Understanding Data Size Units
Byte Units (Binary - Base 2)
Byte units use binary prefixes based on powers of 1024. This is the standard for computer storage because computers use binary addressing. 1 Kilobyte (KB) = 1,024 Bytes, 1 Megabyte (MB) = 1,024 KB, 1 Gigabyte (GB) = 1,024 MB, 1 Terabyte (TB) = 1,024 GB, 1 Petabyte (PB) = 1,024 TB.
Bit Units (Decimal - Base 10)
Bit units use decimal prefixes based on powers of 1000. This is the standard for network speeds and bandwidth measurements. 1 Kilobit (Kb) = 1,000 bits, 1 Megabit (Mb) = 1,000 Kb, 1 Gigabit (Gb) = 1,000 Mb, 1 Terabit (Tb) = 1,000 Gb. 8 bits = 1 byte.
Common Use Cases for Data Size Conversion
- Storage Planning - Calculate how many files fit on a storage device
- Bandwidth Monitoring - Convert between bits per second and bytes per second
- File Transfer Estimates - Calculate download/upload times
- Cloud Storage - Compare storage plans across providers
- Network Speed Testing - Convert Mbps to MB/s for real-world speeds
- Database Size Planning - Estimate database storage requirements

Data Size Reference Guide
Byte Units (Binary - Base 2)
1 KB = 1,024 Bytes
1 MB = 1,024 KB = 1,048,576 Bytes
1 GB = 1,024 MB = 1,073,741,824 Bytes
1 TB = 1,024 GB = 1,099,511,627,776 Bytes
1 PB = 1,024 TB = 1,125,899,906,842,624 Bytes
Bit Units (Decimal - Base 10)
1 Kb = 1,000 bits
1 Mb = 1,000 Kb = 1,000,000 bits
1 Gb = 1,000 Mb = 1,000,000,000 bits
1 Tb = 1,000 Gb = 1,000,000,000,000 bits
8 bits = 1 byte
Quick Reference
Bandwidth Conversion Guide
When dealing with internet speeds, it's important to understand the difference between bits and bytes:
Mbps to MB/s
Divide by 8 to convert Megabits per second to Megabytes per second.
100 Mbps ÷ 8 = 12.5 MB/sMB/s to Mbps
Multiply by 8 to convert Megabytes per second to Megabits per second.
10 MB/s × 8 = 80 MbpsFrequently Asked Questions
What's the difference between KB and KiB?
KB (kilobyte) traditionally means 1024 bytes, while KiB (kibibyte) explicitly means 1024 bytes. This converter uses KB, MB, GB as 1024-based (binary) units, which is the standard for storage.
Why are bit units different from byte units?
Bit units use decimal prefixes (1000) because network speeds are traditionally measured in decimal. Byte units use binary prefixes (1024) for storage because computers use binary addressing.
How do I convert MB/s to Mbps?
Multiply by 8. For example, 10 MB/s = 80 Mbps. This converter can help you with these conversions.
Is my data secure?
Absolutely! All conversions happen directly in your browser. Your data never leaves your device.
What's the largest unit supported?
Petabytes (PB) for storage and Terabits (Tb) for network speeds. These cover most practical use cases.
Can I use this tool offline?
Yes! Once the page loads, our Data Size Converter works completely offline. Perfect for when you don't have an internet connection.

Pro Tips for Data Size Conversion
- • Use byte units (KB, MB, GB) for storage calculations like hard drives and memory
- • Use bit units (Kb, Mb, Gb) for network speeds and bandwidth calculations
- • Remember 8 bits = 1 byte when converting between storage and network speeds
- • Copy any result and use it as input for multi-step conversions
- • Show all units to see bit conversions for network-related calculations
- • Use the example to see how 1 GB converts to all units
