Plan on 1 to 1.5 pounds of whole turkey per person for a bone-in bird. If you want generous leftovers, use 1.5 to 2 pounds per person. For a boneless breast, 0.5 to 0.75 pounds per person is enough. A 15-pound whole turkey comfortably feeds 10 to 12 guests. Use the Thanksgiving Turkey Calculator for an exact recommendation based on your guest count and leftover goals.

Plan on 0.5 pounds of cooked brisket per person, or 1 pound of raw brisket per person since brisket loses roughly 40 to 50 percent of its weight during smoking. For a hungry crowd where brisket is the star, use 0.75 pounds cooked per person. The Brisket Per Person Calculator automatically accounts for cook loss so you know exactly how much raw brisket to buy.

A standard 750ml bottle of wine holds 5 glasses at a 5-ounce pour. For a 2-hour party, plan on 1 glass per person per hour, or 40 glasses total for 20 guests over 2 hours. That is 8 bottles. For a dinner party where wine flows more freely, use 10 to 12 bottles. The Wine Bottles Per Person Calculator adjusts for party duration and drinking pace.

Divide the number of servings you need by the original yield to get the scaling factor, then multiply every ingredient by that factor. A recipe for 4 scaled to 12 uses a factor of 3 (multiply every ingredient by 3). For baking, leavening agents like baking powder and yeast do not always scale linearly above a 2x factor. The Recipe Scaler Calculator handles this automatically and flags ingredients that need special attention.

The Specialty Coffee Association of America (SCAA) Golden Ratio is 1 to 2 tablespoons of ground coffee per 6 ounces of water. In grams, that is 10 grams of coffee per 180ml of water. For a standard 12-cup drip maker, use 10 to 12 tablespoons (about 60 to 72 grams) for 60 to 72 ounces of water. The Coffee to Water Ratio Calculator covers drip, pour-over, French press, AeroPress, and cold brew methods.

Grams per cup vary significantly by ingredient because different materials pack differently. All-purpose flour is about 120 to 125 grams per cup, granulated sugar is 200 grams per cup, butter is 227 grams per cup (one standard US stick), and rolled oats are about 90 grams per cup. Volume measurements are unreliable for dry ingredients since packing affects weight. The Cups to Grams Converter covers 50 plus common baking and cooking ingredients with precision values.
