For me "measurement" implies known precision, and some straight-forwardness, simplicity and clear repeatability.
Estimation is on the other hand uses measurements as input and has no clear cut path forward. (you must assume some model)
"Chemistry is just applied physics" ("measurement is just estimating via proxy") might be technically correct, but distinction is still very real and usefull.
