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. customary units.
