Title: RE: Metric Steel Shapes
(for the S100x11 metric = an S4x7.7
millimeters which is approximately 4 inches.
>But how does
the 11 relate to 7.7 plf?
11 kilograms per meter is equivalent to 7.7 pounds per
foot. The metric series uses mass (not weight) per meter in the designator. In
the U.S. customary system gravity is applied (changing mass to weight) and the
length measurement changes as well to feet. The conversions for mass to
weight and meters to feet results in a divisor of 1.5 to get from metric to U.S.
