Hi all,

Just to clarify, Einstein’s equation works for any coherent system. · In the case of SI, energy is in joules, mass in kilograms and speed of light in metres per second. · If you prefer the cgs system of units, then energy is in erg, mass in grams and speed of light in centimetres per second. · If you prefer the MTS system (used in France in industrial applications between the wars), then energy is measured in kilojoules, mass in tonnes and speed of light in metres per second. · If you prefer imperial of customary units, you will find that there is no coherent unit of energy.

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. 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. Einstein's famous equation, E = m x c^2 works only in metric: 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. Also, please use international date standard year-month-day , write date the way you write Numbers in Mathematics most signifikant -> least signifikant. do internet search on ISO date standard. The US passport does not use the twisted stupid date format with the day in the middle.

When I originally put up the site, about 15 years or so ago. I didn't have a smart phone then. Over the last few days I have been working on updates to the site. We need to let others know about the site and help eliminate the weights and measures KLUDGE and replace it with simple! ....Parker _______________________________________________ USMA mailing list USMA@lists.colostate.edu https://lists.colostate.edu/cgi-bin/mailman/listinfo/usma
