Millinewton per meter quick reference
| Millinewton per meter | Dyne per centimeter | Newton per meter | Gram-force per centimeter |
|---|---|---|---|
| 1 mN/m | = 1 dyn/cm | = 0.001 N/m | ≈ 0.001019716213 gf/cm |
| 10 mN/m | = 10 dyn/cm | = 0.01 N/m | ≈ 0.01019716213 gf/cm |
| 100 mN/m | = 100 dyn/cm | = 0.1 N/m | ≈ 0.1019716213 gf/cm |
| 1000 mN/m | = 1000 dyn/cm | = 1 N/m | ≈ 1.019716213 gf/cm |
Where the millinewton per meter fits
The next larger surface tension unit is the gram-force per centimeter (gf/cm). 1 mN/m ≈ 0.001019716213 gf/cm, and 1 gf/cm = 980.665 mN/m.
