Byte Converter
Convert between digital storage units — B, KB, MB, GB, TB, PB, EB. Supports both 1000 and 1024 bases.
What is a byte converter?
A byte converter is a tool that converts between different digital storage units like bytes (B), kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB), petabytes (PB), and exabytes (EB). It helps you understand and compare data sizes across different measurement systems.
Why are there two conversion systems (base 1000 and 1024)?
Historically, computers used base 1024 (2^10) because it aligns with binary architecture. However, storage manufacturers use base 1000 for marketing purposes. This tool provides both systems so you can see the difference and choose the appropriate one for your needs.
Why does my hard drive show less capacity than advertised?
Hard drive manufacturers use decimal (base 1000) where 1 GB = 1,000,000,000 bytes, but operating systems like Windows use binary (base 1024) where 1 GiB = 1,073,741,824 bytes. This difference makes a 500 GB drive appear as approximately 465 GB in your system.
How accurate is the conversion?
All conversions are mathematically exact using full floating-point precision in your browser. Results are calculated instantly with maximum accuracy.
Is my data safe and private?
Absolutely. All conversions happen locally in your browser. No data is sent to any server. Your values never leave your device, ensuring 100% privacy.
Can I use this tool offline?
Yes. Once the page loads, all conversions work without an internet connection since everything runs in your browser.
What are the most common byte conversions?
The most common conversions are: KB to MB (for file sizes), MB to GB (for memory and storage), GB to TB (for large storage systems), and bytes to KB (for small files and data packets).
How do I convert file sizes for cloud storage?
Enter your file size in any unit (e.g., MB), and the converter instantly shows the equivalent in all other units. This helps you understand how much cloud storage you need and compare pricing plans.
What is the difference between KB and KiB?
KB (kilobyte) uses base 1000 where 1 KB = 1,000 bytes. KiB (kibibyte) uses base 1024 where 1 KiB = 1,024 bytes. KiB is the official IEC binary standard, but KB is more commonly used in everyday contexts.
How does this compare to spreadsheet formulas?
Unlike spreadsheet formulas that require manual calculation, this tool provides instant real-time conversion across all units simultaneously, with both base 1000 and base 1024 results displayed side by side for easy comparison.
What is the largest storage unit supported?
The largest unit supported is the exabyte (EB). 1 EB equals 1,000 petabytes or 1,000,000 terabytes in decimal, or 1,152,921,504,606,846,976 bytes in binary.
Why do I need a byte converter?
Byte converters are essential for understanding file sizes, comparing storage plans, calculating data transfer costs, estimating backup requirements, and communicating technical specifications across different measurement systems.
How to Use Byte Converter
Convert values between B, KB, MB, GB, TB, PB and EB, with a choice of decimal (1000) or binary (1024) base. Everything runs locally in your browser and no data is uploaded.
- Type the amount you want to convert into the input field, for example 500 or 2.5.
- Select the source unit from the dropdown: B, KB, MB, GB, TB, PB or EB.
- Read the equivalent values for all other units, from B up to EB, in the results.
- Switch between the 1000 base and the 1024 base to match how the value will be used.
- Copy any converted result straight from the list into your documents or configs.
Operating systems usually size memory with the 1024 base, while disk makers and network speeds use 1000 — choose the base that matches your comparison.
