Well one way or another it's not a linear function, so calling it a non-linear conversion is technically not incorrect.
That said I completely agree that it makes way more sense to just call it a linear conversion and to pick an example that's truly nonlinear. Not that there are that many non-linear units, but something like decibel or beaufort might work.
- kazinator 6y agoInsistence that "linear function" is defined one way is not supported by facts: https://en.wikipedia.org/wiki/Linear_function https://en.wikipedia.org/wiki/Linear_function A "linear function" refers to a "linear map" only in certain contexts. The word "affine" can be used for a mapping that fails to meet the definition of a linear map operator due to offsets. That is much better than "nonlinear".
