Limitations

  • Gallons, quarts, pints and cups are US customary units. UK imperial units are about 20% larger and are not supported.
  • Converts volume to volume only. Converting to weight needs the density of the material.
  • Tablespoons, teaspoons and fluid ounces are not available.
  • Results show up to 6 decimal places. Values are not rounded during calculation, and a non-zero result that would display as 0 is shown in scientific notation.
