Jayseem, I've never seen a label on anything indicate measures like that. Are you sure you're looking at the Manufacturer's Suggested Serving Size? It will be right at the top of the Nutrition Panel. On US foods, it usually gives a serving measured in cups or measuring spoonfuls (or in the case of asparagus spears, a certain number of spears) followed by a weight in grams enclosed in parentheses.

Can you post the brand name of the asparagus? Then I can try to find it online.

Perhaps this explanation and diagram from the USDA will help you:
