Centimeter isn't a metric unit :-P SI goes in thousands km, m, mm

for the range 10^-3 to 10^3 SI units are defined for every integer power of 10. powers of 1000 apply outside that range

This does not say otherwise than what I said, but exactly confirms it.

Check the lists of SI prefixes. You'll find centi listed along with deci, deca and hecto, none of which are powers of 1000.

BTW, NIST is the official U.S. standards body. The other link is for a German source.

Just wait a dekasecond, there, I've got hectoexamples where usage differs and those non power of thee units are not used.

How can I have metric units in the print window?

I am using libreoffice-3.5.4.7-4.1.x86_64 on one machine and see mm not inches (on another machine with libreoffice-3.4.5.5-4.5.1.x86_64 I also see mm). Have you tried to update to 3.5.4.7, maybe that was just a regression.

Centimeter is sure, a metric unit. I am not sure about SI unit, but no one said that cm was an SI unit. Why do you mix two system?

Both the links I provided list the base units, such as metre and then a list of prefixes such as centi. Both links are for "SI", so centimetre definitely is part of the SI system. If you disagree, perhaps you should let the NIST know they're wrong.

You are right, I did not say you're not. Since I was not sure about SI units (whether cm belongs to them, and accordingly to the table you linked, it does), I only stated that independently of SI system cm is a metric unit. In my original post there was no mention of SI units but was of metric units. Second, even if cm was not a SI unit, it'd still be a metric unit, because these are two different systems. I only tried to make this clear. What you are saying only confirms that SI adopted the metric system for length.

In my desktop the units are set to metric, that is centimeter,

I think any scientist would argue about centimeters not being a metric unit. One centimeter is ten millimeters.
