Here's a question about observational variables. Many of our sensors measure variables that are in the standard names list, but the data is not yet converted to science units, for example temperature or oxygen concentration.

These measurements are typically represented by a unit like 'volts' (or even 'counts') -- definitely not directly convertible to the canonical units! Is there a standard technique that would let me convert any existing standard name to a 'raw units' standard name?

If not, to start the conversation perhaps I can suggest one of the following to indicate such metrics?
 suffix: _in_engineering_units
 suffix: _in_raw_units
 prefix: raw_measure_of_

This capabilitiy will be important for finding data that potentially can be converted to the desired values, but has not yet been converted. (Some of our collected parameters are not the primary purpose of the experiment, and they remain in raw units unless someone needs them converted.)
