A recipe that says "1 tablespoon of kosher salt" can mean 8 grams or 14 grams. That is why this calculator works in weight.

The USDA recipes

  • Wet brine for poultry: 3 tablespoons of table salt per quart of water (¾ cup per gallon). Submerge the poultry, cover, and refrigerate at least overnight. Up to 2 days. Discard the brine.
  • Dry brine: 1 tablespoon of kosher salt for every 5 pounds of poultry, rubbed on and refrigerated up to 2 days.

How it is calculated

  • Wet brine salt (g) = water weight (g) × salt percent ÷ 100. Water: 1 ml = 1 g.
  • USDA wet brine = 3 tbsp table salt per quart = 3 × 18.25 g ÷ 946 g = 5.8%.
  • USDA dry brine = 1 tbsp kosher salt per 5 pounds of poultry. Grams depend on the brand.

Worked example

2 liters of water at 5.8%: 116 g of salt. A 12 pound turkey dry brined by the USDA rate: 2.4 tablespoons of kosher salt, which is 20 g of Diamond Crystal or 35 g of Morton.

Questions

How much salt do I put in a brine?

USDA gives 3 tablespoons of table salt per quart of water, which is ¾ cup per gallon. By weight that is about 5.8% of the water's weight.

Why measure salt by weight?

Salts differ a lot in volume. A cup of Diamond Crystal kosher salt weighs 134 g and a cup of Morton kosher salt weighs 230 g. The same tablespoon makes a very different brine.

How long should I brine?

USDA says refrigerate at least overnight for best results. Poultry may be left in the refrigerator up to 2 days after it is thawed or bought fresh.

Can I reuse the brine?

No. Remove the poultry, then discard the brine after use.

What is a dry brine?

Rub salt on the surface of the poultry and refrigerate it, up to 2 days. USDA gives 1 tablespoon of kosher salt for every 5 pounds.

Does brine have to stay cold?

Yes. Keep it covered in the refrigerator the whole time. Never brine at room temperature.
