The units used for weight and mass are the same but there is a subtle difference in the meaning.
Take for instance an amount of substance that has a mass of 1kg. On earth it would weigh 1 kg. Taking the same object into space it would weigh nothing but would still have a mass of 1 kg. This is called inertial mass. Taking the object to the moon and it would still have a mass of 1 kg but would weigh about 1/6 of a kg. Weight is dependant on the gravitational field where the object is. This is a simplified explanation
The Atomic Mass is the mass (weight) of the element measured in atomic mass units (AMU)
weight
According to SI System of Units: Unit of Mass - Kilogram (Kg) Unit of Weight - Newton (N)
You use the formula weight = mass x gravity. In SI units, the gravity is 9.8 meters per second square, weight is in Newtons, mass is in kilograms.You use the formula weight = mass x gravity. In SI units, the gravity is 9.8 meters per second square, weight is in Newtons, mass is in kilograms.You use the formula weight = mass x gravity. In SI units, the gravity is 9.8 meters per second square, weight is in Newtons, mass is in kilograms.You use the formula weight = mass x gravity. In SI units, the gravity is 9.8 meters per second square, weight is in Newtons, mass is in kilograms.
Mass can be expressed in grams and other weight units.
The atomic mass of silver is approximately 107.87 atomic mass units.
The metric units used to measure the mass of your weight would be kilograms (kg) or grams (g).
Weight is typically measured in units such as pounds (lb) or kilograms (kg), whereas mass is measured in units such as grams (g) or kilograms (kg). Weight represents the force of gravity acting on an object, while mass is the amount of matter in an object.
Weight is mass x g, where g is the local gravitational field strength.
In the metric system (really called SI) weight is measured in units of newtons (lower case n to emphasize we are not talking about the scientist) and mass is in units of kilograms. W = mg (g =9.8) so weight in newtons equals mass in kilograms times 9.8.
Weight is measured in units called Newton, while mass is measured in units called grams and kilograms.
The SI unit of mass is grams. The pound is also a common unit of weight in America (on Earth, mass and weight are equivalent).
