How long to cook 4.23 lb round roast?

I need more information to give you an accurate cooking time for your 4.23 lb round roast! Here's what I need to know:

* What kind of round roast is it? (Top round, bottom round, eye of round, etc.) Different cuts have different fat content and cook differently.

* What cooking method are you using? (Oven, slow cooker, grill, etc.)

* What internal temperature are you aiming for? (Medium-rare, medium, well-done?)

* What is the size of your roast? (4.23 lb is the total weight, but I need to know the approximate dimensions for a more accurate cook time.)

Once you provide me with this information, I can give you a more precise cooking time estimate. 😊
