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 unit of energy in the SI system of units is the Joule. One Joule of energy is equal to the work done by a force of 1 Newton acting over a distance of 1 meter.
