**Langley (energy)**

**Langley (energy)**is the only unit in the category of

*Surface energy density*in our database. Langley (energy) has a dimension of MT

^{-2}where M is mass, and T is time. It can be converted to the corresponding standard SI unit J/m

^{2}by multiplying its value by a factor of 41850.

Note that the seven base dimensions are M (Mass), L (Length), T (Time), Q (Temperature), N (Aamount of Substance), I (Electric Current), and J (Luminous Intensity).
