The question "how many grams is 1" seems incomplete, but based on common context, here are the most likely relevant conversions:
- 1 pound (lb) is equal to 453.592 grams (often rounded to 454 grams).
- 1 ounce (oz) is equal to 28.34952 grams (about 28 grams).
If you meant 1 of a different unit, please specify, so I can provide the exact conversion.
