Because a measure of mass is desired in the set of standard units.
The SI unit for mass is kilograms Grams or Millilters
Kilograms are used as the standard unit of weight in most countries around the world, particularly those that have adopted the International System of Units (SI). This includes countries in Europe, Asia, Africa, and Australia, among others. The United States is one of the notable exceptions, where pounds are more commonly used. Overall, the metric system, including kilograms, is utilized by the majority of nations globally.
In the context of a system, "SI" stands for the International System of Units (Système international d'unités). It is the standard system of measurement used in science and engineering, providing a consistent framework for quantifying physical properties. The SI system includes base units such as meters for length, kilograms for mass, and seconds for time, among others.
Most of the world uses the SI system of measurements so weight is measured in grams, kilograms or tonnes. In the US the old ounces, pound and tons (Imoerial) system is used
Density is measured in units of mass divided by units of volume. The SI unit is kilograms/meter3.
The SI unit used to measure mass is kilograms. It is written as Kg.

The official SI unit for mass is the kilogram.
The ton (1000 kilograms), as well as the gram (1/1000 kilogram), the milligram (1/1000 gram) and the microgram (a millionth of a gram).
Both newtons and kilograms are SI units. Newtons (N) is the SI unit for weight or force. Kilograms (kg) is the SI unit for mass.
Grams and kilograms!
Kilograms
The unit is kilograms per cubic metre but kilograms per litre and grams per cubic centimetre are also used.
Mass is measured in kilograms (kg) in the SI system of measurement.
SI stands for Systems International. The unit for matter is kilograms. This unit can be used to describe the largest amount of matter to the smallest amount.
