URIs / Ontology for Physical Units and Quantities

Say I am trying to share a tabular dataset. [1] There's metadata for
the Dataset, and there's metadata for the particular columns (which
applies to the particular data items).

For example:

t   volume (liters)
1  1
2  0.7
3  0.5
4  0.3
5  0.1

# Is there (a good) way to specify these units and quantities (in
addition to XSD datatypes)?

>From http://lov.okfn.org, I found:

*  QUDT (quantity:Time, quantity:Liter?)
*  MUO (muo:UnitOfMeasurement, muo:Prefix)

# How could I specify this type of columnar metadata with CSV?

* This may be a question for CSV on the Web Working Group Chapter?

# How in scope for schema.org would specifying a units ontology (e.g.
QUDT, because it loads faster) be?
