The line at which you draw "Shared context" is also rather amusing. All of our 'objective measurements' are a shared context.
The difference being, obviously, that objective metrics-- celsius, centimetres, half-life, miles-per-hour, what-have-you-- are demonstrable to a near-exact degree. Once you demonstrate the system of measurement, you can then demonstrate where objects or substances exist on that scale.
Reference to an objective metric is-- blatantly-- not the same as merely understanding shared context.

However, because they're shared by the majority of people around you, you presume they are universal truths self evident in the object - which is wrong.
What? No, I don't. You've failed to understand again. The metric may not be shared by everybody, but it can be
demonstrated to those who do not share it. That's the entire value of those metrics, and why they were devised.
This really is some school-grade stuff.
