Byte Converter

What is Byte Converter?

Byte Converter transforms values between digital storage units from bytes through kilobytes, megabytes, gigabytes, terabytes, and petabytes. It supports both binary (1024-based, IEC standard: KiB, MiB, GiB) and decimal (1000-based, SI standard: KB, MB, GB) calculation modes. The tool displays all unit conversions simultaneously and clarifies the difference between binary and decimal measurements.

Cloud architects estimating storage costs, network engineers calculating bandwidth requirements, and system administrators planning capacity. The tool runs entirely in your browser — your data never leaves your device.

How to Use Byte Converter

1. Enter a numeric value and select its current unit from the dropdown
2. View instant conversions to all other units displayed in a comparison table
3. Toggle between binary (1024-based) and decimal (1000-based) calculation modes
4. Reference the conversion factor table to understand the multiplier between each unit pair
5. Copy any converted value for use in documentation or calculations

Common Use Cases

• Understanding why a 1 TB hard drive shows as 931 GB in the operating system (decimal vs binary)
• Calculating bandwidth requirements by converting between megabits per second and megabytes per second
• Estimating cloud storage costs by converting file sizes between units for pricing calculations
• Converting RAM specifications between GiB (what the OS reports) and GB (what manufacturers advertise)
• Calculating API payload sizes and comparing against provider limits specified in different units

Pro Tips

• Hard drive manufacturers use decimal (1 TB = 1,000,000,000,000 bytes) while operating systems use binary (1 TiB = 1,099,511,627,776 bytes) — this is why your new drive appears smaller than advertised
• Network bandwidth is measured in bits (Mbps) while file sizes are in bytes — divide your internet speed by 8 to get the theoretical maximum download speed in megabytes per second
• AWS S3 and most cloud providers charge per GB (decimal) for storage but per GiB (binary) for data transfer — always check which standard a provider uses before calculating costs
