noun, f. | -ας
86.4 · Weight · Pound, Talent [Specific Units of Weight]
pound, pint a Roman pound, weighing about twelve ounces or about 325 grams In speaking of perfume in JHN 12:3 it may be far better to indicate quantity rather than weight, and therefore one may translate ‘then Mary took a pint of perfume.’ In translating λίτρα in the NT, one need not identify the pound as being ‘a Roman pound.’ It is better to employ a common term for pound (normally weighing sixteen ounces) or to provide a rounded-off equivalent of the amount in metric units, for example, three hundred grams or one-half liter.
