200 microgram is bigger than 2000 nanogram. This is because 1 microgram is equivalent to 1000 nanograms.
1 microgram = one part of one million part of gram = 0.000001 gram = 10 -6 gram
There are approximately 3.82 x 10^13 atoms of uranium in 1 nanogram of uranium.
0.001 grams equals 1 milligrams (mg). And 0.001 milligrams in 1 microgram (mg), therefore 0.000001 grams (or 1 x 10-6) in 1 microgram. There are therefore 100,000 micrograms in a gram and in context 1000 milligrams in a gram.
10 mg is equal to 10,000 micrograms (ug) because 1 mg is equal to 1,000 micrograms.
200 microgram is bigger than 2000 nanogram. This is because 1 microgram is equivalent to 1000 nanograms.
1 ng is 0.04 IU. So, to convert 12.5 microgram, multiply 12500 nanogram with 0.04; the required answer is 500 IU
10-6 grams
'Nano-' denotes a fraction of one billionth (10-9)A nanogram (ng) is, therefore, 10-9gor one billionth of a gram. This can be written as a unit in the 9th decimal place: 0.000000001g.Similarly:10-6g = 1 microgram (µg)...10-12g = 1 picogram (pg)10-15g = 1 femtogram (fg)and so on.
There are approximately 3.21 × 10^14 gold atoms in 1 nanogram of gold. In 1 pictogram of gold, there are approximately 3.21 × 10^8 gold atoms.
1 microgram = one part of one million part of gram = 0.000001 gram = 10 -6 gram
There are approximately 3.82 x 10^13 atoms of uranium in 1 nanogram of uranium.
1*10^-7 grams, or 1/10 microgram
I think your question should read 'How many nanogram in 1 mg?' A nanogram is 10-9 of a gram, and a milligram is 10-3 of a gram. So your question becomes how many times will 10-9 fit into 10-3?. For which the answer is obviously 106. or 1 million.
1 milligram = 1000 micrograms 10 milligrams = 10000 micrograms
Giga means 10^6 or 1,000,000 grams. Micro means 10^-6 or 0.000001 grams. Therefore A gigagram is a trillion tiles (1,000,000,000,000) times bigger than a microgram.
10 grams = 10,000,000 (ten million) micrograms
