It seems that  linear acceleration units are mm/s.

Not quite... There was a bit more to it than that. The original OpenCR code doesn't convert from the raw values. That was fixed in [this PR](https://github.com/ROBOTIS-GIT/OpenCR/pull/45).

That fix and others are present on the [features-from-openrobotics](https://github.com/ROBOTIS-GIT/OpenCR/tree/features-from-openrobotics) branch on the OpenCR repo. If you checkout those changes and flash the image, then your IMU values will be correct.
