What is the difference between Atomic mass unit [u] and Dalton?

Both units represent the same fundamental mass standard defined as 1/12 of the mass of a carbon-12 atom, but Dalton is another name for the unified atomic mass unit with a very slight numeric difference in conversion.

Why convert Atomic mass unit [u] to Dalton if they are nearly the same?

They are used interchangeably in different scientific contexts; converting ensures consistency across chemical, biochemical, and physical measurements.
