1g is not the same as 1mL. This is because grams measure mass while milliliters measure volume. However, for water and other substances with a similar density, 1g of water approximately equals 1mL. For most other substances, their specific density determines the conversion. Always check the substance's density to convert between grams and milliliters accurately.

FAQs & Answers

  1. Why is 1 gram not always equal to 1 milliliter? Because grams measure mass and milliliters measure volume, their equivalence depends on the density of the substance. Only substances like water, with a density close to 1 g/mL, have near equal values.
  2. How do I convert grams to milliliters for different substances? To convert grams to milliliters, divide the mass (grams) by the density (grams per milliliter) of the substance.
  3. Does water have the same mass in grams as its volume in milliliters? Approximately yes. Since water has a density close to 1 g/mL, 1 gram of water is roughly equal to 1 milliliter.
