How to used different Catalog while using US metric datasets seeds

Hi,

I am using U.S Metric building datasets seed, but still the material standard section such as concrete column are still in Imperial.

Is there a way to use different catalog such as UK while using U.S Metric building datasets seeds.

or how to change the standard section such as concrete column into metric size, I thought if I will used U.S. Metric building datasets seed all are in Metric.

Thanks in advanced
