⛽ How This Converter Works

This is a bidirectional converter that works in real-time:

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

// Bidirectional Conversion Logic:
MPG = KPL × 2.3521458
KPL = MPG ÷ 2.3521458

// Example 1: Type "15" in KPL
MPG = 15 × 2.352 = 35.28

// Example 2: Type "30" in MPG
KPL = 30 ÷ 2.352 = 12.76
