Frequently Asked Questions
What is surface tension and why is it important?
Surface tension is the property of a liquid surface that allows it to resist external forces. It’s caused by cohesive forces between liquid molecules. Surface tension is crucial in numerous applications including microfluidics, coating processes, wetting phenomena, and bubble/droplet formation. It determines how liquids interact with surfaces and is fundamental in designing detergents, analyzing blood samples, and developing specialized coatings.
Why are dyne/cm and mN/m commonly used?
Dyne/cm is a CGS unit that has historically been used in scientific literature and remains common in chemistry and biology. The milliNewton/meter (mN/m) is an SI-derived unit that provides convenient numbers for typical liquids. Water at 20°C has a surface tension of approximately 72.8 mN/m or 72.8 dyne/cm, making these units practical for everyday laboratory measurements.
How do I convert between dyne/cm and N/m?
1 dyne/cm = 0.001 N/m. Our converter handles this automatically – 1 N/m = 1000 dyne/cm. The milliNewton/meter (mN/m) is numerically equivalent to dyne/cm: 1 mN/m = 1 dyne/cm.
What are typical surface tension values for common liquids?
Water at 20°C: ~72.8 mN/m (72.8 dyne/cm), Ethanol: ~22.1 mN/m, Mercury: ~485.5 mN/m, Olive oil: ~32 mN/m. Our converter helps translate these values to other units as needed for various applications. Surface tension generally decreases with temperature increases.
When would I use pound-force/foot units?
Pound-force/foot (lbf/ft) is sometimes used in US engineering standards, particularly in civil and mechanical engineering applications. It might be encountered in older technical literature or in specialized industries where imperial units are still preferred. 1 N/m = 0.0685218 lbf/ft, which our converter calculates automatically.
