1 megabyte (MB) equals 1,048,576 bytes. Converting MB to bytes involves multiplying the number of megabytes by 1,048,576. For example, 1 MB equals 1,048,576 bytes.
Megabytes are units of digital storage, where 1 MB is equal to 1024 kilobytes, and each kilobyte is 1024 bytes. Therefore, to find the number of bytes in 1 MB, you multiply 1 by 1024, then again by 1024. This calculation gives 1,048,576 bytes, reflecting the binary system used in digital storage.
Conversion Result
1 MB converts to 1,048,576 bytes.

Conversion Formula
The formula to convert megabytes (MB) to bytes is: bytes = MB × 1024 × 1024. This works because in computing, 1 MB equals 1024 kilobytes (KB), and each KB equals 1024 bytes. Multiplying MB by 1024 twice converts to bytes. For example, 2 MB: 2 × 1024 × 1024 = 2,097,152 bytes.
Conversion Example
- Convert 3 MB to bytes:
- Multiply 3 by 1024 to get kilobytes: 3 × 1024 = 3072 KB.
- Then multiply 3072 by 1024 to get bytes: 3072 × 1024 = 3,145,728 bytes.
- Convert 0.5 MB:
- 0.5 × 1024 = 512 KB.
- 512 × 1024 = 524,288 bytes.
- Convert 10 MB:
- 10 × 1024 = 10,240 KB.
- 10,240 × 1024 = 10,485,760 bytes.

Conversion Definitions
mb
Megabyte (mb) is a unit of digital storage equal to 1,048,576 bytes in binary systems, used to measure file sizes, storage capacities, and data transfer amounts, especially in computer systems, where 1 MB equals 1024 kilobytes.
bytes
Bytes are the smallest addressable units of digital data storage, where 1 byte equals 8 bits; used to quantify data size, memory, and storage in computers, with larger amounts represented as kilobytes, megabytes, gigabytes, etc., based on powers of 1024.
Conversion FAQs
Why is 1 MB equal to 1,048,576 bytes instead of a million bytes?
This is because in digital storage, binary units are used where 1 MB equals 1024 kilobytes, and each kilobyte has 1024 bytes, leading to 1,048,576 bytes, not 1,000,000, which is decimal-based.
How does the conversion change if I use decimal units instead of binary?
Using decimal units, 1 MB would be considered 1,000,000 bytes, which is common in marketing storage devices, but in computing, binary units are standard, making 1 MB equal to 1,048,576 bytes.
Can I convert any fractional MB to bytes?
Yes, fractional MB can be converted by multiplying the decimal value by 1,048,576. For example, 0.75 MB equals 0.75 × 1,048,576 = 786,432 bytes.
Is there a quick way to estimate bytes from MB without calculator?
For rough estimates, multiply the MB value by about 1 million for decimal approximation or by 1,048,576 for binary conversions. For example, 2 MB is approximately 2 million bytes, but exact is 2,097,152 bytes.
