SI / Gaussian Formula Conversion Table - pgccphy.net

1 SI / Gaussian Formula Conversion Simpson, of Physical Sciences and EngineeringPrince George s Community CollegeJanuary 18, 2013 This Table may be used to convert any electromagnetic Formula between SI units and Gaussian units;simply make the substitutions indicated. To simplify the results, you may use"0 0D1= that in SI units there are two conventions for magnetic pole strength and dipole moment: one basedon theBfield (pole strength in A m), and one based on theHfield (pole strength in Wb). Both conventionsare given an example, given Coulomb s law in Gaussian units (FDq1q2=r2), we use the Table to create thecorresponding equation in SI "0/.q2=p4 "0/= "0/q1q2= / Gaussian Formula Conversion UnitsSI UnitsElectricfieldEp4 "0 EElectric potentialVp4 "0 VElectric displacementDp4 ="0 DElectric chargeqq=p4 "0 Electric charge density =p4 "0 Electric currentII=p4 "0 Electric current densityJJ=p4 "0 Electric polarizationPP=p4 "0 Electric dipole momentpp=p4 "0 Magnetic inductionBp4 = 0 BMagneticflux Bp4 = 0 BMagnetic vector potentialAp4 = 0 AMagnetic scalar potential' p4 0' Magnetic intensityHp4 0 HMagnetomotive forcemmfp4 0mmf1SI / Gaussian Formula Conversion UnitsSI UnitsMagnetic pole strength (B conv.)
