**Definition**:

```csharp
enum ZemaxSystemUnits {
  Millimeters = 0,
  Centimeters = 1,
  Inches = 2,
  Meters = 3
}

```

Usage (see [Example 11](../apiexamples/example_11.md) for a full sample)

C#

```csharp
            // Set system lens units to inches, scale all values with Scale Lens tool
            // For demonstration only. This file is new, so it has default units mm.

            ScaleLens = TheSystem.Tools.OpenScale();
            // Apply Tool Settings
            ScaleLens.ScaleByUnits = true;
            ScaleLens.ScaleToUnit = ScaleToUnits.Inches;
            ScaleLens.RunAndWaitForCompletion();
            ScaleLens.Close();

```

C++

```csharp

    // For demonstration only. This file is new, so it has default units mm.
    ZemaxSystemUnits unit = TheSystemData->Units->LensUnits;

    ScaleLens->ScaleToUnit = ScaleToUnits_Inches;
    ISystemToolPtr baseTool = ScaleLens;
    baseTool->RunAndWaitForCompletion();
    baseTool->Close();

```

Matlab

```csharp
    % Set system lens units to inches, scale all values with Scale Lens tool
    unit = TheSystemData.Units.LensUnits;  % For demonstration only. This file is new, so it has default units mm.
    ScaleLens = TheSystem.Tools.OpenScale();  % Open Scale Lens tool

    ScaleLens.ScaleByUnits = true;
    ScaleLens.ScaleToUnit = ZOSAPI.Tools.General.ScaleToUnits.Inches;
    ScaleLens.RunAndWaitForCompletion();
    ScaleLens.Close();

```

Python

```csharp
    # Set system lens units to inches, scale all values with Scale Lens tool
    unit = TheSystemData.Units.LensUnits  # For demonstration only. This file is new, so it has default units mm.
    ScaleLens = TheSystem.Tools.OpenScale()  # Open Scale Lens tool
    # Apply Tool Settings
    ScaleLens.ScaleByUnits = True
    ScaleLens.ScaleToUnit = 2  # 0=millimeters; 1=centimeters; 2=inches; 3=meters
