A pennyweight (abbreviated dwt) is a unit of mass that is equal to 24 grains, 1â20 of a troy ounce, 1â240 of a troy pound, approximately 0.054857 avoirdupois ounce and exactly 1.55517384 grams.
1 pound= 453.59237 grams. Which is a number with a ridiculous number of decimals. Those last 3 or 4 are uncalled for in most situations and if the 1 pound is only accurate to one digit the answer should also only be accurate to one digit 500g (half a kilogram) is usually close enough.
