How to Fix Microsoft 365 Using Imperial Units Instead of Metric on Mac
Question details
The user wants Microsoft 365, specifically PowerPoint for Mac, to display measurements in the metric system (centimeters or millimeters) instead of imperial units.
- Product
- Microsoft 365 / PowerPoint for Mac
- Device & OS
- macOS
- Scenario
- Configuring regional measurement units for precise document editing, formatting, and shape sizing.
- Observed behavior
- Microsoft 365 continues to display imperial measurements in its interfaces even though the macOS system settings are already configured to use the metric system.
Ensure you have saved all your open documents, as you will need to completely quit and restart your Office applications or restart your Mac to apply system-wide regional changes.
Verify macOS System Settings and Restart Applications
Ensure the macOS system settings are correctly forcing the metric system and completely restart Office to apply the new configurations.
Microsoft Office for Mac does not have its own internal setting for measurement units; it relies entirely on your macOS Language & Region preferences. Sometimes, Office apps fail to sync with these settings until a complete restart is performed.
Click the Apple menu in the top-left corner of your Mac screen and select 'System Settings'.
Go to the 'General' tab in the left sidebar and then click on 'Language & Region'.
Find the 'Measurement system' option and ensure it is explicitly set to 'Metric' rather than 'US' or 'UK'.
Completely quit Microsoft PowerPoint and any other open Office apps by pressing Cmd + Q. Reopen them to check the units. If the issue persists, restart your Mac entirely.
Enter Metric Units Explicitly in PowerPoint Fields
If the system fails to update the display units, you can manually type metric units into the measurement boxes as a quick workaround.
Report the Sync Bug to Microsoft
If restarting does not resolve the metric unit bug, report the persistent issue directly to Microsoft so it can be patched in future updates.
Switch to WPS Office for a Flawless Mac Experience
If Microsoft 365 continues to ignore your Mac's metric settings, consider switching to WPS Office. It perfectly adapts to your system preferences, providing a seamless, lightweight, and free Office alternative with full compatibility for your existing PowerPoint, Word, and Excel files.
- 1. Download for Mac: Visit the official WPS Office website and download the free installation package for macOS.
- 2. Install WPS Office: Open the downloaded file and follow the standard on-screen prompts to install the application on your Mac.
- 3. Open Your Presentations: Launch WPS Presentation and seamlessly open your existing .pptx files to edit them with reliable metric measurements.
Frequently Asked Questions
Why is PowerPoint for Mac stuck on inches instead of centimeters?
PowerPoint for Mac relies entirely on your macOS system settings for measurement units. However, due to software syncing bugs or pending updates, it sometimes fails to recognize the 'Metric' setting in Language & Region, causing it to default back to imperial units (inches).
Can I change the measurement units directly within PowerPoint for Mac settings?
No. Unlike the Windows version of PowerPoint, which allows you to change units in the Advanced Options menu, PowerPoint for Mac does not have an internal setting for measurement units. It strictly follows the macOS System Settings.
How do I temporarily use centimeters if my system is stuck on inches?
You can manually type the unit abbreviation directly into the size input boxes. For example, typing '5 cm' or '50 mm' into the height or width box will force PowerPoint to apply that exact metric measurement, automatically converting it in the background.
