Frequently Asked Questions
How many Megabytes are in one Petabyte?
There are 1.07374e+9 MB in 1 PB. Digital storage uses binary (base-2) multiples: each step up is ×1024.
What is the difference between KB and Kb?
KB (kilobytes) measures storage capacity, while Kb (kilobits) measures data transfer rates. 1 byte = 8 bits, so 1 KB = 8 Kb. ISPs often advertise speeds in Mbps (megabits), while file sizes are in MB (megabytes).
Why is 1 KB = 1024 bytes instead of 1000?
Computers use binary (base-2), so storage naturally comes in powers of 2. 2^10 = 1024, which is close to 1000. The IEC introduced KiB/MiB/GiB for binary units, but KB/MB/GB with 1024 multipliers remains the industry standard in most operating systems.
