Table salt is a compound of the two chemical elements sodium and chlorine. If you want to keep track of the amount of sodium you eat every day, you’ll need a way to measure it. Sodium in food is measured in milligrams (mg), a metric unit that measures mass.
“Milli” means “one thousandth,” or 1/1,000, so milligram means 1/1,000 of a gram. A gram (g) is about the weight of a small paper clip. If you broke that paperclip into 1,000 pieces, each piece would weigh 1 mg. In math terms this means:
1 mg = 1/1,000 gram (1 mg is 1/1,000 of a gram.)
Which is the same thing as:
1,000 mg = 1 g (There are 1,000 mg in 1 gram.)
To convert grams to milligrams: multiply the number of grams by 1000.
To convert milligrams to grams: divide the number of milligrams by 1000.
Drag and drop each milligram (mg) measurement to the matching gram (g) measurement.
