Is 500mL Equal to Half a Kilogram? Understanding Density and Conversion

Discover the truth behind the conversion of 500mL to kilograms and how density impacts this measurement.

No, 500mL is not half a kilogram (kg). The conversion between milliliters (mL) and kilograms (kg) depends on the substance's density. For water, which has a density of 1 kg/L, 500mL (0.5 liters) equals 0.5kg. For other substances, you'll need their specific density to convert accurately. For example, oil, with a lower density, will weigh less than water for the same volume.

FAQs & Answers

  1. How is density calculated? Density is calculated by dividing mass by volume, often expressed as kilograms per liter (kg/L).
  2. What is the density of common liquids? The density varies; for example, water has a density of 1 kg/L, while oils typically have lower densities.
  3. Why do different liquids weigh differently? The weight of different liquids varies due to their unique densities, meaning the same volume can weigh differently.
  4. Can 500mL of any liquid weigh half a kilogram? Only if the liquid's density is 1 kg/L. Otherwise, you'll need to use the specific density for accurate weight.
