Frequently Asked Questions

How do I convert mg to grams?

Divide by 1,000, since "milli" means one thousandth. For example, 500 mg ÷ 1,000 = 0.5 g.

How many grams is a 500 mg tablet?

0.5 g, half a gram. The figure on a medicine label is the amount of the active ingredient, not the weight of the whole tablet.

How many mg of sodium is too much?

US dietary guidelines advise less than 2,300 mg of sodium a day, which is 2.3 g. Labels give sodium in mg because the amounts are small.

What is the difference between mg and mcg?

A microgram (mcg or µg) is a thousandth of a milligram: 1 mg = 1,000 mcg. Vitamins such as B12 and D are dosed in micrograms, so check the unit before comparing labels.
