+## Important Notes
+
+### Size Units: Decimal (SI) vs Binary (IEC)
+
+**This program uses decimal (SI) units for all size specifications**, matching the behavior of most system tools like `ls -lh`, `df -h`, and file managers:
+
+- **1 KB** = 1,000 bytes (not 1,024)
+- **1 MB** = 1,000,000 bytes (not 1,048,576)
+- **1 GB** = 1,000,000,000 bytes (not 1,073,741,824)
+- **1 TB** = 1,000,000,000,000 bytes (not 1,099,511,627,776)
+
+**Why decimal units?**
+- Consistency with system tools (`ls`, `df`, file managers)
+- Matches storage device marketing (a "1TB" USB drive has ~1,000,000,000,000 bytes)
+- Avoids confusion when comparing sizes across different tools
+- Industry standard for storage devices and file systems
+
+**Example:** When you request a 100GB pad, the program creates exactly 100,000,000,000 bytes, which will display as "100GB" in `ls -lh` and your file manager.
+
+**Note:** Some technical tools may use binary units (GiB, MiB) where 1 GiB = 1,024³ bytes. This program intentionally uses decimal units for user-friendliness and consistency with common tools.
