MB or MiB? Convert storage without a hidden 4.86% gap
A clear method for choosing decimal and binary units before comparing file sizes.
Start with the unit, not the number
One megabyte (MB) is 1,000,000 bytes. One mebibyte (MiB) is 1,048,576 bytes. A value labeled only “megabytes” can therefore be ambiguous. Keep the original label when reporting a result; changing the label without converting the value changes its meaning. PixelDock lists decimal and binary units separately instead of treating them as aliases.
A worked example
Choose Digital storage, enter 10, select Megabyte (MB) and convert to Mebibyte (MiB). The unrounded result is about 9.5367431640625 MiB. The file has not become smaller; its byte count is still 10,000,000. Only the unit changed. For upload limits expressed as KB, verify whether the receiving service means decimal kilobytes or binary kibibytes.
Convert a batch without losing its order
Enter one numeric value per line in Batch values. Scientific notation such as 1e6 is accepted; commas used as thousands separators are rejected because they are ambiguous across locales. Choose the output precision, run the tool and download the CSV. Rows remain in input order. Empty or invalid lines produce an error rather than being silently omitted.
Round at the end
A displayed decimal result is rounded; it should not become the only source for a later high-precision calculation. Keep the original byte values for comparisons at an exact size boundary. A converted size says nothing about whether an image has the right dimensions or whether a platform accepts its content. Use the upload checker for those separate rules.
