = 1 mg per liter = mg/Liter. PPM is derived from the fact that the density of water is taken as 1kg/L = 1,000,000 mg/L, and 1mg/L is 1mg/1,000,000mg or one part in one million.

Parts per million and parts per billion may be converted from one to the other using this relationship: 1 part per million = 1,000 parts per billion. For water, 1 ppm = approximately 1 mg/L (also written as mg/l) of contaminant in water, and 1 ppb = 1 ug/L (also written as ug/l).

Parts per million (ppm) is the number of units of mass of a contaminant per million units of total mass. More: ppm (or ppmm) is used to measure the concentration of a contaminant in soils and sediments.

The unit is abbreviated as tsp. Convert Milligrams (mg) to Teaspoons (tsp): 1 mg is approximately equal to 0.0002 tsps. One milligram is a relatively small quantity of table salt. A mere one-teaspoon of granulated salt contains some 2325 milligrams.

Hence to make a 0.1 mM solution , you will need to dissolve 39.4 mg of DPPH in methanol/ethanol. A simple way to check is for 1 M in 1000 mL you need 394 g, for 1 mM you need 394 mg, so for 0.1 mM you would require 39.4 mg. However, I would suggest making a higher stock 10 mM and then dilute it before use.

The conversion factor would be 1 mg/l = 3 NTU = 1 ppm based on 1 mg/l = 1 ppm. Each application may have a different conversion factor due to the varying response of the turbidity instrument based on the particulars of the application and samples.

All Answers (16) 1 ppm = 1 part /106 part; 1% = 1/100; so 1% = 1/100 x 106 = 104 ppm. If each element is available in wt%, just multiply with 104 to get the concentration numbers in ppm.
