Quantum Mechanics teaches us that a "truth" is only true relative to the device used to measure it and its position in space time. If meaning is subjective then so is everything we apply meaning to, including our units of measure.
UoM do have a subjective aspect, as the "what they mean personally to an individual", but when they are defined as a physical relationship they have a fixed relation that binds them to objective mathematical computation.
Likewise, meanings in general can be subjective to a person or culture; but (and this is "out of the box" to my conjecture) there is actual objective meanings that exist as real world probabilities. Nobody bulks at the term "object meaning" but give it metaphorical substance, as the sum of personal meanings. I am saying that nature activates information objects and they are objective in their origins and outcomes. In this way, LOVE can be an actual substance. (see Ian Thompson) DNA/RNA,Ribosome systems that express themselves as extended growth and maturity of organisms and would be actual and substantial information objects. Yet also be physical objects in any moment in time.
Keeping the UoM of physical environments as one kind; and UoM of mental experience as another, sorts a lot of this out!
