When using canned black beans, it’s essential to consider the net weight, which is the weight of the beans after draining and rinsing. The net weight of a 19 oz can of black beans is typically around 15 oz.
Converting Net Weight to Cups
Using the same conversion rate as before, we can calculate the number of cups in a 15 oz can:
1 cup of cooked black beans = 172 grams
1 ounce = 28.35 grams
15 oz can = 15 x 28.35 grams = 425.25 grams
Now, let’s convert the net weight to cups:
425.25 grams ÷ 172 grams per cup = approximately 2.47 cups
Conclusion
In conclusion, a 19 oz can of black beans contains approximately 3.13 cups of cooked black beans. However, after draining and rinsing, the net weight is around 15 oz, which is equivalent to approximately 2.47 cups.
