There are 5 grams of water in a teaspoon. 1,200 mg of fish oil is roughly 1/4 teaspoon
1 teaspoon is 5,000 mg .
ANSWER In 1 US teaspoon there are 4.93 grams of vinegar. Multiply this result on 1000 and receive weight in mg. 1 US teaspoon = 4930 mg of vinegar
1/4 teaspoon salt = 600 mg sodium 1/2 teaspoon salt = 1,200 mg sodium 3/4 teaspoon salt = 1,800 mg sodium 1 teaspoon salt = 2,300 mg sodium
1,000 mg is 1 gm. 1 tsp is 5gm. -So 570 mg is about 1/9 of a teaspoon
No, a teaspoon is 5,000 mg of water. -So 600 is about 1/8 of a teaspoon
1/4 teaspoon salt = 600 mg sodium 1/2 teaspoon salt = 1,200 mg sodium 3/4 teaspoon salt = 1,800 mg sodium 1 teaspoon salt = 2,300 mg sodium 1 teaspoon baking soda = 1,000 mg sodium
