Mass mean diameter

  "id": "MLC-T-CHM-006983",
  "term": "Mass mean diameter",
  "field": "Chemistry",
  "definition": "A particle-size average defined through mass: the diameter of the sphere that would weigh the same as the average particle in a sample. Aerosol and powder size distributions are skewed, so this mean generally differs from the mass median diameter, which divides a sample into two halves of equal total mass.",
