Conversion factors for making saltwater

I was on another fourm and noted that some people were confused with the cup/pint/quart/gallon measurements that we use in the US. Therefore, I did a breakdown with a conversion factor to use for liters/ml of water.A teaspoon is 5 ml. A tablespoon is 15 ml. One liquid ounce is 30 ml. A cup (8oz) is 240 ml, pint (16oz) is 480 ml, quart (32oz) is 960 ml, gallon (128oz) is 3840 ml. (ignore what the American bottling companies write on the labels, they are wrong. Chemistry conversions are not variable, bottling conversions are.) A tablespoon per 16 oz translates to 15ml per 480ml of dechlorinated water. (15/480 = 1/32)**This gives us a conversion factor of 1/32 (that is 1ml salt per 32 ml water.) To use that conversion factor you would divide the measurement in ml of liquid you are mixing into by 32 and use that many ml of salt. For instance: 2 liters is 2000 ml... 2000/32=62.5 ml of salt for 2 liters 62.5ml of salt divided by 15 ml per Tablespoon is 4.166666 Tablespoons for 2 liters....(Yes, I do realize that a liter is just a little more than a quart, and therefore most are probably just rounding the Tablespoons, but now you know the math involved )
