Whether rounding only on conversion would be confusing depends on the background of the reader. The casual reader will be confused by many significant digits (or apparently significant digits) no matter what we do. The reader with a rigorous quantitative background such as scientists and engineers will expect the original value would have been entered correctly, and will recognize the inherent data loss involved in conversion. I think such a reader would expect us to preserve precision when some cases will require such preservation to properly present the original value (even if badly entered values will look bad). Such a user will expect us to round on conversion because that is customary among people with a strong quantitative background. Preserving the input when there is no conversion also helps to bring badly-entered original values to the attention of editors who can then fix them.
