Gaussian units

Function to convert back and forth between SI and Gaussian units. The constants \(4 \pi \epsilon_0\) is equal to 1.

unitconvert.gaussian.factorGaussian(q)

Find the conversion factor that is used to convert the given quantity q to and from CGS Gaussian units and SI units

Args :

q (astropy quantity) : the quantity for which unit conversion must be done

Returns :

(dictionary) : the conversion factor in terms of \(4\pi\epsilon_0\)

Example :

>>> from unitconvert.gaussian import factorGaussian
>>> from astropy import units as u
>>> factorGaussian(1*u.A)
{'4 pi eps0' : 0.5 }

unitconvert.gaussian.fromGaussian(q, finalUnits)

Convert the given astropy quantity q in gaussian units to SI units

Args :

q (astropy quantity) : the quantity which needs to be converted

finalUnits (astropy quantity) : the base units to which quantity needs to be converted back.

Returns :

(astropy quantity) : the input quantity q in SI units

Example :

>>> from unitconvert.gaussian import fromGaussian
>>> from astropy import units as u
>>> fromGaussian(2.99792458e9 * u.Fr / u.s)
<Quantity 1. A>

unitconvert.gaussian.toGaussian(q)

Convert the given astropy quantity q in SI units to Gaussian units

Args :

q (astropy quantity) : the quantity which needs to be converted

Returns :

(astropy quantity) : the input quantity q in gaussian units

Example :

>>> from unitconvert.gaussian import toGaussian
>>> from astropy import units as u
>>> toGaussian(1*u.A)
<Quantity 2.99792458e+09 Fr / s>
