McKee Formula

The McKee formula estimates box compression strength or the maximum load a box can stand for a moment. If you enter ECT grade along with the caliper of the combined board and the length, width and depth of the box, the McKee formula calculates a theoretical compression value for your box. You can get ECT grades and calipers off the table in Box Performance under ECT.
