I'm confused about how the existing capability does not fully meet your needs. You TELL UNITS what you need and it won't give you any units on the output. This avoids the possibility of being bitten by assumptions later on, and no post processing is required. > > I was just hoping there was a way to say > units --give-me-just-how-many-meters(feet, etc.)-please This feature already exists. It's unit conversion. You just need to give the "I want" factor in your invocation, as I have noted in my earlier messages: units --terse mile meters The output is a bare number. Or, you know units --terse mile inch would display a bare number giving the mile in inches.
