Cells per square decimeter (dm\u00b2) is a useful unit of measure for understanding colony population dynamics and for developing management strategies, but, for practical field diagnostics it is easier to measure the width of a row of 10 cells measured side to side. A dm\u00b2 is an area 10 cm by 10 cm; cells on both sides of the comb area are counted. To convert cells per dm\u00b2 to cells per linear dm and then to mm per cell use equation 1:
\nEquation 1:<\/strong>
\ncells\/dm2 = 2.31 x N\u00b2 (where N is the number of cells per linear dm)
\nExample: 850 = 2.31 x (19.18)\u00b2
\nDivide 100 by cells per linear dm to obtain mm per cell
\nExample: 100 divided 19.2 = 5.2
\nTo convert cells per in\u00b2 to inches per cell:
\nEquation 2:<\/strong>
\ncells\/in\u00b2 = 2.31 x N\u00b2 (where N = number of cells per inch)
\nExample: 54.8 = 2.31 x (4.87)\u00b2
\nEquation 3:<\/strong>
\ncells\/dm\u00b2 = 15.5 x cells\/in\u00b2
\nExample: 850 = 15.5 x 54.8
\nThe values in this column represent the width of a single cell as measured between centers of opposing cell walls. The actual cell interior width is one cell wall thickness less than this value.<\/em>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
