There can be no equivalenece.
A becquerel is the SI derived unit of radioactivity. It is defined as the activity of a quantity of radioactive material in which one nucleus decays per second. It is a measure in inverse second, s-1 and so has dimensions [T-1].
A milligram is a measure of mass, whose dimension is [M].
The two have different dimensions and according to basic principles of dimensional analysis, conversion from one to the other is not valid.
0,25 of what ? gram, kilo, ... ? I'll have to guess 0,25 gram are 250 milligram
There are 1000 micrograms in a milligram. You multiply by 1000 here. 0.0125 milligrams is 12.5 micrograms.
No. 45 mg equals 0.045 gms, since each milligram equals 10-3 gms.
A grain of salt does not equal 1 milligram; rather, it is approximately 58 milligrams. This discrepancy arises from the historical use of the grain as a unit of measurement in the apothecaries' system, where 1 grain is defined as 1/7000th of a pound. In contrast, the metric system defines 1 milligram as 1/1000th of a gram. Therefore, a grain of salt is significantly larger than 1 milligram.
One gram equals 1000 milligrams.
1000 milligram equals a gram
There are 1000mcg (micrograms) per milligram.
No.
1 / 0.125 = 8Of anything.
505mg (milligram) equals 0.505kg (kilogram)
1mg, or milligram, equals 1000mcg, or one thousand micrograms.So 150mcg is 0.15mg (about one-sixth of a milligram).
You have 1000 micrograms in a milligram. Therefore you have to divide by 1000 here. 100/1000 is 0.1 milligram.
There are 1000 micrograms in a milligram. Therefore, you have to multiply milligrams by 1000. 2x1000 is 2,000 micrograms.
milligram
.1 milligrams is 1/10th of 1 milligram. Therefore, it would take ten .1 milligrams to equal 1 milligram.
1000 ppm is equivalent to 1 milligram per milliliter.
5000 mg = 5 grams1 milligram = 0.001 grams
