erg/sec
A form of the metric unit for power. It is equal to 10-10 kilowatts (see scientific notation).

erg
(a) The cgs unit of energy; the work done by a force of 1 dyne acting over a distance of 1 cm. 1 erg = 10-7joules = 1 g cm2 s-2. (sometimes called dyne cm) [H76] ...

erg - (n.)
A unit of energy in the metric system, corresponding to the work done by a force of one dyne (the force that is required to accelerate one gram by one cm/sec2) producing a displacement of one centimeter.

1 Jy = 10-23 erg s-1 cm-2 Hz-1 (cgs)
The flux density in Jy can be converted to a Magnitude basis, for suitable assumptions about the spectrum. For instance, converting an AB magnitude to a flux-density in microjansky is straightforward: ...

with cgs units [erg cm-3 s-1] and where 'ff' stands for free-free, 1.4x10-27 is the condensed form of the physical constants and geometrical constants associated with integrating over the power per unit area per unit frequency, ...

27372 x 10-21 erg/gauss. See physical constants, tables. Bohr magneton is sometimes used as a synonym for nuclear magneton. Bohr radius (symbol a0) The smallest possible radius of an electron orbit in the Bohr model of the atom, 5.

The average luminosity of the Sun is about 4x1033 erg/sec. Astronomers often express units for other objects in terms of solar units--it makes the resulting numbers smaller and easier to deal with.

-Hydrogen fusion produces 8Ã-1018 erg/g while helium fusion produces 8Ã-1017 erg/g.
^ For a detailed historical reconstruction of the theoretical derivation of this relationship by Eddington in 1924, see: Lecchini, Stefano (2007).

4 x 10-37 L(Hb) erg/sec. Ha is about 2.9 times as strong as Hb under low-density conditions.

Where, T is the temperature (K), λ = wavelength (cm), c = speed of light, k = Boltzmann's constant (1.37 x 10-18 erg/K), and h = Planck's constant (6.626 x 10-27 erg sec).

The quantity h (Planck's constant) divided by 2: = 1.054 x 10-27 erg seconds. [H76]
