Newton per Meter (N/m)
The newton per meter (N/m) is the SI unit of surface tension — force per unit length at a fluid interface.
Newtons per meter quantify capillary action, bubble formation, and wetting behavior in coatings and microfluidics.

How to convert
Exact conversion factors in both directions, plus a worked example.
1 N/m = 1000 mN/m
1 mN/m = 0.001 N/m
To convert newton per meter to millinewton per meter, multiply by 1000.
To convert millinewton per meter to newton per meter, multiply by 0.001.
Example: convert 10 N/m to mN/m
10 × 1000 = 10000 mN/m
About these units
Short background on the units used in this conversion.
Millinewton per Meter (mN/m)
Millinewton per meter equals 0.001 N/m — a convenient SI subunit for moderate surface tensions.
Millinewtons per meter report interfacial tensions in tensiometry and polymer surface-energy studies.
Frequently asked questions
