Convert 625 mg to kg.
svetlana [45]

Answer: 0.000625

Explanation:

If you don't know, one Milligram is equivalent to 0.000001 Kilograms. Hence, we'll multiply 625 by 0.000001.

With that being said, 625 times 0.000001 will equal to 0.000625.

Don't forget to add the units.

Milogram unit ⇒ mg

Kilogram unit ⇒ kg

Finally, your grand answer is 0.000625.

Titanium: to make the body of supersonic aircrafts because it is strong and corrosion resistant

Gold: to make jewelry because it is shiny and also corrosion resistant

Non-metals:

Nitrogen: to fill up chip packages because its molecules are unreactive

Helium: to fill up balloons because it is lightweight

Hydrogen: for generating electricity in hydrogen fuel cells. It is environmentally-friendly because it does not produce any greenhouse gas or toxic pollutants.

Fluorine: added in toothpaste for strengthening the teeth. It can also prevent cavities.
