Yes. For examples, a nanometer is 10-9 meters, or 1/1000 of a micron.
millimeter
There are many units of measure smaller than a foot. In standard US measure 12 inches equal one foot.
Convert both to the same unit, then compare. 1 mm = 1000 micron.
Unit of measurement 1000 times less than the millimeter is the micrometer. Unit of measurement 1,000,000 times less than the millimeter is the nanometer.
It is measured in Atomic Mass Unit i.e. molecular mass unit (u - micron) 1u = 1.66x10^-27 kg
Yes there most certainly is, however you may not have the equipment to measure it. 0.001 mm is a micron. 0.000001mm is a nanometre. 0.000000001mm is a picometre. See angstrom, femto and attometre also.
It is a micrometre; one millionth of a metre.
millimeter
There are many units of measure smaller than a foot. In standard US measure 12 inches equal one foot.
a centimetre (10^-2) or millimetre (10^-3). maybe even as small as a micron (10^-6)
Since 62 is a bigger number than 7, and you are measuring the same unit, 62 microns is bigger than 7 microns.
division
Convert both to the same unit, then compare. 1 mm = 1000 micron.
Unit of measurement 1000 times less than the millimeter is the micrometer. Unit of measurement 1,000,000 times less than the millimeter is the nanometer.
Micron (the correct word is micrometer) is not a particle; the micrometer (μm) is a unit of measure for length. 1 μm = 10-6 m
A gsm is a measure of mass per unit area while a micron is a measure of length or distance. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.
1 micron IS the unit in this case. 1 micron is the same as a micrometer - a millionth of a meter (or a thousandth of a millimeter).
