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.
By unit of length and mass and conversion ,we can say that km and mg belong to different categories and chence cant be converted into each other
Milligram is a unit of weight and kilometer is a unit of length. We cannot these 2 fundamental units of measurement.
1,000,000 milligrams
7,000,000 mL
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)
0.001 g = 1 mg
1 km is about 0.62 mile
1 mg equates to 0.015432 grains.
1 mile equals to 1.609344 km
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
