The methods of standardization or calibration employed have much in common even in the cases that appear most diverse.
The joule (/ËdÊuËl/), symbol J, is a derived unit of energy in the International System of Units. It is equal to the energy transferred (or work done) to an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre (1 newton metre or NÂ·m).
The answer is: The change of 1 W ( watt ) unit of power measure equals = to 1.00 J/s ( joule per second ) as the equivalent measure for the same power type. Energy is expressed in Joules while power is expressed in Watts.
