Changing the measurement units in PowerPoint is completely different from Word, Excel... and they often frustrate many users. PowerPoint currently uses the computer's default units, making it impossible to replace them within the software.

1. How to Activate Ruler in PowerPoint
By default, the ruler in PowerPoint remains inactive, requiring users to manually enable it for use. Here's how to activate the ruler:
Step 1: Proceed to select the View tab.
Step 2: Mark the Ruler option in the Show section.

Step 3: At this point, PowerPoint will display the Ruler system horizontally and vertically for your use.
With this ruler, you can measure any distances within the Slide and adjust them to align, distribute, or create offsets.

2. How to Change Measurement Units in PowerPoint
By default, PowerPoint uses the measurement system of Windows computers, which is predominantly set to U.S. measurements. This means that the ruler in PowerPoint displays measurements in inches rather than centimeters or millimeters. In Vietnam, less than 1% of the population uses inches, making it unnecessary and impractical for most users. You'll need to change it to centimeters or millimeters to fully utilize PowerPoint's ruler feature.
Changing the measurement units on your computer won't affect other software programs and might even prompt them to switch to using the metric system as their primary measuring tool instead of the U.S. system.
Step 1: Open the Start Menu and type Control Panel to access it.

Step 2: Then, select the Clock and Region option to set time, coordinates, location, etc.

Step 3: Next, choose the Region tab to view additional information related to the current location.

Step 4: When the Region window appears, select the Formats (1) tab and choose Additional Settings… (2) to view extended settings.

Step 5: In the Customize Format window, locate the Measurement System and change it to Metric (metric measurement system).

Step 6: Now, restart PowerPoint and the Ruler bar has been changed to Centimeters - the commonly used unit in Vietnam.
So there you have it, you've successfully converted the measurement unit from Inch to Centimeter in PowerPoint, swiftly and accurately.

In this article, Software Tips has guided you on how to switch the measurement unit in PowerPoint from Inch to Centimeter. Have a great day, everyone!
