# What is the SI unit for weight?

**force**, which in the International System of Units (SI) is

**the newton**. For example, an object with a mass of one kilogram has a weight of about 9.8

**newtons**on the surface of the Earth, and about one-sixth as much on the Moon.

Then, what is the SI unit of mass and weight?

The kilogram is the **SI unit of mass** and it is the almost universally used standard **mass unit**. The associated **SI unit** of force and **weight** is the Newton, with 1 kilogram weighing 9.8 Newtons under standard conditions on the Earth's surface.

Also, what is the unit of weight and why? The SI **unit of weight** is the newton (which is a **unit** of force). This is because “**weight**” is the a measure of the force on a body by gravity. The kilogram is the SI **unit** of mass which is a measure of the amount of matter that a body contains.

kilogram

What is standard unit weight?

**Standard unit** of Mass or **Weight**: The **standard unit** of mass is kilogram and in short it is written as kg. It is used to measure the mass of heavy objects such as bags of grain, stones, etc. The smaller **unit** of mass is gram and in short it is written as g.
