Data Storage Converter

How to Use the Data Storage Converter

The Data Storage Converter transforms digital file sizes and storage capacities between all standard units. Whether you are calculating how many photos fit on a memory card, comparing cloud storage plans, or understanding drive capacity differences, this tool makes digital storage math simple.

Supported Units

Convert between bits, bytes, kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB), and petabytes (PB). The converter supports both decimal (SI) and binary (IEC) interpretations of these units.

Decimal vs. Binary Units

Decimal (SI): 1 KB = 1,000 bytes, 1 MB = 1,000 KB, 1 GB = 1,000 MB. Used by storage manufacturers and for network speeds.

Binary (IEC): 1 KiB = 1,024 bytes, 1 MiB = 1,024 KiB, 1 GiB = 1,024 MiB. Used by operating systems and memory specifications.

This explains why a 1 TB drive shows about 931 GB in your operating system: 1,000,000,000,000 bytes / 1,073,741,824 = 931.32 GiB.

Common File Sizes

A text email: 10-50 KB. A high-resolution photo: 3-10 MB. A song (MP3): 3-5 MB. A movie (HD): 4-8 GB. A movie (4K): 20-100 GB. A full video game: 30-150 GB. These estimates help you judge how much storage you need.

Storage Planning

To estimate storage needs, multiply the average file size by the number of files. 1,000 photos at 5 MB each = 5 GB. 200 songs at 4 MB each = 800 MB. A 256 GB phone can hold approximately 50,000 photos, 60,000 songs, or 30 HD movies, though the operating system uses some space.

Frequently Asked Questions

Q: Why does my 1 TB drive show only 931 GB?

A: Drive manufacturers use decimal units (1 TB = 1,000,000,000,000 bytes), while operating systems use binary units (1 GiB = 1,073,741,824 bytes). Dividing the actual bytes by the binary GiB gives 931.32 GiB. No storage is missing; it is a labeling difference.

Q: What is the difference between Mbps and MBps?

A: Mbps (lowercase b) = megabits per second, used for internet speeds. MBps (uppercase B) = megabytes per second, used for file transfer speeds. Since 1 byte = 8 bits, divide Mbps by 8 to get MBps. A 100 Mbps connection downloads at about 12.5 MBps.

Q: How much cloud storage do I need?

A: For basic documents and emails, 15-50 GB is sufficient. For photo libraries, budget 1-2 GB per 200-400 photos. For video content, you may need 1-2 TB. Most users find 200 GB to 2 TB of cloud storage covers their needs. Assess your current data usage and add room for growth.
