Tread depth may be measured in 16ths of an inch, with 5/16 inches being a common depth for a new, all-season tire. Tires are generally unsuitable for snow and rain when their tread depth is less than 3/16 inch, due to the greater traction these conditions require. A deeper tread is needed in snow to maintain maneuverability and control.

Measurements needed to calculate RBC indices are the red blood cell count, hemoglobin, and hematocrit. The hematocrit is the percentage of blood by volume that is occupied by the red cells.The three main RBC indices are: 1  Mean corpuscular volume (MCV).2  The average size of the red blood cells expressed in femtoliters (fl). 3  MCV is calculated by dividing the hematocrit (as percent) by the RBC count in millions per microliter of blood, then multiplying by 10.easurements needed to calculate RBC indices are the red blood cell count, hemoglobin, and hematocrit.
