Byte to Megabyte Conversion Formulas
SI Standard (Decimal System)
Bytes to Megabytes Formula: MB = bytes ÷ 1,000,000 Megabytes to Bytes Formula: bytes = MB × 1,000,000
Examples:
- 5,000,000 bytes to megabytes: 5,000,000 ÷ 1,000,000 = 5 MB
- 3 megabytes to bytes: 3 × 1,000,000 = 3,000,000 bytes
IEC Standard (Binary System)
Bytes to Megabytes Formula: MB = bytes ÷ 1,048,576 Megabytes to Bytes Formula: bytes = MB × 1,048,576
Examples:
- 5,000,000 bytes to megabytes: 5,000,000 ÷ 1,048,576 = 4.77 MB
- 3 megabytes to bytes: 3 × 1,048,576 = 3,145,728 bytes

Frequently Asked Questions
How many bytes in a megabyte?
A megabyte contains 1,000,000 bytes using the SI (decimal) standard commonly used by storage manufacturers and web applications, or 1,048,576 bytes using the IEC (binary) standard traditionally used by operating systems and file systems.
How many bytes are in a megabyte?
There are 1,000,000 bytes in a megabyte according to the SI standard, or 1,048,576 bytes according to the IEC standard. The difference of 48,576 bytes (about 4.9%) becomes significant when working with large files or storage capacities.
How do you convert bytes to megabytes?
To convert bytes to megabytes, divide the byte value by 1,000,000 (SI standard) or 1,048,576 (IEC standard). Example: 5,000,000 bytes ÷ 1,000,000 = 5 MB (SI) or 5,000,000 bytes ÷ 1,048,576 = 4.77 MB (IEC).
How do you convert megabytes to bytes?
To convert megabytes to bytes, multiply the megabyte value by 1,000,000 (SI) or 1,048,576 (IEC). Example: 10 MB × 1,000,000 = 10,000,000 bytes (SI) or 10 MB × 1,048,576 = 10,485,760 bytes (IEC).
What does B to MB conversion mean?
B to MB conversion means converting from bytes (the smallest unit of digital storage) to megabytes (a unit representing millions of bytes). This conversion helps express large byte values in more manageable megabyte units for easier understanding and file management.
Why are there different standards for byte to megabyte conversion?
Different standards exist because computers use binary (base-2) arithmetic naturally, leading to 1 MB = 1,048,576 bytes, while humans prefer decimal (base-10) calculations, leading to 1 MB = 1,000,000 bytes. Storage manufacturers adopted decimal for marketing, while systems maintained binary for technical accuracy.
Which standard should I use for file size conversion?
Use SI standard (1,000,000 bytes = 1 MB) when working with storage devices, web applications, or marketing materials. Use IEC standard (1,048,576 bytes = 1 MB) when working with operating systems, file systems, or system-level programming that follows binary conventions.
