Yes, 1 ml of water at room temperature is approximately equal to 1g. This relationship is due to the density of water, which is roughly 1 gram per milliliter (g/ml). This convenient ratio makes it easy to convert between milliliters (volume) and grams (weight) for water, simplifying cooking measurements, scientific experiments, and more. However, this equivalence does not hold true for all substances due to variations in density.

FAQs & Answers

  1. Why is 1 ml of water equal to 1 gram? 1 ml of water equals approximately 1 gram because water has a density of about 1 gram per milliliter at room temperature, making volume and weight measurements directly comparable.
  2. Does 1 ml of all liquids equal 1 gram? No, 1 ml equals 1 gram only for water due to its density. Other liquids have different densities, so their weight for the same volume varies.
  3. How does temperature affect water’s density? Water’s density slightly changes with temperature; at room temperature, it's about 1 g/ml, but it can be less or more at higher or lower temperatures.
