Binary Prefixes

Although these Binary prefixes were created for computing applications requiring multiples of 1024 (2¹⁰) they are not widely used. The original SI prefixes (based on multiples of 1000) are often misused and that can cause confusion. These prefixes are only used for binary scenarios (e.g. Computer Memory.)
