Surface Tension Converters
Convert surface tension units used in wetting, capillarity, detergents, and materials science references.
Explanation
Surface tension is force per unit length at a liquid interface. This hub anchors factors to N/m so SI and CGS relationships stay consistent and reversible. Typical uses include wetting behavior, capillary effects, detergents, and materials science measurements. dyn/cm from CGS and mN/m from SI lab practice are cleanly related through fixed multiplicative factors.
Surface Tension pages are organized by conversion direction so mirror leaves remain aligned and comparable.

Frequently Asked Questions
What is surface tension?
Surface tension is force per unit length acting along a liquid interface.
What is the SI unit of surface tension?
The SI unit is newton per meter (N/m), often shown in labs as mN/m.
Why does dyn/cm appear in older literature?
dyn/cm comes from the CGS system and is still common in older publications and some lab references.
Why is mN/m common in labs?
Typical liquid values are often in tens of millinewtons per meter, so mN/m is convenient.
Are these conversions purely multiplicative?
Yes. Surface tension unit conversions here use fixed multiplicative factors with no offsets.
