💾 How This Converter Works
This is a bidirectional converter for data storage units:
- Terabytes → Gigabytes: When you type in the TB field, the GB field automatically updates
- Gigabytes → Terabytes: When you type in the GB field, the TB field automatically updates
- No swapping needed: Both conversions happen simultaneously
- Real-time: Updates happen as you type, no button clicks required
// Bidirectional Conversion Logic:
gigabytes = terabytes × 1024
terabytes = gigabytes ÷ 1024
// Example 1: Type "2" in TB
gigabytes = 2 × 1024 = 2048 GB
// Example 2: Type "5120" in GB
terabytes = 5120 ÷ 1024 = 5 TB
gigabytes = terabytes × 1024
terabytes = gigabytes ÷ 1024
// Example 1: Type "2" in TB
gigabytes = 2 × 1024 = 2048 GB
// Example 2: Type "5120" in GB
terabytes = 5120 ÷ 1024 = 5 TB
