Because a measure of mass is desired in the set of standard units.
The SI unit for mass is kilograms Grams or Millilters
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 In SI, density is measured in kilograms per cubic metre.
Density is measured in units of mass divided by units of volume. The SI unit is kilograms/meter3.
The best unit of mass to weigh a heavy suitcase would be kilograms (kg), as it is the standard unit of mass in the International System of Units (SI) and is commonly used for measuring luggage. Additionally, using kilograms allows for easy comparison to airline weight limits, which are typically specified in this unit. For smaller measurements, grams (g) could also be used, but kilograms are more practical for heavy items like suitcases.
