# Unit of Measurement

Change the unit of measurement by updating the **Unit** property. The default unit to draw a barcode is Pixel.

The following table lists the different available units of measurement for the **UnitOfMeasurement** enumeration. The dimension below represents a width/height of the barcode.

Unit of Measure | Dimensions |
---|---|

UnitOfMeasurement.Pixel |
This unit of measure uses the dimension as is. |

UnitOfMeasurement.Inch |
Multiplying the dimension with DPI will give the width in pixels. pixelWidth = dimension * dpi (Dots Per Inch) |

UnitOfMeasurement.Millimeter |
1 millimeter = 0.03937 Inches pixelWidth = (dimension * 0.03937f) * dpi (Dots Per Inch) |

UnitOfMeasurement.Mil |
1 mil = 0.001 Inches pixelWidth = (dimension * 0.001f) * dpi (Dots Per Inch) |

UnitOfMeasurement.Point |
1 point = 0.0138 Inches pixelWidth = (dimension * 0.0138f) * dpi (Dots Per Inch) |

The default unit of measurement used by DynamicBarcode Creator for .NET is pixels, as specified by the **UnitOfMeasurement.Pixel**.

DPI is a measure of dots per inch and determines a barcode's pixel resolution. For instance, one inch at 300 Dpi you need 300 pixels to draw. The following are some common measurement conversions.

- 1 Millimeter = 0.03037 Inch
- 1 Mil = 0.001 Inch
- 1 Point = 0.138 Inch

Note that pixels are independent of dpi and that pixels are the default unit of measurement. You can change unit of measurement property by setting the bar code's **Unit** property. The following example illustrates.

```
barcode.Unit = UnitOfMeasurement.Inch;
```

```
barcode.Unit = UnitOfMeasurement.Inch
```
