Question details
The user wants to change the measurement system in PowerPoint for Mac from inches to centimeters (metric) without changing the macOS system language from English.

- Product
- PowerPoint for Mac
- Device & OS
- macOS
- Scenario
- Adjusting the ruler and shape measurement units for precise slide editing and layout formatting.
- Observed behavior
- PowerPoint continues displaying measurements in inches because it defaults to the English language standards, even when the macOS region is set to Germany.
Ensure you save your work and completely close Microsoft PowerPoint for Mac before making system-level changes, as the application needs to restart to detect new measurement settings.
Change macOS System Settings to Metric
Since PowerPoint for Mac does not have an independent unit setting, you must force macOS to use the Metric system globally.
PowerPoint for Mac relies entirely on your global macOS settings for its measurement units. Unlike Microsoft Word for Mac, you cannot change the units directly inside the PowerPoint Preferences menu. By manually setting your macOS Measurement System to Metric, PowerPoint will use centimeters without requiring you to change your system display language to German or another language.
Click on the Apple menu logo at the top-left corner of your Mac screen and select 'System Settings' (or 'System Preferences' on older macOS versions).
In the left sidebar, click on 'General', then select 'Language & Region' from the options on the right.
Scroll down to find the 'Measurement System' dropdown menu. Click it and change the selection from 'US' or 'UK' to 'Metric'.
Close the System Settings window. Open PowerPoint for Mac to verify that rulers and object dimensions are now displayed in centimeters.

Frequently Asked Questions
Why does PowerPoint for Mac use inches when my region is set to Germany?
PowerPoint for Mac often defaults to the measurement system associated with your primary system language (such as US English). It ignores the regional setting for measurements unless you explicitly manually change the Measurement System to 'Metric' in macOS settings.
Can I change measurement units directly inside PowerPoint for Mac settings?
No. Unlike Microsoft Word for Mac, which has an internal setting for measurements under Preferences, PowerPoint relies completely on your global macOS system-wide measurement settings.
What should I do if PowerPoint still shows inches after changing to Metric?
Try fully quitting the application by pressing Cmd + Q, then reopen it. If the issue persists, restart your Mac to ensure the system-wide metric changes are properly registered by all installed software.
Will changing the macOS measurement system affect my English language interface?
No. Adjusting the Measurement System to Metric only alters the units used for length and weight (like centimeters or kilograms). Your menus, dialogues, and spell check will remain in English.
