Digital Storage Converter
Digital Storage Converter tools make it simple to switch between different units of computer data — from bits to bytes, kilobytes to gigabytes, and beyond. Whether you’re checking file sizes, managing disk space, or studying computer science, understanding digital storage conversions is essential.
What Is a Digital Storage Converter?
A Digital Storage Converter helps you convert data storage units like bits (b), bytes (B), kilobytes (KB), megabytes (MB), and gigabytes (GB) accurately between binary (base 2) and decimal (base 10) formats.
Computers store information in binary code — sequences of 1s and 0s — while humans often measure storage using decimal prefixes (kilo, mega, giga). These two systems are similar but not identical, which often causes confusion.
Binary vs Decimal: The Two Systems of Data Measurement
1. Binary (Base 2) System
The binary system is based on powers of 2. Each new prefix represents 1024 (2¹⁰) times the previous one.
| Binary Unit | Symbol | Bytes |
|---|---|---|
| Byte | B | 1 |
| Kibibyte | KiB | 1,024 |
| Mebibyte | MiB | 1,048,576 |
| Gibibyte | GiB | 1,073,741,824 |
| Tebibyte | TiB | 1,099,511,627,776 |
Example:
1 GiB = 2³⁰ bytes = 1,073,741,824 bytes
2. Decimal (Base 10) System
The decimal system, used by most manufacturers, is based on powers of 10. Each prefix represents 1000 times the previous one.
| Decimal Unit | Symbol | Bytes |
|---|---|---|
| Byte | B | 1 |
| Kilobyte | KB | 1,000 |
| Megabyte | MB | 1,000,000 |
| Gigabyte | GB | 1,000,000,000 |
| Terabyte | TB | 1,000,000,000,000 |
Example:
1 GB = 10⁹ bytes = 1,000,000,000 bytes
Why Do Binary and Decimal Units Differ?
Although both systems use similar prefixes — kilo, mega, giga — they represent slightly different amounts. For example, 1 GiB (binary) is 1.074 GB (decimal). That’s why your “1 TB” hard drive might only show 931 GB of usable space in your computer.
Here’s the percent difference between binary and metric storage units:
| Binary Unit | Decimal Equivalent | Percent Difference |
|---|---|---|
| 1 KiB | 1.024 KB | 2.4% |
| 1 MiB | 1.049 MB | 4.9% |
| 1 GiB | 1.074 GB | 7.4% |
| 1 TiB | 1.100 TB | 10% |
How to Convert Digital Storage Units
Let’s walk through a simple example.
Example: Convert 5 GiB to Bytes
Formula:
5 GiB × 2³⁰ bytes per GiB = 5,368,709,120 bytes
To convert back:
5,368,709,120 bytes ÷ 2³⁰ = 5 GiB
This same principle works for any unit. To convert between gibibytes and tebibytes, multiply by 2³⁰ and divide by 2⁴⁰.
Formula:
1 GiB = 2⁻¹⁰ TiB = 1/1024 TiB.
If you’re not a fan of manual math, the Digital Storage Converter on CalculatorCave performs this instantly and accurately — no formulas needed.
Common Digital Storage Units Explained
Here’s a quick reference for the most common units you’ll encounter when using a Digital Storage Converter:
| Unit | Symbol | Base | Equivalent in Bytes |
|---|---|---|---|
| Bit | b | Binary | 1 bit |
| Byte | B | Binary | 8 bits |
| Kilobyte | KB | Decimal | 1,000 bytes |
| Kibibyte | KiB | Binary | 1,024 bytes |
| Megabyte | MB | Decimal | 1,000,000 bytes |
| Mebibyte | MiB | Binary | 1,048,576 bytes |
| Gigabyte | GB | Decimal | 1,000,000,000 bytes |
| Gibibyte | GiB | Binary | 1,073,741,824 bytes |
When you’re comparing file sizes — for example, when converting video or image data — understanding these units can help avoid confusion.
Understanding Bits vs Bytes
It’s easy to mix them up, but bits and bytes are not the same.
- 1 byte = 8 bits
- 1 bit = 1/8 byte
Bits (b) are used to measure data transfer speeds (like Mbps), while bytes (B) are used to measure data storage capacity (like MB or GB).
If you’re ever unsure, our conversion tools can help you find the right answer quickly.
When to Use a Digital Storage Converter
You’ll find a Digital Storage Converter useful in many scenarios:
- File Management: Checking how large files are across systems that use different unit standards.
- Hardware Comparison: Comparing disk space between binary and decimal formats.
- Network Calculations: Understanding data transfer metrics in bits vs bytes.
- Learning Purposes: Students studying computing or IT fundamentals.

Binary and Metric Prefixes in Detail
The International Electrotechnical Commission (IEC) standardized binary prefixes in 1998 to clear up confusion between binary and decimal units.
Binary prefixes (base 2):
kibi (Ki), mebi (Mi), gibi (Gi), tebi (Ti), pebi (Pi), exbi (Ei)
Each step increases by 2¹⁰ = 1024.
Decimal prefixes (base 10):
kilo (k), mega (M), giga (G), tera (T), peta (P), exa (E)
Each step increases by 10³ = 1000.
Tip: Always double-check whether your storage values are shown in binary (GiB) or decimal (GB) before conversion.
Real-World Example: Why Your 1TB Drive Shows 931GB
Manufacturers label storage in decimal units (1 TB = 1,000,000,000,000 bytes).
However, your computer calculates space in binary (1 TiB = 1,099,511,627,776 bytes).
So, when your operating system displays your 1 TB drive:
1,000,000,000,000 ÷ 1,099,511,627,776 = 0.91 TiB, or 931 GB.
That’s not lost data — just different measurement systems.
Quick Digital Storage Conversion Formulas
- Bits to Bytes: bits ÷ 8 = bytes
- Bytes to Bits: bytes × 8 = bits
- Kilobytes to Bytes: KB × 1000 = bytes
- Kibibytes to Bytes: KiB × 1024 = bytes
- Megabytes to Gigabytes: MB ÷ 1000 = GB
- Mebibytes to Gibibytes: MiB ÷ 1024 = GiB
These plain-text formulas work well for quick conversions without special symbols — perfect for SEO-friendly text and on-page snippets.
