list of units

[Chad Berkley]

Hi,

Below is a list of units that Tim and I came up with to add to EML.  I
also plan on adding everything at
http://physics.nist.gov/cuu/Units/units.html

The items with the * next to them are in the eml-unitDictionary.xml file
already. Please let me know ASAP if you have a favorite unit that is not
on the list.

---chris's suggestions---

Force:
 Dimensions: M L T^-2
    SI unit: newton (N)
 definition: the force that will impart 1 m s^-2 of acceleration
             to a mass of 1 kg

Pressure (Stress):
 Dimensions: M L^-1 T^-2
    SI unit: pascal (Pa)
 definition: the force per unit area (1 N m^-2)

Work (Energy, Heat, Torque):
 Dimensions: M L^2 T^-2
    SI unit: joule (J)
 definition: the energy required to accelerate a l kg object at one m
per
 second squared for the distance of one meter.

Power:
 Dimensions: M L^2 T^-3
    SI unit: watt (W)
 definition: the energy consumed over time (Joules per second)

Angle:
 Dimensions: dimensionless
    SI unit: radian (rad)
 definition: the angle that represents an arc length of one on a unit
circle (2  pi radians equals a circle)

We might want to also consider:

viscosity
specific energy
energy flux/productivity
metabolic rate
moment of inertia
