Common conversions
Useful surface tension conversion factors
| Conversion | Factor | Typical use |
|---|---|---|
| mN/m to N/m | N/m = mN/m / 1000 | Fluid property data |
| dyn/cm to N/m | N/m = dyn/cm x 0.001 | CGS surface tension data |
| N/m to dyn/cm | dyn/cm = N/m x 1000 | Lab reports and references |
| lbf/ft to N/m | N/m = lbf/ft x 14.59390294 | Imperial engineering data |
| gf/cm to N/m | N/m = gf/cm x 0.980665 | Legacy fluid data |
| kgf/m to N/m | N/m = kgf/m x 9.80665 | Gravity-based units |
How it works
Surface tension conversion method
2. Convert to target units
target value = base value / target unit factor
The selected result and table values are calculated from the same base value.
3. Check precision
rounding depends on scale
Very small and very large values use compact scientific notation to stay readable.
FAQ
Surface tension converter questions
How do you convert mN/m to N/m?
Divide mN/m by 1000 to convert millinewtons per meter to newtons per meter.
Is dyn/cm equal to mN/m?
Yes. One dyn/cm is equal to one mN/m, and both equal 0.001 N/m.
What is surface tension?
Surface tension is force per unit length at a fluid interface, commonly used for capillarity, wetting, and droplet behavior.
