Frequently Asked Questions
-
What does millinewnon per meter measure?
-
Millinewnon per meter quantifies the force per unit length at a liquid interface that resists surface deformation, representing surface tension.
-
Is 1 mN/m equal to 1 erg/cm²?
-
Yes, the conversion rate is 1 millinewnon per meter equals 1 erg per square centimeter.
-
Why convert between mN/m and erg/cm²?
-
Converting enables comparison and reporting of surface tension values in either SI or CGS unit systems, depending on scientific or industrial preferences.
Key Terminology
