DM% = DW / WW *100

  • Where DM% is the dry matter percentage
  • WW is the total weight while wet
  • DW is the total weight while dry

Dry Matter Definition

Dry matter is a term typically used in the field of agriculture to describe the amount of feed that is dry weight, i.e. the percentage of weight of a feed that is actual food and not water.
