Units of Mass and Weight

👁️ 573

Mass and weight are associated standards in physics, however they may be no longer the same, and they are measured in distinctive units.


  • Mass is a measure of the quantity of rely in an object.
  • The SI (International System of Units) unit for mass is the kilogram (kg).
  • Other generally used units for mass encompass grams (g) and metric tons (tonnes). For example, 1 kilogram is identical to one thousand grams or 0.001 metric heaps.


  • Weight is the force exerted on an object due to gravity.
  • The SI unit for weight is the newton (N), that's derived from mass and the acceleration due to gravity. The method for weight is: Weight (N) = Mass (kg) × Acceleration because of gravity (m/s²).
  • On Earth, the usual acceleration due to gravity is about nine.81 m/s² (varies barely with area).
  • In a few contexts, the pound (lb) is also used as a unit of weight, specifically within the United States. However, the pound isn't always a unit in the SI machine, and it is able to purpose confusion because it's a unit of pressure (weight) rather than mass. In the imperial device, 1 pound of pressure is approximately identical to the burden of 0.4536 kilograms of mass.

mass is a degree of the amount of depend in an item and is usually measured in kilograms, grams, or metric heaps, even as weight is the pressure of gravity acting on an item's mass and is measured in newtons (SI) or kilos (imperial). The weight of an item can vary relying on the energy of the gravitational discipline, so an object could have the same mass no matter its area in the universe, however its weight might also trade.
