Data Storage Converter - Byte, KB, MB, GB, TB
Convert digital data storage units between Byte, Kilobyte, Megabyte, Gigabyte, Terabyte, and Petabyte. Uses both binary (1024-based) and decimal (1000-based) standards. Essential for IT professionals, data scientists, and anyone working with file sizes and storage capacity.

Examples
MB to GB
Problem:
Convert 1500 MB to GB (decimal)
Solution:
- 1.1500 ÷ 1000 = 1.5
Result:1.5 GB
1500 MB equals 1.5 GB in decimal notation.
GiB to GB
Problem:
OS shows 256 GiB. How many GB decimal?
Solution:
- 1.256 × 1024 ÷ 1000 ≈ 262
Result:~262 GB
Binary vs decimal explains capacity differences.
Frequently Asked Questions
What is the difference between KB and KiB?
KB (kilobyte) = 1000 bytes (SI decimal). KiB (kibibyte) = 1024 bytes (IEC binary). Storage makers often use decimal; operating systems often use binary—causing apparent 'missing' capacity.
How many GB in 1 TB?
Decimal: 1 TB = 1000 GB. Binary: 1 TiB = 1024 GiB. RAM is usually binary; SSD/HDD labels are usually decimal.
Why is my HDD smaller than labeled?
Manufacturers use 1 GB = 10⁹ bytes; OS uses 1 GiB = 2³⁰ bytes. The gap is ~7% per GB and grows with capacity.
What comes after terabyte?
KB → MB → GB → TB → PB (petabyte) → EB → ZB → YB. Each step ×1000 (decimal) or ×1024 (binary).
