Formula Used
Decimal method: Bytes = GB × 1,000,000,000
Binary method: Bytes = GB × 1,073,741,824
Bits conversion: Bits = Bytes × 8
Equivalent units: Unit value = Bytes ÷ selected unit multiplier
Use the decimal method for vendor storage labels and the binary method for operating system style calculations or memory-oriented comparisons.

FAQs
1. What is the difference between decimal and binary conversion?
Decimal uses 1 GB = 1,000,000,000 bytes. Binary uses 1 GB = 1,073,741,824 bytes. The binary result is larger because it follows powers of 1024 instead of 1000.
2. Why do storage devices and operating systems show different sizes?
Manufacturers often label capacity with decimal units, while operating systems may interpret values with binary multipliers. That difference creates smaller displayed free space than the box label suggests.
3. Can I convert fractional GB values?
Yes. The calculator accepts decimal inputs such as 0.25, 2.75, or 4.7 GB. This is useful for estimating file sizes, download limits, and partial storage allocations.
4. Should I use decimal mode for SSD and HDD capacities?
Usually yes. Drive vendors commonly market capacity with decimal units. Decimal mode gives a closer match to published storage specifications on retail packaging and product pages.
5. When is binary mode more useful?
Binary mode helps when comparing system-reported capacities, memory calculations, virtualization limits, and technical environments where 1024-based scaling is expected.
6. Why does the calculator also show bits?
Bits are useful for networking, bandwidth, and transfer rate discussions. Since one byte equals eight bits, showing both values helps compare storage and communication measurements.
7. What does the graph represent?
The graph shows how your converted value scales across related units. It helps you quickly compare the same quantity in bytes, smaller units, and larger units without manual calculations.
8. What is included in the CSV and PDF downloads?
Both exports include the current conversion table generated from your latest input. That makes it easy to save results for reports, documentation, audits, or client communication.
