File Size Converter
Convert between different file size units (KB, MB, GB, TB) with our easy-to-use calculator. This tool helps you understand and compare file sizes across different measurement units commonly used in computing and digital storage.
Common File Size References
- 1 KB: A simple text document
- 1 MB: A medium-quality photo
- 100 MB: A high-quality photo album
- 1 GB: About 250 MP3 songs
- 1 TB: About 250,000 photos or 250 movies
Conversion Result: 0.001 GB
Interpretation
1 MB is equal to 0.001 GB. This is a relatively small file size, suitable for documents and small images.
About File Size Measurement
File size refers to how much space a file occupies on a storage device. It's typically measured in bytes, with larger files using kilobytes (KB), megabytes (MB), gigabytes (GB), or terabytes (TB). Understanding file sizes helps with storage management, data transfer planning, and optimizing system performance.
File Size Measurement Units
Digital storage uses binary prefixes where each level is 1024 times the previous one:
- Kilobyte (KB): 1 KB = 1024 bytes
- Megabyte (MB): 1 MB = 1024 KB = 1,048,576 bytes
- Gigabyte (GB): 1 GB = 1024 MB = 1,073,741,824 bytes
- Terabyte (TB): 1 TB = 1024 GB = 1,099,511,627,776 bytes
Conversion Formula
The formulas to convert between these units are based on powers of 1024:
- From larger to smaller units: Multiply by 1024 for each step down
- From smaller to larger units: Divide by 1024 for each step up
For example: 1 GB = 1024 MB = 1024 × 1024 KB = 1024 × 1024 × 1024 bytes
Understanding File Sizes
Different types of files have typical size ranges:
Small Files (KB range)
Text documents, simple spreadsheets, and small images typically range from a few KB to a few hundred KB. These are ideal for email attachments and quick transfers.
Medium Files (MB range)
High-resolution images, MP3 songs, and short documents typically range from 1 MB to 50 MB. These are common for everyday computing tasks.
Large Files (GB range)
HD videos, software applications, and large databases typically range from 1 GB to tens of GB. These require significant storage space and bandwidth for transfer.
