How to convert milliliters to milligrams
Weight and volume are linked by density. Water weighs 1 gram per millilitre, so for water mg = mL × 1,000 (water). For other substances, pick one above.
mg = mL × 1,000 (water)
2 mL of water = 2,000 mg
Other substances
1 mL is milk 1,030 mg, cooking oil 920 mg, ghee (melted) 910 mg, honey 1,420 mg. Lighter substances such as oil take up more volume for the same weight.
