How many minutes per pound do you cook a 14.7 turkey at 325 degrees?

There is no defined relationship between weight and time when roasting at different temperatures according to the USDA.

The safe minimum internal temperature for poultry and stuffing to avoid salmonella poisoning is 165°F. For recipes containing vegetables, the internal temperature needs to reach at least 165°F for 15 seconds. Use a food thermometer to ensure internal temperature is met or exceeded prior to consumption.
