Kilogram per Metre (kg/m)

The kilogram per metre is the SI unit of linear density, the mass of a fibre, yarn, wire or cable per unit length. Textiles use the much smaller tex (10⁻⁶ kg/m).

Symbol: kg/m

Quantity: yarn count (linear density of yarns and fibres)

SI relation: kg/m is the coherent SI unit of yarn count.

Derivation: The coherent SI unit of linear density: mass in kilograms per metre of length.

Exact: yes, by definition

Typical uses

Ropes, cables and heavy tows
SI calculations of yarn and fibre properties
Converting between textile count systems
