Sorry to say, but with my civil engineering education, when you get into more complex units and relationships, metric conversions quickly become just as messy as US units.
Very true. Same experience for me in my CE degree. NEITHER one is simple, both are convoluted to some degree. Both start with a basic idea and then grow from there:
1 pound of water = 1 pint of water
1 ml of water = 1 g of water
metric ads another equivalence 1cc = 1ml
But none of that makes it simple, really. Relatability makes things simple.
People average between 5' and 6' tall, and being able to break that down into feet and inches makes it relatable. Saying people range from 1.525 to 1.825 meters and having that mean something is a much harder sell...

its about 2.25lbs/kg
No, it's about 2.2lbs/kg. You are arguing one of the most common conversions we learn? Why?

When even though we have 75 and 76, seriuosly, could your really tell. Turning the thermostat, it's either 70 or 75 or 80 to me.
That's because you are impatient. You can easily feel the difference between 75 and 76 in your home if you allow the system to actually bring your house to the new temp. I make one F changes all the time on my digital thermostat, and it makes a difference.

open any math/chemistry/physics textbooks, and they are all in the metric system...
You might want to open on first to see the proper conversion factors, then read further to see they do problems in both in physics text books. In chemistry, usually not, and in math? Math is not about using metric or imperial units. Examples might have either/or, but they need not have units at all!
