250ml and 250g are not necessarily the same. The equivalence depends on the substance's density. For water, they are similar, as 1 ml of water equals 1 gram. However, for substances with different densities, 250ml will not equal 250g. For example, 250ml of oil weighs less than 250g due to oil's lower density. To convert between them accurately, knowledge of the substance's density is necessary. Use weight and volume conversion formulas when exact measurements are important.

FAQs & Answers

  1. What is the difference between milliliters and grams? Milliliters (ml) measure volume, while grams (g) measure weight. The two can be equivalent for substances with a density of 1, like water, but vary for others.
  2. How do you convert milliliters to grams? To convert milliliters to grams, multiply the volume in milliliters by the substance's density (in g/ml). For example, 250ml of water equals 250g, but 250ml of oil weighs less due to a lower density.
  3. Do all liquids have the same density? No, different liquids have different densities. This affects weight measurements; for example, oil is less dense than water, so the same volume of oil weighs less than that of water.
  4. Why is it important to know a substance's density? Knowing a substance's density is crucial for accurate conversions between volume and weight, which is important in cooking, science, and other applications where precision is key.
