'Weight' in the Bible

Availing herself of the opportunity, Mary took a pound weight of pure spikenard, very costly, and poured it over His feet, and wiped His feet with her hair, so that the house was filled with the fragrance of the perfume.

And there came also Nicodemus, which at the first came to Jesus by night, and brought a mixture of myrrh and aloes, about an hundred pound weight.
