Newton per meter quick reference
| Newton per meter | Pound-force per inch | Millinewton per meter | Dyne per centimeter |
|---|---|---|---|
| 1 N/m | ≈ 0.005710147155 lbf/in | = 1000 mN/m | = 1000 dyn/cm |
| 10 N/m | ≈ 0.05710147155 lbf/in | = 10000 mN/m | = 10000 dyn/cm |
| 100 N/m | ≈ 0.5710147155 lbf/in | = 100000 mN/m | = 100000 dyn/cm |
| 1000 N/m | ≈ 5.710147155 lbf/in | = 1000000 mN/m | = 1000000 dyn/cm |
Where the newton per meter fits
The next smaller surface tension unit is the gram-force per centimeter (gf/cm). 1 N/m ≈ 1.019716213 gf/cm, and 1 gf/cm = 0.980665 N/m.
The next larger surface tension unit is the pound-force per foot (lbf/ft). 1 N/m ≈ 0.06852176586 lbf/ft, and 1 lbf/ft ≈ 14.59390294 N/m.
