There are approximately 58,000 nanograms in a single grain of salt.
There are 1000000 nanograms in a milligram. Therefore there are 0.000108 milligrams in 108 nanograms.
1 gram is equal to 1,000,000,000 nanograms.
There are a million nanograms in a milligram. Therefore 270/1000000 is 0.00027 milligrams.

A single piece of salt is called a grain or a crystal.
Depends how big the grain of salt is.
There are 453,592,370,000 nanograms in one pound
A million nanograms.
There are 1000000 nanograms in a milligram. Therefore 2533 nanograms is 0.002533 milligrams.
There are 1000000 nanograms in a milligram. Therefore 1000 nanograms is 0.001 milligrams.
There are 1000000 nanograms in a milligram. Therefore 4 nanograms is 0.000004 milligrams.
There are 1000000 nanograms in a milligram. Therefore 25 milligrams will be 25,000,000 nanograms.
There are 1000 nanograms in a microgram. You have to multiply micro by 1000 to convert to nanograms. 10*1000 is 10,000 nanograms.
1,000,000,000,000 nanograms are in one kilogram.
There are 1000000 nanograms in a milligram. Therefore there are 0.000108 milligrams in 108 nanograms.
???????????????? 1 milligram = 1,000,000 nanograms So, for example, 5mg of Adderall equals 5,000,000 nanograms
"Molecules are microscopic in size, so it is pretty hard to guess how many are in a grain of salt. One grain is probably made up of millions of molecules." ^ I am sorry someone hated you enough to ignore over 100 years of crystallography, chemistry and physics knowledge advancements to give you that crappy cop out answer Depending on the average size of a tiny salt grain, there can be between to .3 to 2 quintillion salt molecules in a grain of sodium chloride salt. Quintillion = 10^18, or one billion times one billion.
