Well said, one minor correction " If you use the volt as a unit of electrical voltage" should have read "If you use the volt as a unit of electrical potential difference".

I don't have children, i have met people who went thru US school system and don't know what is a km. we need a law that explicitly requires teaching the following before obscurantist foot/pound US congress passed pl 39-183, the metric act of 1866, which went into effect in 1866 and prohibits refusing to trade in metric and prohibits refusing to accept a court document because it is in metric. US congress passed the fair labeling act of 1994, which was signed by president Clinton, requires metric units on all labels. US is member of la convention du metre. From a scientific viewpoint All the units of electricity and magnetism are derived from the meter, kilogram, Coulomb and second. Till exempel, the volt is defined, such as if an electric charge of 1 Coulomb changes electric potential by 1 volt, there is energy exchange of 1 joule. As a consequence, an electrical current of 1 amp thru 1 volt for 1 sec delivers energy of 1 joule, which is the kinetic energy of 2 kg moving at 1 m/s. ON THE OTHER HAND, THERE IS NO RELATION BETWEEN AMPERE, VOLT, JOULE AND THE STUPID OBSCURANTIST FOOT/POUND. If you use the volt as a unit of electrical voltage, you are using the metric system, 1 volt = 1 Joule/Coulomb and the joule is derived from meter, kilogram and second, THERE IS NO RELATION BETWEEN AMPERE, VOLT, JOULE AND THE STUPID OBSCURANTIST FOOT/POUND. Similarily, the unit of magnetic field, 1 Tesla is defined as if an electric charge of 1 Coulomb is moving at a velocity of 1 m/s perpendicular to a magnetic field of 1 Tesla, it experiences a force of 1 Newton perpendicular to both the magnetic field and velocity vectors. 1 Newton is the force that accelerates 1 kilogram by 1 m/(s^2). THERE IS NO RELATION BETWEEN Tesla, Newton AND THE STUPID OBSCURANTIST FOOT/POUND. Einstein's famous equation, E = m x c^2 works only in metric and other coherent systems: m is in Kg, c = 3 x 10^8 m/s , E = energy in joules, 1 wh = 3600 (watt-sec or joules). 1 more reason to dump the stupid moronic idiotic foot/pound system and switch to metric. Thus in the metric system, 1 Kg of matter that gets completely converted into energy, would generate 9 x 10^16 Joules or (9 x 10^16/3600000) = 2.5 x 10^10 KWH To apply Einstein's famous equation in non-metric units, the unit of energy would be defined as the kinetic energy of 2 units of mass moving at a speed of 1 unit of length/sec and the speed of light in vacuum expressed in units of length/sec. Since we already have 1 Volt x 1 Amp x 1 sec = 1 Joule of electrical energy, for non-metric units, you would have to define another obscure unit of energy. As a direct consequence of Maxwell's equations, the electric and magnetic fields of an electromagnetic wave traveling in vacuum, which are 3 dimensional vectors, are perpendicular to each other and the ratio of their magnitude E/B = c , the speed of light in vacuum 299792458 m/s so if the magnetic field B=1 tesla,the electric field E=299792458 newton/coulomb. it is important to shove facts of science in the face of obscurantist ignorants. i am thinking about putting a petition on change.org .
