Summarize this article in one sentence.
The more your turkey weighs, the longer you’ll need to roast it for. You can find out how much your turkey weighs by checking the plastic wrapping that it came in.  8–12 pounds (3.6–5.4 kg): roast for 1.5-2 more hours. 12–14 pounds (5.4–6.4 kg): roast for 2-3 more hours. 14–20 pounds (6.4–9.1 kg): roast for 3-4 more hours. 20–24 pounds (9.1–10.9 kg): roast for 4-5 more hours. When you check on the turkey, check its temperature with the thermometer to make sure it’s going up. You can also brush on more melted butter or oil to give it more flavor. If the turkey looks like it’s burning or getting too crisp, cover the top with aluminum foil. Your turkey will be fully cooked and safe to eat at this temperature. Check the temperature with the thermometer at multiple depths in different places to make sure the whole turkey is cooked through. Check the center of the turkey with the thermometer since it will take the longest to cook. After 30 minutes, your turkey should be cool enough to carve and serve. Carve the turkey and serve it with stuffing, mashed potatoes, or your other favorite sides.

Summary:
Roast the turkey for 1.5-5 more hours depending on its weight. Check on the turkey every hour. Take the turkey out of the oven once it reaches 165 °F (74 °C). Let the turkey cool for 30 minutes before serving.
