Common surface tension conversions

Newtons per meter to millinewtons per meter:
1 N/m = 1,000 mN/m

Millinewtons per meter to newtons per meter:
1 mN/m = 0.001 N/m

Dynes per centimeter to newtons per meter:
1 dyn/cm = 0.001 N/m

Newtons per meter to dynes per centimeter:
1 N/m = 1,000 dyn/cm

Where surface tension conversions are used

Surface tension conversions are useful for fluids, coatings, inks, paints, detergents, droplets, capillary action, lab testing, material science, chemistry, and fluid mechanics.

Use this converter when comparing SI, CGS, and U.S. customary surface tension units.

What your surface tension result means

Your result shows the entered surface tension converted from the starting unit into the selected ending unit. The calculator also shows the conversion rate used so you can verify the calculation.

For engineering, lab, and fluid calculations, make sure the surface tension unit matches your test method, material data sheet, fluid chart, or formula.

Surface tension converter tips

Frequently asked questions

What is surface tension?

Surface tension is the force per unit length acting along the surface of a liquid.

What is the SI unit of surface tension?

The SI unit of surface tension is newtons per meter, abbreviated as N/m.

Is mN/m the same as dyn/cm?

Yes. 1 millinewton per meter equals 1 dyne per centimeter.

How many dynes per centimeter are in one newton per meter?

One newton per meter equals 1,000 dynes per centimeter.

Can I convert negative surface tension values?

This converter is designed for surface tension magnitude conversions, so it uses non-negative values.
