Your family is coming for dinner.
You want to cook a turkey.
You need to read a chart to know how long to cook the turkey.
You have a 13-pound turkey that is not stuffed.
Put a finger from your left hand on 12 to 14 pounds in the Weight column.
Put a finger from your right hand on the Unstuffed Turkey column.
Move your left hand to the right and move your right hand down.
When your hands met you see that you need to cook your turkey for 3 to 3¾ hours.
