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).
unit of work or energy in the International System of Units (SI); it is equal to the work done by a force of one newton acting through one metre. Named in honour of the English physicist James Prescott Joule, it equals 10 7 ergs, or approximately 0.7377 foot-pounds.
