Newton/Metre

The newton per metre (N/m) is the SI unit of surface tension, measuring the force acting along the surface of a liquid per unit length. Water has a surface tension of approximately 0.0728 N/m at 20°C. Surface tension causes phenomena such as capillary action and the formation of soap bubbles. 


Millinewton/Metre

The millinewton per metre (mN/m) is the most commonly used unit of surface tension in practical measurements. One mN/m equals 10⁻³ N/m or 1 dyn/cm. Water's surface tension is about 72.8 mN/m at 20°C. Used in wettability studies and surfactant characterisation.
