How do I change the Report Designer Ruler unit from Inches to centimetres?

Question

A simple (I hope) question, I'm using Visual Studio, I create a new report in SQL Server Business Intelligence Development Studio. In layout view the ruler is in inches, I would like to change it to centimetres.

Update 1

Changing the regional settings worked.

Is it not possible to do this without changing the regional settings? I would have hoped this would be a setting within Visual Studio.

Answer 1

Try the Windows Regional Settings?

Answer 2

Change Regional Settings from English (United States) to English (Australia)

ie through Start > Control Panel > Regional and Language Settings.
