Not listing alternate units second, not converted on screen, not called “freedom units” and not hiding behind the excuse of “most our audience is in the US”

The difference between a meter and yard is less than that of a measured vs “eyeballed” yard and everybody knows what 0 C and 100 C are so the learning curve is also massively (by at least 50 kg) exaggerated
You are talking about inter-unit conversions. This is not what people complain about with imperial - they complain about intra-unit conversions. And rightfully so: why use a unit system that adds extra complexity on top of the existing complexity? Why use a system that adds unnecessary complexity on top of necessary complexity?
But why use a system that is harder for rare cases, than one that’s not harder for any cases?
