You need to contain a mass within a volume; not a distance!
If the question was how many mg are in one km cubed, you will the density of the material.
density= mass/volume so (density) *(volume)=mass.
Be careful and use proper units.
1 km = 1000 meters 1 meter = 0.001 km
To convert from km to ft, multiply by 3280.84 1 km is equal to 3280.84 ft
Since there are 1.609 km. in one mile, in three miles, there are 4.827 km. 3 mi* 1.609344 km 1 mi = 4.828032 km
1 mg = 1000 mcg so 6 mg = 6*1000 = 6000 mcg. Simple!
4.6 if you are talking about 1 mile to kilometer (Mr.ButtonBasher)
1 mg is equal to 1000 mcg
Accordingly, 1 ml = 1/7.5 mg = 0.133 mg
15 dg equal how many mg
1 gr(grain) is equal to about 1/64th of a mg so 1 mg(milligram) is equal to 0.0154323584 gr(grains)
1 milligram (mg) is equal to 0.001 units.
0.001 g = 1 mg
1 milligram is equal to 1000 micrograms.
1000
1000MG
0.000001
1 kilometer is equal to approximately 0.621 miles.
your question doesn't make sense. you are trying to go from a unit of weight to length. If you you mean "how many mm are in 1 km?", then there are 1,000,000 in 1 km
