The correct abbreviation for kilogram is "kg". It is the standard international abbreviation for this unit of measurement. "Kgs" is not considered correct.
kg: This is the abbreviation for "kilogram," which is the base unit of mass in the metric system. It is used to describe a single unit of mass. For example, "5 kg" means 5 kilograms.
kgs: This is the plural form of the abbreviation "kg." While "kgs" is sometimes used colloquially, it's not the standard or widely accepted abbreviation for plural kilograms. The standard practice is to use "kg" for both singular and plural references. For example, "10 kg" is used whether you're talking about 10 kilograms or multiple units of 10 kilograms.
In summary, while "kg" is the correct and commonly used abbreviation for both singular and plural references to kilograms, "kgs" is not a standard abbreviation for the plural form.
