A micron is one millionth of a meter and therefore one thousandth of a millimeter.
There are one million millimeters in a kilometer, so a millimeter would represent one millionth of a kilometer.
A micrometer is one millionth of a meter, a millimeter is one thousandth of a meter. So there are one thousand micrometers in a millimeter.
A 'micrometer' is a unit of length equal to one thousandth (10 -3) of a millimeter or one millionth (10 -6) of a meter. [For your information, - A 'nanometer' is a unit of length equal one thousandth (10 -3) of a micrometer, one millionth (10 -6) of a millimeter or to one billionth (10−9) of a meter].
1 nanometer = 1/1,000,000 mm which is one one-millionth of a millimeter or one one-billionth of a meter.
One millionth of a millimeter
A micron is one millionth of a meter and therefore one thousandth of a millimeter.
One ten millionth of a millimeter. A millimeter is smaller than a meter, and a ten millionth of a millimeter is obviously smaller than a hundredth of a meter.
There are one million millimeters in a kilometer, so a millimeter would represent one millionth of a kilometer.
A micrometer is one millionth of a meter, a millimeter is one thousandth of a meter. So there are one thousand micrometers in a millimeter.

Nanostructure is structure on a scale of nanometers. One nanometer is one billionth of a meter, or one millionth of a millimeter.
Actually, a millimeter is one-one thousandths of a meter, a nanometer is one-one millionth of a meter...
Do you know what a nanometer is? It is one thousand millionth of a meter, or you could perhaps visualise it as one millionth of a millimeter. So I hope you can see that this is a silly question.
1 million of 1 millimetres is a kilometre, but I am guessing that you mean a millionth of a millimetre by the way it's phrased. A millionth of a millimetre is a nanometre.
A micrometer, customarily called a micron.
A micron is a micrometer (one millionth of a meter, or one thousandth of a millimeter), so 0.3 micrometers = 300 nanometers.
