MN/m

meganewton per meter

Spring constantexact by definition

The meganewton per metre is 10⁶ N/m, exact by prefix. It is the stiffness scale of structural elements rather than springs: bridge bearings, machine foundations, pile head stiffness and the axial stiffness of a steel column all land here.
