Anyone who thought changing the measurement system wasn't going to be met with resistance was delusional. People hate change. Sometimes, change is better. As someone who went through it in Canada, there was a lot of disgruntlement from the previous generation, but the rest of us just moved on (mostly), and being able to just use decimals everywhere instead of base 2 fractions here, decimals there, multiples of 12 over there was absolutely refreshing. Now my kids barely even use imperial and just shake their heads when the oldsters talk about it.
And I'd still rather measure people's weight in pounds than in stone like a monster.
