Bidirectional Conversion

This converter works both ways simultaneously:

Type in MB → GB updates automatically
Type in GB → MB updates automatically
No buttons to click - works as you type

Common Uses

File size calculations
Storage capacity planning
Data transfer estimations
Memory requirements

📏 How This Converter Works

This is a bidirectional converter that works in real-time using the binary system (base-2) where 1 GB = 1024 MB:

MB → GB: When you type in the MB field, the GB field automatically updates
GB → MB: When you type in the GB field, the MB field automatically updates
No swapping needed: Both conversions happen simultaneously
Real-time: Updates happen as you type, no button clicks required

// Bidirectional Conversion Logic (Binary):
GB = MB ÷ 1024
MB = GB × 1024

// Example 1: Type "2048" in MB
GB = 2048 ÷ 1024 = 2 GB

// Example 2: Type "2.5" in GB
MB = 2.5 × 1024 = 2560 MB
