Question 1

What is surface tension and how is it measured?

Accepted Answer

Surface tension is the force per unit length at a liquid surface, measured in N/m or dyne/cm. Water surface tension is about 72 mN/m at 20°C.

Question 2

How do I convert surface tension units?

Accepted Answer

Enter your value and the converter calculates equivalents. 1 N/m = 1000 mN/m = 1000 dyne/cm.

Question 3

What factors affect surface tension?

Accepted Answer

Temperature (higher = lower tension), surfactants, and liquid composition all affect surface tension. This converter handles unit conversion only.

Question 4

When are surface tension calculations important?

Accepted Answer

Surface tension is critical in coating processes, ink formulation, detergent design, printing, biomedical applications, and fluid dynamics.
