One kiloDalton (kD) is equal to approximately the weight of one thousand hydrogen atoms, and is equivalent to 1.66 x 10-21 grams. We use this unit to express the size of proteins.

I say approximately the weight of one thousand hydrogen atoms. In fact, to be more precise it's one-sixteenth of the weight of one thousand oxygen-16 atoms.

The Dalton was named after John Dalton, a pioneer in the development of an atomic theory of chemistry.
