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 joule is the unit of energy in the International System of Units, also known as SI.It measures heat, electricity and mechanical work. It was named after English physicist James Prescott Joule.
