The width of a human hair is 0.0018 cm.
A human hair typically has a width of about 70,000 to 100,000 angstroms.
the grain of zircon and it is the width of a human hair

Some transistors are as big as a bucket, and some are smaller as an average human hair's width.
Approximately 1 million atoms can fit across the width of a human hair.
You would need to line up about 2,500,000 aluminum atoms to match the width of a human hair. This is because the width of a human hair is typically around 70 micrometers, and an aluminum atom is about 0.28 nanometers in diameter.
1 micron = 10^(-6) metres. 1 millimetre = 10^(-3) metres = 10^3 x 10^(-6) metres = 10^3 microns = 1000 microns. Thus 0.1 millimetres = 0.1 x 1000 microns = 100 microns.
The human eye can typically see objects as small as 0.1 millimeters, which is about the width of a human hair.
The smallest object visible to the human eye is about 0.1 millimeters in size, which is roughly the width of a human hair.
Human hair varies in size greatly. A child's head hair can be as fine as 0.05mm. An adult's head hair can be as course as 0.25mm. Adult eye- brow hair can be as thick as 0.3mm. Hair is circular in shape, not flat like grass. Things which are circular or round in shape, do not have 'thickness', they have 'diameter'.The sizes above express the Diameter of Hair. In the Imperial system of measure, human hair varies between 0.002 inch & 0.010 inch Diameter.
This is estimated to be 100 microns. There are 1000 microns in a millimetre. So in millimetres, a human hair is approx 0.1 millimetres in width.
Transistors are made that are smaller than a human hair. Used as part of an integrated circuit chip, which may contain thousands of transistors.
