What unit is commonly used to measure RAM size?

The unit commonly used to measure RAM size is gigabytes (GB). Modern computer systems typically come with RAM capacities ranging from a few gigabytes to several tens of gigabytes. This range reflects the growing demands of applications and operating systems for memory space, especially in tasks involving multitasking, gaming, and resource-intensive applications.

While megabytes (MB) can measure RAM, they are more commonly associated with smaller memory sizes and have largely been phased out for current consumer-grade RAM specifications. Terabytes (TB) is a much larger unit typically used to describe storage capacities rather than RAM. Kilobytes (KB) represent an even smaller unit and are not practical for measuring RAM in contemporary computer systems. Therefore, gigabytes, being the standard unit for current RAM sizes, reflects the appropriate scale needed today.
