since 1000 mm =1 m, then .015 mm = .015/1000 = .000015 m

21%
I doubt this has any use... but here goes... Divide by 1000000000000. So 15 / 1000000000000 = 0.00000000015 kilometers.
air is made of 19.98 percent oxygen 79 percent nitrogen and 2 percent carbon
20 Percent.
The percent of oxygen in dry air is approximately 21%.
78 percent Air is mostly gas The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen.
Troposphere is name of the layer. It contains 75 percent of the air.
A tiny amount of air.

oxygen! There is 21 percent oxygen in inspired ( the stuff you breath in) air and 13 percent in expired(the stuff you breath out)
