The International System of Units (abbreviated SI from the French Le Système International d'Unités[1]) is the modern form of the metric system and is generally a system of units of measurement.
If the quantity changes during transport, the driver must show the change on the shipping document.
The quantity of dangerous goods in a means of containment may be described as “Residue — Last
