Surface tension converter
The skin on a liquid surface. 5 units, converted from one table of exact factors.
—
1 newton/meter in every other surface tension unit
Computed by the same engine that runs the converter above, so these can never drift apart from it.
| From | Equals | Unit |
|---|---|---|
| 1 newton/meter | 1,000 | millinewton/meter (mN/m) |
| 1 newton/meter | 1,000 | dyne/centimeter (dyn/cm) |
| 1 newton/meter | 1,000 | erg/square centimeter (erg/cm²) |
| 1 newton/meter | 0.06852176586 | pound-force/foot (lbf/ft) |
What each unit actually is
Most converters give you a number and stop. Where a figure is exact by definition we say so, and where it is an average or shifts with conditions we say that too — that is usually the thing you needed to know.
| Unit | Symbol | What it actually is |
|---|---|---|
| newton/meter | N/m | SI. |
| millinewton/meter | mN/m | Water is about 72 of these. |
| dyne/centimeter | dyn/cm | Identical to mN/m. The usual lab unit. |
| erg/square centimeter | erg/cm² | Also identical — energy per area is the same quantity. |
| pound-force/foot | lbf/ft |
