# [USMA 1341] Re: my metric

```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.

On your website, It is a good idea to explain that: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.

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.

Thank you to all who critiqued my web site:

and pointed out that it didn't look right on a smart phone.

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!
