The most adequate unit is the metric tonne.
This unit is equal to 1 000 kg.
The weight of a bookcase is typically measured in units of mass, such as kilograms or pounds.
The metric unit most often used to describe weight is the Kilogram.
The unit of force in the SI (metric) system is the Newton. It's used to describe any force, no matter where the force came from. "Weight" is a good example of a gravitational force.
Kilogram.
You would use the metric unit "kilograms" to measure the weight of a bag of groceries.
The weight of a bookcase is typically measured in units of mass, such as kilograms or pounds.
The weights of most whales are measured in tons.
The metric unit most often used to describe weight is the Kilogram.
A scale
The unit of force in the SI (metric) system is the Newton. It's used to describe any force, no matter where the force came from. "Weight" is a good example of a gravitational force.
Weight actually refers to the force exerted by gravity. So weight would be a force measurement. Newton is a unit of force, as is Pound. But often the kilogram is used to also describe the weight of something, even though it is actually a mass unit.
Kilogram.
the Newton (N)
No metric unit will find the weight of the pumpkin for you. For that, you'll need some kind of a scale. However, once you've found the weight, you'll use a unit of force to describe it. The metric unit of force is the Newton. (NOT the kilogram.)
2.5
The SI unit would be Newtons or a capital N
