About Disk Space Units
This calculator supports both binary (base-2) and decimal (base-10) units:
- Binary (Base-2): 1 KB = 1,024 Bytes, 1 MB = 1,024 KB, etc.
- Decimal (Base-10): 1 KB = 1,000 Bytes, 1 MB = 1,000 KB, etc.
About Disk space calculator Tool
In today’s digital world, managing storage space efficiently is crucial—whether you’re a tech enthusiast, IT professional, or just someone trying to organize their files. Disk Space Calculator is a powerful web-based tool designed to simplify storage calculations, conversions, and more.
Storage units can be confusing, especially when dealing with binary (base-2) and decimal (base-10) measurements. Misunderstanding these differences can lead to incorrect storage estimations, wasted space, or even data loss.
Our Disk Space Calculator eliminates the guesswork by providing:
✅ Accurate unit conversions (Bytes, KB, MB, GB, TB)
✅ Comparison between different storage units
✅ Mathematical operations (multiplication, division, percentages)
✅ File storage estimation
✅ RAID storage calculations (RAID 0, 1, 5, 6, 10)
1. Unit Converter
Easily switch between binary (1 KB = 1024 B) and decimal (1 KB = 1000 B) units. Convert between:
Bytes (B)
Kilobytes (KB)
Megabytes (MB)
Gigabytes (GB)
Terabytes (TB)
2. Unit Comparison
Need to know how many MB are in 5 GB? Or how many KB make up 1 TB? The comparison tool instantly shows the relationship between different storage units.
3. Advanced Calculations
Multiplication & Division – Calculate total storage when scaling up or splitting data.
Percentage Calculation – Determine how much space a certain percentage of storage occupies.
Free Space Calculation – Track how much storage is left after usage.
4. File Storage Estimation
Planning to store thousands of files? Enter the average file size and number of files, and the calculator will estimate the total storage required.
5. RAID Storage Calculator
Setting up a RAID array? This tool helps you understand:
Usable storage based on RAID level (0, 1, 5, 6, 10)
Efficiency & redundancy trade-offs
Minimum drive requirements for each RAID type
✔ IT Professionals & SysAdmins : Plan server storage and RAID setups accurately.
✔ Developers : Estimate app storage requirements.
✔ Photographers & Videographers : Calculate storage needs for large media files.
✔ General Users : Understand disk space before buying a new hard drive or cloud storage.
