How much beef to make 30 hamburgers?

You'll need about 5-6 pounds of ground beef to make 30 hamburgers.

Here's why:

* Standard Patty Size: A typical hamburger patty is about 4 ounces.

* Total Weight: 30 patties x 4 ounces/patty = 120 ounces of beef.

* Conversion to Pounds: 120 ounces / 16 ounces/pound = 7.5 pounds of beef.

* Allow for Shrinkage: Ground beef shrinks slightly during cooking. It's a good idea to add a little extra beef to account for this.

Therefore, 5-6 pounds of ground beef is a safe bet for 30 hamburgers.
