How it works

Two steps, no account

1

Pick your units

SI force-per-length (N/m), CGS dyne/cm, or imperial force-per-length units.

2

Enter a value

The result updates instantly as you type, or as soon as you change either unit.

FAQ

Common questions

Is my data sent anywhere?
No. The conversion runs entirely in your browser — nothing is transmitted, logged, or stored.
What's a typical surface tension value?
Water at room temperature has a surface tension of about 72 mN/m (72 dyn/cm) — one of the highest among common liquids, which is why water beads up and small insects can walk on it.
