File Size Converter

Convert Byte, KB, MB, GB, TB file size units on a 1000 or 1024 basis.

Category: Converters

When to use?

Use it when an upload limit is "10MB" and you need the actual byte count, or to convert storage capacity to another unit. Also useful for comparing storage labeling (base 1000) vs. OS labeling (base 1024).

How to use

  • Enter the number.
  • Choose the base unit (Byte, KB, MB, GB, TB).
  • Choose base 1000 or base 1024.
  • See all units converted at once.

Input Explanation

Choose a number and unit to convert to all units from Byte to TB at once. Decimals are allowed.

Calculation Basis

Base 1000 (SI): 1KB = 1,000 Byte, 1MB = 1,000KB. Base 1024 (binary): 1KiB = 1,024 Byte, 1MiB = 1,024KiB. Storage makers use 1000; OSes mostly use 1024.

Usage Examples

  • Check upload limits - Convert a 10MB limit to Byte or KB.
  • Compare storage capacity - Quickly convert file sizes between GB and TB.
  • Convert data usage - Convert telecom data or download size to the unit you want.

Examples

  • 10MB (base 1000) = 10,000,000 Byte = 9.537 MiB (base 1024)
  • 1GB (base 1000) = 1,000,000,000 Byte ≈ 0.931 GiB (base 1024)

Cautions

  • Malformed input can cause parsing errors or broken output.
  • Confusing the 1000 and 1024 bases can cause misreadings.

Guides

File size unit conversion

1KB is 1,024B, 1MB is 1,024KB, 1GB is 1,024MB. Some makers (storage labeling) use 1,000 units, so actual capacity can look different from the OS display.

KiB/MiB difference

1KiB=1,024B (international) differs from 1KB=1,000B (SI). OS labeling differs, so check the unit first to avoid confusion.

FAQ

What is the difference between base 1000 and base 1024?

Storage labeling usually uses base 1000; OS file size calculations mostly use base 1024.

Can it convert up to TB?

Yes, it shows conversions from Byte to TB at once.

How do KB and KiB differ?

KB usually means 1000 bytes and KiB means 1024 bytes. This tool shows both.

Can I enter decimal sizes?

Yes, values with decimals like 1.5GB are converted.
