## How to perform key conversions involving length measurements

The formulas for conversion are represented below:

### Millimeters to Micrometers Formula

µm = mm * 1000

Example: 30 Millimeters in Micrometers:

µm = mm * 1000

µm = 30 * 1000

µm = 30000

### Micrometers to Millimeters Formula

mm = µm / 1000

Example: 1.5 Micrometers in Millimeters:

mm = µm / 1000

mm = 1.5 / 1000

mm = 0.0015

## Frequently asked questions involving length and distance

### 100 Millimeters are equal to how many Micrometers

Considering that 1 Millimeter is equivalent to 1000 Micrometers, you can use a rule of three to obtain that 100 Millimeters equals 100000 Micrometers.

1 mm - 1000 µm

100 mm - x

Apply the rule of three and get:

x mm = 1000 * 100 µmmm

x = 100000 µm

### 100 Micrometers is equal to how many Millimeters?

If every 1000 Micrometers we have 1 Millimeter, just divide the number of Micrometers (100) by 1000, so you will obtain that 100 µm equals 0.1 mm. Observe the calculation below:

mm = µm / 1000

mm = 100 / 1000

mm = 0.1
