If your talking about vacuum 500 microns of Hg is lower.
500
It is 0.000039 inches, approx.
There are 1000 microns in a mm. There are 5000 microns in 5 mm
millionths of what, if inch then 2.54 microns if metre then 100 microns
150 microns is about 0.005905512 inches.
500 to 0 microns
The answer depends on whether 100 is more or less than 500!
8000-500=7500.
500
15 * 500= 7500
It is: (VII)D which means 1000*7+500 = 7500
