Question details
The user wants to know how to change the measurement units from inches to millimeters when viewing a document via the Adobe Acrobat extension.

- Product
- Adobe Acrobat Chrome Extension
- Device & OS
- ChromeOS
- Scenario
- Viewing, evaluating, or measuring PDF documents using the browser extension on a Chromebook.
- Observed behavior
- The extension displays page measurements exclusively in inches and lacks the preferences menu found in the desktop app to switch units to millimeters.
Ensure your Google Chrome browser and the Adobe Acrobat extension are updated to the latest versions, as developers frequently release updates that may modify available settings.
Understand ChromeOS Extension Limitations
The Adobe Acrobat Chrome extension is a simplified version of the software and does not support advanced desktop preferences like unit conversion.
ChromeOS does not natively support the full Adobe Acrobat desktop application. While the Acrobat Chrome extension provides essential PDF viewing and markup features, it strips away many advanced settings to remain lightweight.
Open a PDF using the Acrobat extension in your Chrome browser and click the settings or menu icon in the toolbar to view the available viewing options.
Note that the option to switch from inches to millimeters is currently omitted. Measurements will remain in inches by default within the extension interface.

Use Alternative PDF Workarounds
Since the extension cannot change units, utilize workarounds or alternative platforms to measure your PDF documents in millimeters.
Effortlessly Manage and Edit PDFs with WPS Office
If you are struggling with the limited PDF features on browser extensions, consider switching to WPS Office. It provides a robust, fully featured suite for documents, spreadsheets, presentations, and comprehensive PDF management.

Frequently Asked Questions
Can I install the full Adobe Acrobat desktop app on ChromeOS?
No, ChromeOS does not natively support the full desktop version of Adobe Acrobat. Chromebook users must rely on the Adobe Acrobat Chrome extension or the Android app version available via the Google Play Store.
Will Adobe add the measurement units feature to the Chrome extension?
Adobe continuously updates its extensions, but there is currently no official roadmap indicating when or if advanced preferences, such as unit measurement changes, will be implemented in the Chrome extension.

On a Windows or Mac computer, open Acrobat, go to 'Edit' > 'Preferences' (or 'Acrobat' > 'Preferences' on Mac), select 'Units & Guides' from the left sidebar, and change the 'Page & Ruler Units' dropdown to Millimeters.
