Surface Tension Converters
Convert surface tension units such as N/m, mN/m, and dyn/cm for wetting, capillarity, and lab reporting on one exact basis.
Scope & Verification
This hub groups related converter families so you can move from the category level to exact routes with one clear basis per page.
- Families are split so exact-factor, profile-based, density-based, and estimate-style pages do not collapse into one generic answer.
- Leaf pages keep calculator, common values, FAQ, and reverse routes aligned to the same assumption.
- Methodology and verification pages document how those assumptions are chosen and checked.
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.
How do I switch direction?
Open the reverse page for the opposite surface-tension route on the same N/m basis.
