Millimeters to Micrometers

Convert millimeters (mm) to micrometers (μm) with formulas, examples, and conversion tables.

Millimeters (mm)

Micrometers (μm)

μm

1 mm = 1000 μm

Full precision:1000 μm

Feet + Inches:1.55 in

Step-by-Step Solution

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

1 millimeter = 1000 micrometers

Since each millimeter contains 1000 micrometers, we multiply our value by this factor:

1 × 1000 = 1000 micrometers

So 1 millimeters = 1000 micrometers.

✓Quick check: 1000 ÷ 1000 = 1 millimeters

How to Convert Millimeters to Micrometers

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

Micrometers = Millimeters × 1000

1 millimeter = 1000 micrometers

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

Example 1: 1 mm = 1000 μm
1 × 1000 = 1000

Example 2: 5 mm = 5000 μm
5 × 1000 = 5000

Example 3: 10 mm = 10000 μm
10 × 1000 = 10000
