Again, you tell me. Units have no meaning without the context of what you're modeling. I can model the average temperature of your pieces of metal as (20C+15C)

I can model the average temperature of your pieces of metal as (20C+15C)/2=17.5C.
- ttoinou 3y agoUnits have no meaning without the context of what you're modeling. I fully agree with that statement ! But some addition of units are widely accepted because their associated model is almost universal on earth, let's say adding mass (kg) of two different objects
- sheepshear 3y agoYes, that's why we're having this conversation. It's so common that some people reasonably infer a stronger connection between units and physics.
