kilogram is the basic unit of mass in the international system of units.
what is the basic unit of mass in the international system of units?
kilogram
because mass and weight are separate quantities, they have different units of measure. in the international system of units (si), the kilogram is the basic unit of mass, and the newton is the basic unit of force. the non-si kilogram-force is also a unit of force typically used in the measure of weight. similarly, the avoirdupois pound, used in both the imperial system and u.s. customary units, is a unit of mass, and its related unit of force is the pound-force.

international system of electrical and magnetic units









































the international system of electrical and magnetic units is an obsolete system of units used for measuring electrical and magnetic quantities. it was proposed as a system of practical international units by unanimous recommendation at the international electrical congress (chicago, 1893), discussed at other congresses, and finally adopted at the international conference on electric units and standards in london in 1908. it was rendered obsolete by the inclusion of electromagnetic units in the international system of units (si) at the 9th general conference on weights and measures in 1948.
