- Read the total weight in grams.
- Divide it by 453.59237.

Five hundred grams is often informally called about a pound, but it is actually a little heavier: approximately 1.10231 lb. For quick mental estimation, 454 g is very close to 1 lb.
When the source label shows only whole grams, a long pound result does not imply the original measurement was equally precise.
