What these units are
Petabytes (PB). A petabyte here is 1,024 terabytes. It is used for data-centre and large-scale storage figures — a single rack of drives can hold several petabytes.
Megabytes (MB). A megabyte here is 1,024 kilobytes. It is used for photos, documents and short audio files; a photo from a phone camera is usually 2 to 5 megabytes.
Binary and decimal definitions diverge by about 2.4% at kilo and 7.4% at tera. This converter is binary throughout, so it will not match a manufacturer's decimal specification exactly.
Checking a petabytes to megabytes conversion
A data conversion looks like the metric chain but is not: this converter uses binary steps, so a kilobyte is 1,024 bytes and a megabyte is 1,024 kilobytes, which is what an operating system reports for a file.
The same names are also used in a decimal system of 1,000, and the gap compounds as the units grow. It is why a drive sold at a round decimal capacity shows less in a file manager, and why a bundle described in decimal gigabytes delivers fewer binary gigabytes than the number suggests.
Checking a data conversion means deciding which definition the number came from before doing the arithmetic. A figure of 500 GB is exact under one definition and about 465 GiB under the other, and no amount of rounding makes those the same quantity.
