Surface Tension Converter
Convert surface tension among N/m, dyn/cm, and mN/m using N/m as the reference.
How to use
- Enter surface tension and choose the experimental and target notation among N/m, dyn/cm, and mN/m.
Capabilities and scope
Compare force per unit length at a liquid interface across SI and CGS-style notation.
How it works
N/m is the reference; both 1 dyn/cm and 1 mN/m equal 0.001 N/m.
Example
72 mN/m is 0.072 N/m and 72 dyn/cm.
Useful for
- Convert liquid surface tension from mN/m to N/m
- Compare dyn/cm literature with SI
- Normalize experimental units
Before you use it
- Real surface tension depends on temperature, composition, and interface conditions; the converter does not correct those conditions.

Frequently asked questions
Why are mN/m and dyn/cm numerically equal?
Both equal 0.001 N/m, so their numeric values match.
