1. What is GB to MB Conversion?

The GB to MB conversion calculates how many megabytes are in a given number of gigabytes. On Windows 10 and most computer systems, 1 gigabyte equals 1000 megabytes in decimal (base 10) notation.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( MB \) — Megabytes
• \( GB \) — Gigabytes

Explanation: This is the standard decimal conversion used by Windows 10 for storage measurements.

3. Windows 10 Storage Units

Details: Windows 10 uses decimal (base 10) units for storage capacity:

• 1 kilobyte (KB) = 1000 bytes
• 1 megabyte (MB) = 1000 KB = 1,000,000 bytes
• 1 gigabyte (GB) = 1000 MB = 1,000,000,000 bytes

4. Using the Calculator

Tips: Enter the number of gigabytes (GB) you want to convert. The calculator will automatically compute the equivalent megabytes (MB).

5. Frequently Asked Questions (FAQ)

Q1: Why does Windows use 1000 instead of 1024?
A: Windows 10 follows the International System of Units (SI) standard which uses decimal (base 10) prefixes for storage measurements.

Q2: What's the difference between decimal and binary MB/GB?
A: In binary (base 2), 1 GB = 1024 MB. Some systems use binary units, but Windows 10 uses decimal.

Q3: Does this conversion apply to RAM?
A: No, RAM capacity is typically measured in binary units where 1 GB = 1024 MB.

Q4: How accurate is this conversion?
A: The conversion is mathematically precise for decimal storage measurements.

Q5: Why does my drive show less space than advertised?
A: This is due to the difference between decimal (advertised) and binary (actual) measurements, plus some space is used by the file system.
