A Helen is a unit of measurement based on Helen of Troy. She was known as "the face that launched a thousand ships", therefore 1 milliHelen is the amount of beauty needed to launch a single ship. A negative quantity of Helen is the power to beach ships.
Derivation
Using SI units, for the average sailboat with a mass of 4012.0 kg [1], and launching it to a speed of 1 m/s. If a fleet has one thousand of these average sailboats, that is a total mass of 4.012*10^6 kg. If the fleet accelerates to a sailing speed of 6 knots [2] over the course of 1 hour, which is an acceleration of 8.57*10^-4 meters per second per second to reach a top speed of 3.08 m/s, that is a force of 3.44 kilo-newtons.
