1 μm = 0.001 mm
Full precision:0.001 mm
Step-by-Step Solution

To convert 1 micrometers to millimeters, we divide by 1000 because one millimeter equals exactly 1000 micrometers.

1 millimeter = 1000 micrometers

Since there are 1000 micrometers in every millimeter, we divide our value by this factor:

1 ÷ 1000 = 0.001 millimeters

So 1 micrometers = 0.001 millimeters.

✓Quick check: 0.001 × 1000 = 1 micrometers

How to Convert Micrometers to Millimeters

To convert micrometers to millimeters, divide the value by 1000.

The Formula

Millimeters = Micrometers ÷ 1000

Key Fact

1 millimeter = 1000 micrometers

Tip: To convert millimeters back to micrometers, multiply by 1000.

Example Conversions

Example 1: 1 μm = 0.001 mm
1 ÷ 1000 = 0.001
Example 2: 5 μm = 0.005 mm
5 ÷ 1000 = 0.005
Example 3: 10 μm = 0.01 mm
10 ÷ 1000 = 0.01
