ConverterkB to MB Converter
Convert smaller prefixed storage quantities into megabytes without hiding the base. Decimal mode divides kB by 1000; IEC Binary mode changes both labels and divides KiB by 1024.
Decimal SI is selected. Enter up to 120 significant digits using a decimal point or scientific notation with exponent magnitude no greater than 1000. Commas and negative quantities are rejected.
Choose The Prefix Family Before Dividing
Use Decimal SI when the source is labelled kB and MB: MB = kB / 1000. Use IEC Binary only when the intended units are KiB and MiB: MiB = KiB / 1024.
Upload Limits Need Their Own Convention
A service may publish a limit using decimal labels, binary units, or an implementation-specific rule. This converter changes units; it cannot determine whether a particular upload will be accepted.
Frequently Asked Questions
Yes in Decimal SI mode. In IEC Binary mode, 1024 KiB equals 1 MiB.
Binary powers use IEC labels such as KiB and MiB so a 1024-based result is not mislabeled as decimal kB or MB.
