1 mm = 1000 µm (millimeter → micrometer (micron))
1 mm = 1000 µm
1 millimeter equals 1000 micrometers. To convert millimeters to micrometers, multiply the millimeter value by 1000. For quick reference: 1 mm = 1000 µm, 5 mm = 5000 µm, 10 mm = 10000 µm, 100 mm = 100000 µm.
Micrometers = Millimeters × 1000Start with your value in millimeters.
Multiply the millimeter value by 1000. This is the exact conversion factor from millimeters to micrometers.
The product is your value in micrometers. For example, 5 mm × 1000 = 5000 µm.

A credit card is about 0.76 mm thick. Standard A4 paper is 0.1 mm thick. A pencil lead is around 2 mm in diameter. In micrometers, that gives you: 1 mm = 1000 µm, 10 mm = 10000 µm, 100 mm = 100000 µm.
The millimeter (mm) is a metric unit of length equal to one-thousandth of a meter. It is the working unit of engineering drawings, precision manufacturing, electronics, and most consumer-goods specifications outside the United States. A credit card is about 0.76 mm thick; the diameter of a pencil lead is around 2 mm.
The micrometer (µm), also called the micron, equals one-millionth of a meter. It is the working unit for semiconductor feature sizes, human hair and cell diameters, and precision-manufacturing tolerances.
