Nanograms per Milliliter per Hour (ng/mL/hr)

Some medical tests report results in nanograms per milliliter per hour.

  • A nanogram is one-billionth of a gram. A gram is about 1/30 of an ounce.
  • A milliliter measures fluid volume equal to 1/1000 liter. A liter is a little bigger than a quart.
  • An hour is the time period that the amount of nanograms per milliliter is measured for.
